value analysis and value engineering
TRANSCRIPT
ORIGIN
Value Engineering began at General Electric Co during World War II Because of the
war there were shortages of skilled labor raw materials and component parts Lawrence
Miles and Harry Erlicher at GE looked for acceptable substitutes They noticed that
these substitutions often reduced costs improved the product or both What started out as
an accident of necessity was turned into a systematic process They called their technique
as ldquoValue Analysisrdquo
In the year 1954 US Navy Bureau of ships adopted same technique in their effort at
lsquocost avoidancersquo during the design stage and saved millions of dollars They named it as
ldquoValue Engineeringrdquo VE follows thought process that is based exclusively on
ldquofunctionrdquo ie what something lsquodoesrsquo not what it is
Value Engineering
Value Engineering is where the value of all the components used in the construction of a
product from design to final delivery stage are completely analyzed and pursued
VALUE(P) = Desired performance
---------------------------
Overall Costs(C)
Value can be increased by either improving the Performance or reducing the cost

VALUE ENGINEERING BASICS
JOB PLANS
The basic framework for conducting a value study is the Job Plan Value Engineering is
a systematic approach and it has a well-considered job plan that needs to be adhered to
maximise the effectiveness of the technique A typical job plan is given below
Selection of the project and the team members
Collection of Information
Function identification and analysis
Creation idea generation
Evaluation of ideas
Investigation of alternative solution
Final recommendations and presentation
The above plans provide a systematic and orderly approach to conducting a study The
plan includes both analytical and creative phases Each phase has its rules that are
designed to increase the effectiveness of the phase

INFLUENCE OF SELECTION OF TIME ON VALUE ENGINEERING(VE) APPLICATION
PHASE VALUE ENGINEEING EMPHASIS
CONCEPT FORMULATION PHASE
VE studies during this phase are directed at Furnishing inputs needed to ensure the most
economical decisions to achieve the functions sought
achieving low total cost of ownership (rather than just low acquisition cost)
TENTATIVE DESIGN PHASE
VE studies during this phase add value by analysing and developing alternatives for the following
Essential requirements Technical characteristics Design tasks
FINAL DESIGN PHASE VE studies during this phase are limited to
Eliminating unnecessarily restrictive detail and eliminating items not necessary
Redesign effort at this stage cannot be economically accomplished due to the implementation costs involved
CONSTRUCTION MANUFACTURING PHASE
VE studies during this phase result in
Extension of an items life Reduced repair costs Savings in energy and other operating costs Reduction in the number of supply items in stockVE can be performed both internally and by the contractorvendor
Value Methodology (also called Value Engineering Value Analysis or Value
Management) is a powerful problem- solving tool that can reduce costs while
maintaining or improving performance and quality requirements It is a function-oriented
systematic team approach to providing value in a product or service
The value methodology helps organizations compete more effectively in local national
and
international markets by
-Decreasing costs
-Increasing profits
-Improving quality
-Expanding market share
-Saving time
-Solving problems
-Using resources more effectively
VALUE ANALYSIS amp VALUE ENGINEERING
Value analysis is systematic creative and organized approach amp to identify unnecessary
costValue engineering is a technique of application to eliminate unnecessary cost
Generally value analysis is based for cost values Unless otherwise is specified
Value Analysis is an effective tool for cost reduction and the results accomplished are far
greater It improves the effectiveness of work that has been conventionally performed as
it questions and probes into the very purpose design method of manufacture etc of the
product with a view to pinpointing unnecessary costs obvious and hidden which can be
eliminated without adversely affecting quality efficiency safety and other customer
features
VALUE AND VALUE ANALYSIS
Let us consider at this stage what is meant by ldquoValuersquo lsquoValuersquo is itself is some what
difficult to define It means different things to different people
Value Analysis
VA is an step by step approach to identify the functions of a product process system or
service to establish a monetary value for that function and then provide the desired
function
at an overall minimum cost without affecting any of the existing parameters like Quality
Maintainability Productivity Safety and other Performance characteristics
Also it is often confused with the cost and price of a product or service One way of
defining the value of an item is
Worth to you
Value = ------------------
Price you pay
This means that if you feel that you have your moneyrsquos worth then you have received
100 per cent value Which indicates that lsquoValuersquo has a subjective aspect for what is good
value for one person need not necessarily be so far another In general if for any function
or a product or a service you feel you are paying too much or it costs you more than you
think it should there is scope for improving its lsquovaluersquo into it This leads us on to another
useful way of looking at lsquovaluersquo Value is the least cost that can accomplish reliably a
function or a service This implies that in achieving reduced cost the quality and
performance of the item are maintained It follows therefore that value analysis is a
technique which builds ldquoValuersquo into an item Value can also be defined as that
combination of quality efficiency price and service which ensures the ultimate economy
and satisfaction of the purchaser Value Analysis can be understood as a technique which
helps everyone to determine this combination It can be seen therefore that several
components make up lsquoValuersquo There is value arising from the function or end use of an
item and from its ability to perform a useful function reliable There is the subjective
aspect of value in terms of esteem or prestige value or artistic value for example the
extra chrome 63 and styling used to sell automobiles or the neck-tie or diamond ring you
may wear Again there is the cost value made up of the material and labour costs
overheads and any other costs incurred in producing the item However in the popular
mind this is closely associated with esteem value as there is a mistaken belief that
because something costs more it is worth more Finally there is the resale or exchange
value which may be taken as the ability to part with money for possessing a particular
product In addition we have place value with regard to the usefulness of a product at a
particular place
VARIOUS VALUES CONSIDERED BY VALUE ANALYSEE
1) Huge or functional Value-
It is due to the characteristic quality attributes property of the product by virtue of
which the product performs intended function most satisfactorily with minimum
maintenance
2) Aesthetic Value-
It is due to characteristic attributes property quality because of which product becomes
attractive elegant looking creates sales appeal color shade style texture etc
3) Exchange Value-
It is in terms of the amount of any other commodity that can be obtained in exchange of
the commodity under consideration It depends on time and place
4) Esteem Value-
It is due to special characteristics some manufacturers enjoy customer goodwill and
historical prestige
5) Cost Value-
It is the total of all the costs incurred to manufacture a product ie Unnecessary cost due
to
sect Bad product design
sect Inefficient manufacturing method
sect Inefficient manufacturing processes
sect Lack of Standardization
sect Choose of wrong machine and tools
sect Bad Layout
sect Bad working conditions
sect Accidents to the worker
sect Machine breakdown
sect Bad quality Raw material
sect Lack of training to the workers
sect Excessive variety of products
sect Frequent changes in product design
sect Improper material handling
sect Defective packaging of product
sect Waiting
sect Searching
sect Bad house keeping etc

1048707 Identify and develop strategies to mitigate or avoid risks and the
associated costs
1048707 Identify opportunities which promote Context Sensitive Solutions
1048707 Validate projectrsquos scope need and purpose and baseline design
APPLICATION OF VALUE ANALYSIS
Value analysis can be applied universally ie to everything ndash materials methods
processes services etc where it is intended to bring about economics One should
naturally start with items where the maximum annual saving can be achieved This
immediately suggests that items whose total annual consumption in Rupees is high
should receive top priorities in the application of Value Analysis In the same manner
scarce materials imported materials or those difficult to obtain should also receive the
attention of the value analyst Bearing this in mind Value Analysis can be systematically
applied to categories of items such as those listed below in order to bring about
substantial cost reduction
1 Capital goods ndash plant equipment machinery tools and appliances
2 Raw and semi-processed material including fuel
3 Sub-contracted parts components sub-assemblies etc
4 Purchased parts components sub-assemblies etc
5 Maintenance repairs and operational items
6 Finishing items such as paints oils varnishes etc
7 Packing materials and packaging
8 Printing and Stationery items
9 Miscellaneous items of regular consumptions
10 Power water supply compressed air steam and other utilities
(services) and
11 Materials handling and transportation costs
As mentioned earlier items where the saving can be substantial should obviously
be taken up first Also items which are imported or difficult to obtain and monopoly
items should receive high priority
However even if no economy can be effected immediately by Value Analysis on any
particular item then usefulness of the technique should not be forgotten altogether The
item should be taken up again for value analysis after six months or a year the period
being dictated by the findings of the investigation New ideas may come to your mind at
some other time Also it should be noted that the conditions in the market keep on
changing fast and new materials new suppliers and new processes come into existence
rapidly as a result of phenomenal technological progress taking place at present A
frequent and systematic review of the items already value analyzed with advantage may
result in further economies
ORGANISATION FOR VALUE ANALYSIS
Value analysis is a staff function like for instance Industrial Engineering and should be
organized as much It should be directly under a high-ranking officer from the Senior
Management of an undertaking This is necessary because Value Analysis concerns all
departments and the analyst must have access to them and to their records performance
costs etc Depending upon the size of the undertaking and its scale of operations there
can be a Central Value Analysis Cell to co-ordinate the work of individual analysts
attached to the design purchase production and engineering departments Where there is
only one Value Analyst he may be attached to the Industrial Engineering Department
or to the Purchase Department
Value Analysis is essentially a team effort What particular items to be taken up for value
analysis and what action is to be taken is usually decided by a small committee
comprising representatives from the Design Production Purchase and Accounts
Departments Any other departmental representative can be coopted if and when
necessary
It is the Purchase Manager (or Material Manager) who has to initiate action convene
meetings at regular intervals and see that substantial results are obtained A large share
of the initial phase of the Value Analysis work will be done by the Purchase Manager or
by other departments at his instance It is his responsibility to seek the maximum value
when a product requirement comes upto the point of purchase It is his duty to challenge
wasteful and avoidable costs inherent in the items he is asked to buy It is therefore
inevitable that a large part of whatever Value Analysis work is done is initiated by the
Purchase Manager
WHEN VALUE ANALYSIS
A product goes through 3 stages (1) Developmental (2) Growth and (3) Maturity before
being out of date Consider now the design efforts put on a product At developmental
stages the design effort is the maximum At the growth stage the effort is much less and is
mainly modifications and changes At maturity stage hardly any design attention is
needed The value of the product slowly increases in development and growth stages as
more features are added and desired changes and modifications are effected At maturity
stage the value increases to peak and then slowly starts reduction because of competition
change of customer tastes and other factors till the product falls out and becomes out of
date It is this stage where value analysis can still enhance the value by cost reduction
and lengthen the Maturity period of a product Thus when the design effort is diverted to
other products it is the time for value analysis to be undertaken The success of value
analysis for one product of course be made use of in the design of other products by
development wing
DIFFERENCE BETWEEN VALUE ANLAYSIS AND VALUE ENGINEERING

It may change the present stage of the product The changes are executed
at the initial stages only

It is worked out mostly with help of knowledge It requires specific
technical knowledge
and experience
VALUE ANALYSIS JOB PLAN
Several versions of the VA Job Plan can be found in different literature Some give file
others six and yet many other seven phases It is the systematic approach which is more
important to achieve the desired objectives The phases of VA Job Plan are as follows
SELECTION amp ORIENTATION
ANALYSIS
RECORDING IDEAS
SPECULATION
INVESTIGATION
RECOMMENDATION
IMPLEMENTATION
1) SELECTION amp - to select those problems areas ORIENTATION where a potential for
net higher Savings is expected - use the common paretorsquos ABC analysis - general scope
restrictions and aims of the study is defined
2) ANALYSIS - to examine the data at a coordinated syndicate meeting - to appoint a
secretary to record the minutes - to apply the Tests for Value - to propose further actions
3) RECORDING IDEAS - the secretary writes clearly the minutes of the analysis
meeting
and circulates them to syndicate members - it includes the agenda for the next meeting
4) SPECULATION - to hold additional syndicate 64 meetings in order to discuss the
ideas analysed and any new information obtained - to speculate upon practical measures
for reducing costs and increasing value
5) INVESTIGATION - to investigate suggestions for reducing costs and to make them
practical and acceptable - to obtain definite prices and costs in order to estimate savings
accurately
6) RECOMMENDATION - recommended practical savings to management for
implementing - to present the recommendations as a comprehensive report - to appoint a
member to act as an implementation consultant
7) IMPLEMENTATION - to decide on future plans for the company for which the
authority of the management is needed - to implement the recommendations acceptable to
the management
The value of a function can be increased by four methods
1 Decrease the cost while ensuring the same level of performance
2 Enhance the performance at the same cost
3 Decrease the cost and increase the performance
4 Increase both performance and cost ensuring that performance increases more than
the increment in the cost
ORGANISATION FOR VALUE ANALYSIS
Value analysis is a staff function like for instance Industrial Engineering and should be
organized as much It should be directly under a high-ranking officer from the Senior
Management of an undertaking This is necessary because Value Analysis concerns all

is initiated by the Purchase Manager
VALUE ENGINEERING
Value engineering is the term applied to value analysis done the design and prototype
stage of a product The potentials of saving are a more in case value analysis is done at
design stage Other advantages is that any changes at this stage are less costly than to
effect the same at a latter stage when the production is in full swing There are a few
limitations however on value engineering work At the design and proto-type stage the
time is rather short since a company wants to put a new product in the market before any
of its competitors can set in and value engineering will have a very short time to apply
their techniques Evaluation of the value at this stage becomes difficult in absence of any
customer reaction and opinion
WHEN VALUE ANALYSIS
A product goes through 3 stages (1) Developmental (2) Growth and (3) Maturity before
being out of date Consider now the design efforts put on a product At developmental
stages the design effort is the maximum At the growth stage the effort is much less and is
mainly modifications and changes At maturity stage hardly any design attention is

CASE STUDY
ldquoCost Reduction of a product throughValue Analysis amp Value Engineeringrdquo
Introduction
The current business scenario is very demanding with a continuous demand from the
market forces to reduce the product price The pricing as demanded by the market forces
the businesses to reduce product development and manufacturing costs to remain
competitive Manufacturing costs of a product can be broadly categorized in the
following heads
bull Raw material
bull Labor
bull Process that is technology driven
Product engineers are constantly faced with the following challenges
bull Reduce production cost
bull Reduce the material cost
Value Analysis amp Value Engineering (VAVE) methods are very important and useful
in driving down the product cost which helps companies retain market share and sustain
their profitability
At QuEST we uncover those projects of our customer which have a good potential to
improve profits QuEST has a team of engineers who specialize in VAVE to achieve cost
reductions of products
A typical VAVE exercise could reduce the total cost of a product by 5-40 The typical
elements of a VAVE exercise are as follows
bull Information Understand the current state of the project and constraints requirements
bull Function Analysis Understand the project from a functional perspective what must
the project do rather than how the project is currently conceived The function describes
what something does and function analysis is the process where the team reviews the
projects functions to determine those that could be improved Function Analysis can be
enhanced through the use of a graphical mapping tool known as the Function Analysis
System Technique (FAST) FAST applies intuitive logic to test functions create a
common language for a team and test the validity of the functions in the project
bull Creative Generate a quantity of ideas related to other ways to perform the functions
bull Evaluation Reduce the quantity of ideas that have been identified to a short list of
ideas with the greatest potential to improve the project and meet the Value Engineering
study objective
bull Development Further analyze and develop the short list of ideas and develop those
with merit into value alternatives
bull Presentation Phase Implementation Present value alternatives to management team
and other project stakeholders or decision makers
5 Typical Flowchart
An example
The approach to a real life problem and the methodology followed by QuEST to reduce
the product cost is demonstrated through the following example
51 Background and Problem statement
One of the customers of QuEST is a leading manufacturer of industrial components for
control applications This unit is very popular in high end applications
The customer wanted to develop a unit that not only costs 25 less but whose
performance exceeds that of the existing product
52 Challenges
bull Redesign of parts considering minimum impact on existing tooling
bull Redesigned modules should enable field replacement
bull LogicSoftware compatibility with field units
bull Ease of assembly
bull Design must match existing housings and connectors
bull No modification of standardized parts in the product family
54 Value Engineering Study
QuEST team captured the detailed requirements of the project from the Voice of
Customer (VOC) during the kick off meeting It helped to identify areas where cost could
be reduced and which functions needed to be improved to provide competitive advantage
The requirements were listed and prioritized as primary and secondary These prioritized
ldquoNeeds and Wantsrdquo were ranked Quality Function Deployment (QFD) tool was used to
prioritize the ldquoHowrsquosrdquo that affected the ldquoNeeds and Wantsrdquo of the customer The
customer also actively participated in this exercise Vital few options were prioritized
from the trivial many Design requirement ranks were sorted in descending order and
those which addressed 70 of the requirements were selected Thus CTQs or
performance characteristics were identified and agreed upon with the customer The team
then carried out the lsquoABC analysisrsquo on the BOM Components with more than 80 of the
product cost were identified
CTQ (Critical to Quality)
Matches basic function and performance characteristics
One to one module replacement
Same Outer dimensions for the modules
LogicSoftware compatibility with field units
No modification in standardized parts in Product family
Design must match existing housings and connectors
Reduce the cost of direct material by 25 or more
Next the VAVE team laid down the Functions of each item of the product for Value
analysis
This enhanced the understanding of the product functionality This also helped to
understand the Form Fit amp Functions of each of the items amp sub-assemblies With this
study the VAVE team had divided the main project into many sub-projects with respect
to subassemblies to have diversified results for subassemblies and parts This function
diagram threw up many questions to the team which enabled them to come up with a
number of new ideas
bull How the Product is sized What design parameters were employed for this product
bull Focus on high cost components and challenge by asking ldquowhy do we need this part and
what value does it provide to our customerrdquo
bull How else we can designmake it
bull Understand design change impact on subassembly or overall product
bull System level appraisal is desirable to consider different methods or concepts for
delivering the same or better value
bull Component level assessment is lookedfor to consider alternate materials processes and
more efficient designs
bull One of the guiding principles of lean design is to ldquoeliminate or standardizerdquo Can a part
be combined with others and thereby be eliminated If not can it be made common with
other parts in the product
without compromising FFF (Form Fit amp Function) This typically provides quick savings
bull Identify and capture all cost reduction opportunities
The team applied the concept of Pugh Matrix for system amp component level Rankings
were discussed with team collated and analyzed for choosing the optimum concepts
Next FMEA was conducted on the selected concepts to further fine tune the results
Failure modes with high Risk Priority Number (RPN) were identified Failure modes
were prioritized and communicated to the designers to address these risks Alternate
solutions and improvement were discussed and finalized 3D solid modeling was done to
visualize the product It also helped to simulate the active and passive conditions of the
product Components were standardized to reduce the part count Simulation and testing
against the CTQs helped to optimize the product for performances Design calculations
were performed to verify the design for gears springs snaps in the plastic members etc
Also the DFMA was conducted on various aspects of the design amp CTQs A detailed
Differential Cost Analysis was conducted with the customer and their suppliers The
result showed significant cost reduction of each part of the product It was observed that
the costs were reduced mainly due to alternate materials usage the process and by
eliminationreplacement of a part by integrating with the adjacent one
Costs of direct material were compared for the original and new design A significant
38 of savings in direct material cost was realized by this project The team also
achieved a reduction of 34 in the part count This has resulted in many intangible
benefits like savings in procurement costs Inspection costs Inventory cost
transportation reduced variation reduced assembly costs amp Time etc
6 Conclusion
QuEST lsquoValue Engineering teamrsquo achieved 38 of savings in direct material cost and
reduced part count by 34 in this project Having a Paint brush does not make one a
painter While we strive to implement the different VAVE tools we realize that the years
of experience in product design amp development is very essential to achieve the desired
objective VAVE tools and techniques if applied properly with trained amp experienced
resources will provide an extremely powerful suite to improve productivity lower cost
improve quality and also shorten the time-to-market

CONCLUSION
Value analysis is a technique with immense possibilities and systematically employed it
can achieve great economies and increased efficiency Although good results have been
obtained in several individual cases in some industries only a large scale and systematic
application of this technique in all industries and in defence production can result in
substantial economies on a national scale
This valuable technique if systematically employed promises rich dividends and
among other things enables greater use of indigenous raw materials and equipment by
import substitution It is therefore of special significance to a developing country like
India which has adopted a programme of rapid industrialization in the face of paucity of
foreign exchange and other handicaps
No Company can take seriously Total Quality Management without operating a
formalized system of Value Analysis No business that wishes to become lean will ever
succeed if product designs remain unchanged because no amount of continuous
improvement in the manufacturing process can release the costs of a poor design or a
design that has not changed for many years
However poor product reviews or an informal process that is restricted to only to a
review of the design by the design department will yield only limited success in
eliminating lsquoavoidable costsrsquo These efforts will miss the many opportunities to make
manufacturing and assembly easier quicker less complex and less costly Thus margins
will not be improved significantly because only a small part of the total process has been
managed correctly As such this type of superficial activity will not generate increased
profit and the revenue stream that will be needed to finance new products and new
investments in technology A properly managed and effective VA process will easily
repay the time invested by managers over the life of the product and a truly effective
process will yield significant competitive advantage for companies that exploit it For
businesses that supply other organizations the ability to design and redesign products
opens the possibility of true meaningful profitable and long-term partnership with a
customer Each progressive step that secures a greater design responsibility for the
supplier will in parallel make the supplier increasingly more important to the
competitive advantage of the customer organization and will increase the benefits to both
companies In an environment where budgets are often reduced the market determines
the selling price of a product and consumers demand a greater variety of products VA is
one technique that companies cannot afford to ignore because for every day that the
technique is not employed is money that will leave the business forever Money that
cannot be recovered once the product has been sold
The benefits of a formalized and effective VA process are therefore many and include
some key sources of competitive advantage for any business including
bull Speed of getting an effective design into the market without problems and through
error-free manufacturing and assembly processes
bull Reliability and durability of the product in the market which enhances the reputation
of the product and the company
bull Low overall cost which enhances product margin and also releases finances within the
business as well as allowing the ability to engage in price competition
bull Enhanced quality and compliance with minimal costs of warranty that allows a
company to differentiate its products based this perceived quality (of use and esteem)
bull Differentiation by creating product designs as platforms which facilitate lsquolast
minutersquo or late configuration of the product to meet customer orders regional preferences
or any other geographical constraint (such as product laws of a certain region)
bull Finally the VA process satisfies the primary goal of any business ndash to make a profit
and survive
As a process VA is very robust and offers tangible financial and people-based benefits
The process eliminates unnecessary weight it removes unnecessary costs and importantly
it allows people to understand products processes and continuous improvement Very
few modern management techniques allow this form of participation and involvement
and even fewer have such a profound impact on the bottom line of the businessrsquos trading
accounts For companies that do not employ this technique there is one very frightening
thought that for every product that the company makes one or two may be bought by
competitors and subjected to value analysis Therefore these competitors can easily
recover the ground lost to any lsquobreakthroughrsquo new product with half the effort and half
the expense of starting from the beginning These competitors can also take the new
product and lsquostreamlinersquo it to offer maximum value at minimum cost thereby creating a
new product without any real expense This is perhaps the most frightening though of all

TENTATIVE DESIGN PHASE
VE studies during this phase add value by analysing and developing alternatives for the following
Essential requirements Technical characteristics Design tasks
FINAL DESIGN PHASE VE studies during this phase are limited to
Eliminating unnecessarily restrictive detail and eliminating items not necessary
Redesign effort at this stage cannot be economically accomplished due to the implementation costs involved
CONSTRUCTION MANUFACTURING PHASE
VE studies during this phase result in
Extension of an items life Reduced repair costs Savings in energy and other operating costs Reduction in the number of supply items in stockVE can be performed both internally and by the contractorvendor
Value Methodology (also called Value Engineering Value Analysis or Value
Management) is a powerful problem- solving tool that can reduce costs while
maintaining or improving performance and quality requirements It is a function-oriented
systematic team approach to providing value in a product or service
The value methodology helps organizations compete more effectively in local national
and
international markets by
-Decreasing costs
-Increasing profits
-Improving quality
-Expanding market share
-Saving time
-Solving problems
-Using resources more effectively
VALUE ANALYSIS amp VALUE ENGINEERING
Value analysis is systematic creative and organized approach amp to identify unnecessary
costValue engineering is a technique of application to eliminate unnecessary cost
Generally value analysis is based for cost values Unless otherwise is specified
Value Analysis is an effective tool for cost reduction and the results accomplished are far
greater It improves the effectiveness of work that has been conventionally performed as
it questions and probes into the very purpose design method of manufacture etc of the
product with a view to pinpointing unnecessary costs obvious and hidden which can be
eliminated without adversely affecting quality efficiency safety and other customer
features
VALUE AND VALUE ANALYSIS
Let us consider at this stage what is meant by ldquoValuersquo lsquoValuersquo is itself is some what
difficult to define It means different things to different people
Value Analysis
VA is an step by step approach to identify the functions of a product process system or
service to establish a monetary value for that function and then provide the desired
function
at an overall minimum cost without affecting any of the existing parameters like Quality
Maintainability Productivity Safety and other Performance characteristics
Also it is often confused with the cost and price of a product or service One way of
defining the value of an item is
Worth to you
Value = ------------------
Price you pay
This means that if you feel that you have your moneyrsquos worth then you have received
100 per cent value Which indicates that lsquoValuersquo has a subjective aspect for what is good
value for one person need not necessarily be so far another In general if for any function
or a product or a service you feel you are paying too much or it costs you more than you
think it should there is scope for improving its lsquovaluersquo into it This leads us on to another
useful way of looking at lsquovaluersquo Value is the least cost that can accomplish reliably a
function or a service This implies that in achieving reduced cost the quality and
performance of the item are maintained It follows therefore that value analysis is a
technique which builds ldquoValuersquo into an item Value can also be defined as that
combination of quality efficiency price and service which ensures the ultimate economy
and satisfaction of the purchaser Value Analysis can be understood as a technique which
helps everyone to determine this combination It can be seen therefore that several
components make up lsquoValuersquo There is value arising from the function or end use of an
item and from its ability to perform a useful function reliable There is the subjective
aspect of value in terms of esteem or prestige value or artistic value for example the
extra chrome 63 and styling used to sell automobiles or the neck-tie or diamond ring you
may wear Again there is the cost value made up of the material and labour costs
overheads and any other costs incurred in producing the item However in the popular
mind this is closely associated with esteem value as there is a mistaken belief that
because something costs more it is worth more Finally there is the resale or exchange
value which may be taken as the ability to part with money for possessing a particular
product In addition we have place value with regard to the usefulness of a product at a
particular place
VARIOUS VALUES CONSIDERED BY VALUE ANALYSEE
1) Huge or functional Value-
It is due to the characteristic quality attributes property of the product by virtue of
which the product performs intended function most satisfactorily with minimum
maintenance
2) Aesthetic Value-
It is due to characteristic attributes property quality because of which product becomes
attractive elegant looking creates sales appeal color shade style texture etc
3) Exchange Value-
It is in terms of the amount of any other commodity that can be obtained in exchange of
the commodity under consideration It depends on time and place
4) Esteem Value-
It is due to special characteristics some manufacturers enjoy customer goodwill and
historical prestige
5) Cost Value-
It is the total of all the costs incurred to manufacture a product ie Unnecessary cost due
to
sect Bad product design
sect Inefficient manufacturing method
sect Inefficient manufacturing processes
sect Lack of Standardization
sect Choose of wrong machine and tools
sect Bad Layout
sect Bad working conditions
sect Accidents to the worker
sect Machine breakdown
sect Bad quality Raw material
sect Lack of training to the workers
sect Excessive variety of products
sect Frequent changes in product design
sect Improper material handling
sect Defective packaging of product
sect Waiting
sect Searching
sect Bad house keeping etc
Benefits of Value Analysis
VA is an effective problem solving and quality assurance tool that can facilitate Caltrans
goals to maximize Safety Mobility Delivery Stewardship and Service VA studies
should be considered to
1048707 Meet or exceed standards and safety objectives
1048707 Foster a team approach to problem solving and project development
1048707 Improving a projectrsquos performance while maximizing quality
1048707 Identify and develop strategies to mitigate or avoid risks and the
associated costs
1048707 Identify opportunities which promote Context Sensitive Solutions
1048707 Validate projectrsquos scope need and purpose and baseline design
APPLICATION OF VALUE ANALYSIS
Value analysis can be applied universally ie to everything ndash materials methods
processes services etc where it is intended to bring about economics One should
naturally start with items where the maximum annual saving can be achieved This
immediately suggests that items whose total annual consumption in Rupees is high
should receive top priorities in the application of Value Analysis In the same manner
scarce materials imported materials or those difficult to obtain should also receive the
attention of the value analyst Bearing this in mind Value Analysis can be systematically
applied to categories of items such as those listed below in order to bring about
substantial cost reduction
1 Capital goods ndash plant equipment machinery tools and appliances
2 Raw and semi-processed material including fuel
3 Sub-contracted parts components sub-assemblies etc
4 Purchased parts components sub-assemblies etc
5 Maintenance repairs and operational items
6 Finishing items such as paints oils varnishes etc
7 Packing materials and packaging
8 Printing and Stationery items
9 Miscellaneous items of regular consumptions
10 Power water supply compressed air steam and other utilities
(services) and
11 Materials handling and transportation costs
As mentioned earlier items where the saving can be substantial should obviously
be taken up first Also items which are imported or difficult to obtain and monopoly
items should receive high priority
However even if no economy can be effected immediately by Value Analysis on any
particular item then usefulness of the technique should not be forgotten altogether The
item should be taken up again for value analysis after six months or a year the period
being dictated by the findings of the investigation New ideas may come to your mind at
some other time Also it should be noted that the conditions in the market keep on
changing fast and new materials new suppliers and new processes come into existence
rapidly as a result of phenomenal technological progress taking place at present A
frequent and systematic review of the items already value analyzed with advantage may
result in further economies
ORGANISATION FOR VALUE ANALYSIS
Value analysis is a staff function like for instance Industrial Engineering and should be
organized as much It should be directly under a high-ranking officer from the Senior
Management of an undertaking This is necessary because Value Analysis concerns all
departments and the analyst must have access to them and to their records performance
costs etc Depending upon the size of the undertaking and its scale of operations there
can be a Central Value Analysis Cell to co-ordinate the work of individual analysts
attached to the design purchase production and engineering departments Where there is
only one Value Analyst he may be attached to the Industrial Engineering Department
or to the Purchase Department
Value Analysis is essentially a team effort What particular items to be taken up for value
analysis and what action is to be taken is usually decided by a small committee
comprising representatives from the Design Production Purchase and Accounts
Departments Any other departmental representative can be coopted if and when
necessary
It is the Purchase Manager (or Material Manager) who has to initiate action convene
meetings at regular intervals and see that substantial results are obtained A large share
of the initial phase of the Value Analysis work will be done by the Purchase Manager or
by other departments at his instance It is his responsibility to seek the maximum value
when a product requirement comes upto the point of purchase It is his duty to challenge
wasteful and avoidable costs inherent in the items he is asked to buy It is therefore
inevitable that a large part of whatever Value Analysis work is done is initiated by the
Purchase Manager
WHEN VALUE ANALYSIS
A product goes through 3 stages (1) Developmental (2) Growth and (3) Maturity before
being out of date Consider now the design efforts put on a product At developmental
stages the design effort is the maximum At the growth stage the effort is much less and is
mainly modifications and changes At maturity stage hardly any design attention is
needed The value of the product slowly increases in development and growth stages as
more features are added and desired changes and modifications are effected At maturity
stage the value increases to peak and then slowly starts reduction because of competition
change of customer tastes and other factors till the product falls out and becomes out of
date It is this stage where value analysis can still enhance the value by cost reduction
and lengthen the Maturity period of a product Thus when the design effort is diverted to
other products it is the time for value analysis to be undertaken The success of value
analysis for one product of course be made use of in the design of other products by
development wing
DIFFERENCE BETWEEN VALUE ANLAYSIS AND VALUE ENGINEERING

technical knowledge
and experience
VALUE ANALYSIS JOB PLAN
Several versions of the VA Job Plan can be found in different literature Some give file
others six and yet many other seven phases It is the systematic approach which is more
important to achieve the desired objectives The phases of VA Job Plan are as follows
SELECTION amp ORIENTATION
ANALYSIS
RECORDING IDEAS
SPECULATION
INVESTIGATION
RECOMMENDATION
IMPLEMENTATION
1) SELECTION amp - to select those problems areas ORIENTATION where a potential for
net higher Savings is expected - use the common paretorsquos ABC analysis - general scope
restrictions and aims of the study is defined
2) ANALYSIS - to examine the data at a coordinated syndicate meeting - to appoint a
secretary to record the minutes - to apply the Tests for Value - to propose further actions
3) RECORDING IDEAS - the secretary writes clearly the minutes of the analysis
meeting
and circulates them to syndicate members - it includes the agenda for the next meeting
4) SPECULATION - to hold additional syndicate 64 meetings in order to discuss the
ideas analysed and any new information obtained - to speculate upon practical measures
for reducing costs and increasing value
5) INVESTIGATION - to investigate suggestions for reducing costs and to make them
practical and acceptable - to obtain definite prices and costs in order to estimate savings
accurately
6) RECOMMENDATION - recommended practical savings to management for
implementing - to present the recommendations as a comprehensive report - to appoint a
member to act as an implementation consultant
7) IMPLEMENTATION - to decide on future plans for the company for which the
authority of the management is needed - to implement the recommendations acceptable to
the management
The value of a function can be increased by four methods
1 Decrease the cost while ensuring the same level of performance
2 Enhance the performance at the same cost
3 Decrease the cost and increase the performance
4 Increase both performance and cost ensuring that performance increases more than
the increment in the cost
ORGANISATION FOR VALUE ANALYSIS
Value analysis is a staff function like for instance Industrial Engineering and should be
organized as much It should be directly under a high-ranking officer from the Senior

is initiated by the Purchase Manager
VALUE ENGINEERING
Value engineering is the term applied to value analysis done the design and prototype
stage of a product The potentials of saving are a more in case value analysis is done at
design stage Other advantages is that any changes at this stage are less costly than to
effect the same at a latter stage when the production is in full swing There are a few
limitations however on value engineering work At the design and proto-type stage the
time is rather short since a company wants to put a new product in the market before any
of its competitors can set in and value engineering will have a very short time to apply
their techniques Evaluation of the value at this stage becomes difficult in absence of any
customer reaction and opinion
WHEN VALUE ANALYSIS
A product goes through 3 stages (1) Developmental (2) Growth and (3) Maturity before
being out of date Consider now the design efforts put on a product At developmental
stages the design effort is the maximum At the growth stage the effort is much less and is

CASE STUDY
ldquoCost Reduction of a product throughValue Analysis amp Value Engineeringrdquo
Introduction
The current business scenario is very demanding with a continuous demand from the
market forces to reduce the product price The pricing as demanded by the market forces
the businesses to reduce product development and manufacturing costs to remain
competitive Manufacturing costs of a product can be broadly categorized in the
following heads
bull Raw material
bull Labor
bull Process that is technology driven
Product engineers are constantly faced with the following challenges
bull Reduce production cost
bull Reduce the material cost
Value Analysis amp Value Engineering (VAVE) methods are very important and useful
in driving down the product cost which helps companies retain market share and sustain
their profitability
At QuEST we uncover those projects of our customer which have a good potential to
improve profits QuEST has a team of engineers who specialize in VAVE to achieve cost
reductions of products
A typical VAVE exercise could reduce the total cost of a product by 5-40 The typical
elements of a VAVE exercise are as follows
bull Information Understand the current state of the project and constraints requirements
bull Function Analysis Understand the project from a functional perspective what must
the project do rather than how the project is currently conceived The function describes
what something does and function analysis is the process where the team reviews the
projects functions to determine those that could be improved Function Analysis can be
enhanced through the use of a graphical mapping tool known as the Function Analysis
System Technique (FAST) FAST applies intuitive logic to test functions create a
common language for a team and test the validity of the functions in the project
bull Creative Generate a quantity of ideas related to other ways to perform the functions
bull Evaluation Reduce the quantity of ideas that have been identified to a short list of
ideas with the greatest potential to improve the project and meet the Value Engineering
study objective
bull Development Further analyze and develop the short list of ideas and develop those
with merit into value alternatives
bull Presentation Phase Implementation Present value alternatives to management team
and other project stakeholders or decision makers
5 Typical Flowchart
An example
The approach to a real life problem and the methodology followed by QuEST to reduce
the product cost is demonstrated through the following example
51 Background and Problem statement
One of the customers of QuEST is a leading manufacturer of industrial components for
control applications This unit is very popular in high end applications
The customer wanted to develop a unit that not only costs 25 less but whose
performance exceeds that of the existing product
52 Challenges
bull Redesign of parts considering minimum impact on existing tooling
bull Redesigned modules should enable field replacement
bull LogicSoftware compatibility with field units
bull Ease of assembly
bull Design must match existing housings and connectors
bull No modification of standardized parts in the product family
54 Value Engineering Study
QuEST team captured the detailed requirements of the project from the Voice of
Customer (VOC) during the kick off meeting It helped to identify areas where cost could
be reduced and which functions needed to be improved to provide competitive advantage
The requirements were listed and prioritized as primary and secondary These prioritized
ldquoNeeds and Wantsrdquo were ranked Quality Function Deployment (QFD) tool was used to
prioritize the ldquoHowrsquosrdquo that affected the ldquoNeeds and Wantsrdquo of the customer The
customer also actively participated in this exercise Vital few options were prioritized
from the trivial many Design requirement ranks were sorted in descending order and
those which addressed 70 of the requirements were selected Thus CTQs or
performance characteristics were identified and agreed upon with the customer The team
then carried out the lsquoABC analysisrsquo on the BOM Components with more than 80 of the
product cost were identified
CTQ (Critical to Quality)
Matches basic function and performance characteristics
One to one module replacement
Same Outer dimensions for the modules
LogicSoftware compatibility with field units
No modification in standardized parts in Product family
Design must match existing housings and connectors
Reduce the cost of direct material by 25 or more
Next the VAVE team laid down the Functions of each item of the product for Value
analysis
This enhanced the understanding of the product functionality This also helped to
understand the Form Fit amp Functions of each of the items amp sub-assemblies With this
study the VAVE team had divided the main project into many sub-projects with respect
to subassemblies to have diversified results for subassemblies and parts This function
diagram threw up many questions to the team which enabled them to come up with a
number of new ideas
bull How the Product is sized What design parameters were employed for this product
bull Focus on high cost components and challenge by asking ldquowhy do we need this part and
what value does it provide to our customerrdquo
bull How else we can designmake it
bull Understand design change impact on subassembly or overall product
bull System level appraisal is desirable to consider different methods or concepts for
delivering the same or better value
bull Component level assessment is lookedfor to consider alternate materials processes and
more efficient designs
bull One of the guiding principles of lean design is to ldquoeliminate or standardizerdquo Can a part
be combined with others and thereby be eliminated If not can it be made common with
other parts in the product
without compromising FFF (Form Fit amp Function) This typically provides quick savings
bull Identify and capture all cost reduction opportunities
The team applied the concept of Pugh Matrix for system amp component level Rankings
were discussed with team collated and analyzed for choosing the optimum concepts
Next FMEA was conducted on the selected concepts to further fine tune the results
Failure modes with high Risk Priority Number (RPN) were identified Failure modes
were prioritized and communicated to the designers to address these risks Alternate
solutions and improvement were discussed and finalized 3D solid modeling was done to
visualize the product It also helped to simulate the active and passive conditions of the
product Components were standardized to reduce the part count Simulation and testing
against the CTQs helped to optimize the product for performances Design calculations
were performed to verify the design for gears springs snaps in the plastic members etc
Also the DFMA was conducted on various aspects of the design amp CTQs A detailed
Differential Cost Analysis was conducted with the customer and their suppliers The
result showed significant cost reduction of each part of the product It was observed that
the costs were reduced mainly due to alternate materials usage the process and by
eliminationreplacement of a part by integrating with the adjacent one
Costs of direct material were compared for the original and new design A significant
38 of savings in direct material cost was realized by this project The team also
achieved a reduction of 34 in the part count This has resulted in many intangible
benefits like savings in procurement costs Inspection costs Inventory cost
transportation reduced variation reduced assembly costs amp Time etc
6 Conclusion
QuEST lsquoValue Engineering teamrsquo achieved 38 of savings in direct material cost and
reduced part count by 34 in this project Having a Paint brush does not make one a
painter While we strive to implement the different VAVE tools we realize that the years
of experience in product design amp development is very essential to achieve the desired
objective VAVE tools and techniques if applied properly with trained amp experienced
resources will provide an extremely powerful suite to improve productivity lower cost
improve quality and also shorten the time-to-market

CONCLUSION
Value analysis is a technique with immense possibilities and systematically employed it
can achieve great economies and increased efficiency Although good results have been
obtained in several individual cases in some industries only a large scale and systematic
application of this technique in all industries and in defence production can result in
substantial economies on a national scale
This valuable technique if systematically employed promises rich dividends and
among other things enables greater use of indigenous raw materials and equipment by
import substitution It is therefore of special significance to a developing country like
India which has adopted a programme of rapid industrialization in the face of paucity of
foreign exchange and other handicaps
No Company can take seriously Total Quality Management without operating a
formalized system of Value Analysis No business that wishes to become lean will ever
succeed if product designs remain unchanged because no amount of continuous
improvement in the manufacturing process can release the costs of a poor design or a
design that has not changed for many years
However poor product reviews or an informal process that is restricted to only to a
review of the design by the design department will yield only limited success in
eliminating lsquoavoidable costsrsquo These efforts will miss the many opportunities to make
manufacturing and assembly easier quicker less complex and less costly Thus margins
will not be improved significantly because only a small part of the total process has been
managed correctly As such this type of superficial activity will not generate increased
profit and the revenue stream that will be needed to finance new products and new
investments in technology A properly managed and effective VA process will easily
repay the time invested by managers over the life of the product and a truly effective
process will yield significant competitive advantage for companies that exploit it For
businesses that supply other organizations the ability to design and redesign products
opens the possibility of true meaningful profitable and long-term partnership with a
customer Each progressive step that secures a greater design responsibility for the
supplier will in parallel make the supplier increasingly more important to the
competitive advantage of the customer organization and will increase the benefits to both
companies In an environment where budgets are often reduced the market determines
the selling price of a product and consumers demand a greater variety of products VA is
one technique that companies cannot afford to ignore because for every day that the
technique is not employed is money that will leave the business forever Money that
cannot be recovered once the product has been sold
The benefits of a formalized and effective VA process are therefore many and include
some key sources of competitive advantage for any business including
bull Speed of getting an effective design into the market without problems and through
error-free manufacturing and assembly processes
bull Reliability and durability of the product in the market which enhances the reputation
of the product and the company
bull Low overall cost which enhances product margin and also releases finances within the
business as well as allowing the ability to engage in price competition
bull Enhanced quality and compliance with minimal costs of warranty that allows a
company to differentiate its products based this perceived quality (of use and esteem)
bull Differentiation by creating product designs as platforms which facilitate lsquolast
minutersquo or late configuration of the product to meet customer orders regional preferences
or any other geographical constraint (such as product laws of a certain region)
bull Finally the VA process satisfies the primary goal of any business ndash to make a profit
and survive
As a process VA is very robust and offers tangible financial and people-based benefits
The process eliminates unnecessary weight it removes unnecessary costs and importantly
it allows people to understand products processes and continuous improvement Very
few modern management techniques allow this form of participation and involvement
and even fewer have such a profound impact on the bottom line of the businessrsquos trading
accounts For companies that do not employ this technique there is one very frightening
thought that for every product that the company makes one or two may be bought by
competitors and subjected to value analysis Therefore these competitors can easily
recover the ground lost to any lsquobreakthroughrsquo new product with half the effort and half
the expense of starting from the beginning These competitors can also take the new
product and lsquostreamlinersquo it to offer maximum value at minimum cost thereby creating a
new product without any real expense This is perhaps the most frightening though of all

Value Methodology (also called Value Engineering Value Analysis or Value
Management) is a powerful problem- solving tool that can reduce costs while
maintaining or improving performance and quality requirements It is a function-oriented
systematic team approach to providing value in a product or service
The value methodology helps organizations compete more effectively in local national
and
international markets by
-Decreasing costs
-Increasing profits
-Improving quality
-Expanding market share
-Saving time
-Solving problems
-Using resources more effectively
VALUE ANALYSIS amp VALUE ENGINEERING
Value analysis is systematic creative and organized approach amp to identify unnecessary
costValue engineering is a technique of application to eliminate unnecessary cost
Generally value analysis is based for cost values Unless otherwise is specified
Value Analysis is an effective tool for cost reduction and the results accomplished are far
greater It improves the effectiveness of work that has been conventionally performed as
it questions and probes into the very purpose design method of manufacture etc of the
product with a view to pinpointing unnecessary costs obvious and hidden which can be
eliminated without adversely affecting quality efficiency safety and other customer
features
VALUE AND VALUE ANALYSIS
Let us consider at this stage what is meant by ldquoValuersquo lsquoValuersquo is itself is some what
difficult to define It means different things to different people
Value Analysis
VA is an step by step approach to identify the functions of a product process system or
service to establish a monetary value for that function and then provide the desired
function
at an overall minimum cost without affecting any of the existing parameters like Quality
Maintainability Productivity Safety and other Performance characteristics
Also it is often confused with the cost and price of a product or service One way of
defining the value of an item is
Worth to you
Value = ------------------
Price you pay
This means that if you feel that you have your moneyrsquos worth then you have received
100 per cent value Which indicates that lsquoValuersquo has a subjective aspect for what is good
value for one person need not necessarily be so far another In general if for any function
or a product or a service you feel you are paying too much or it costs you more than you
think it should there is scope for improving its lsquovaluersquo into it This leads us on to another
useful way of looking at lsquovaluersquo Value is the least cost that can accomplish reliably a
function or a service This implies that in achieving reduced cost the quality and
performance of the item are maintained It follows therefore that value analysis is a
technique which builds ldquoValuersquo into an item Value can also be defined as that
combination of quality efficiency price and service which ensures the ultimate economy
and satisfaction of the purchaser Value Analysis can be understood as a technique which
helps everyone to determine this combination It can be seen therefore that several
components make up lsquoValuersquo There is value arising from the function or end use of an
item and from its ability to perform a useful function reliable There is the subjective
aspect of value in terms of esteem or prestige value or artistic value for example the
extra chrome 63 and styling used to sell automobiles or the neck-tie or diamond ring you
may wear Again there is the cost value made up of the material and labour costs
overheads and any other costs incurred in producing the item However in the popular
mind this is closely associated with esteem value as there is a mistaken belief that
because something costs more it is worth more Finally there is the resale or exchange
value which may be taken as the ability to part with money for possessing a particular
product In addition we have place value with regard to the usefulness of a product at a
particular place
VARIOUS VALUES CONSIDERED BY VALUE ANALYSEE
1) Huge or functional Value-
It is due to the characteristic quality attributes property of the product by virtue of
which the product performs intended function most satisfactorily with minimum
maintenance
2) Aesthetic Value-
It is due to characteristic attributes property quality because of which product becomes
attractive elegant looking creates sales appeal color shade style texture etc
3) Exchange Value-
It is in terms of the amount of any other commodity that can be obtained in exchange of
the commodity under consideration It depends on time and place
4) Esteem Value-
It is due to special characteristics some manufacturers enjoy customer goodwill and
historical prestige
5) Cost Value-
It is the total of all the costs incurred to manufacture a product ie Unnecessary cost due
to
sect Bad product design

APPLICATION OF VALUE ANALYSIS
Value analysis can be applied universally ie to everything ndash materials methods
processes services etc where it is intended to bring about economics One should
naturally start with items where the maximum annual saving can be achieved This
immediately suggests that items whose total annual consumption in Rupees is high
should receive top priorities in the application of Value Analysis In the same manner
scarce materials imported materials or those difficult to obtain should also receive the
attention of the value analyst Bearing this in mind Value Analysis can be systematically
applied to categories of items such as those listed below in order to bring about
substantial cost reduction
1 Capital goods ndash plant equipment machinery tools and appliances
2 Raw and semi-processed material including fuel
3 Sub-contracted parts components sub-assemblies etc
4 Purchased parts components sub-assemblies etc
5 Maintenance repairs and operational items
6 Finishing items such as paints oils varnishes etc
7 Packing materials and packaging
8 Printing and Stationery items
9 Miscellaneous items of regular consumptions
10 Power water supply compressed air steam and other utilities
(services) and
11 Materials handling and transportation costs
As mentioned earlier items where the saving can be substantial should obviously
be taken up first Also items which are imported or difficult to obtain and monopoly
items should receive high priority
However even if no economy can be effected immediately by Value Analysis on any
particular item then usefulness of the technique should not be forgotten altogether The
item should be taken up again for value analysis after six months or a year the period
being dictated by the findings of the investigation New ideas may come to your mind at
some other time Also it should be noted that the conditions in the market keep on
changing fast and new materials new suppliers and new processes come into existence
rapidly as a result of phenomenal technological progress taking place at present A
frequent and systematic review of the items already value analyzed with advantage may
result in further economies
ORGANISATION FOR VALUE ANALYSIS
Value analysis is a staff function like for instance Industrial Engineering and should be
organized as much It should be directly under a high-ranking officer from the Senior
Management of an undertaking This is necessary because Value Analysis concerns all
departments and the analyst must have access to them and to their records performance
costs etc Depending upon the size of the undertaking and its scale of operations there
can be a Central Value Analysis Cell to co-ordinate the work of individual analysts
attached to the design purchase production and engineering departments Where there is
only one Value Analyst he may be attached to the Industrial Engineering Department
or to the Purchase Department
Value Analysis is essentially a team effort What particular items to be taken up for value
analysis and what action is to be taken is usually decided by a small committee
comprising representatives from the Design Production Purchase and Accounts
Departments Any other departmental representative can be coopted if and when
necessary
It is the Purchase Manager (or Material Manager) who has to initiate action convene
meetings at regular intervals and see that substantial results are obtained A large share
of the initial phase of the Value Analysis work will be done by the Purchase Manager or
by other departments at his instance It is his responsibility to seek the maximum value
when a product requirement comes upto the point of purchase It is his duty to challenge
wasteful and avoidable costs inherent in the items he is asked to buy It is therefore
inevitable that a large part of whatever Value Analysis work is done is initiated by the
Purchase Manager
WHEN VALUE ANALYSIS
A product goes through 3 stages (1) Developmental (2) Growth and (3) Maturity before
being out of date Consider now the design efforts put on a product At developmental
stages the design effort is the maximum At the growth stage the effort is much less and is
mainly modifications and changes At maturity stage hardly any design attention is
needed The value of the product slowly increases in development and growth stages as
more features are added and desired changes and modifications are effected At maturity
stage the value increases to peak and then slowly starts reduction because of competition
change of customer tastes and other factors till the product falls out and becomes out of
date It is this stage where value analysis can still enhance the value by cost reduction
and lengthen the Maturity period of a product Thus when the design effort is diverted to
other products it is the time for value analysis to be undertaken The success of value
analysis for one product of course be made use of in the design of other products by
development wing

VALUE ANALYSIS JOB PLAN
Several versions of the VA Job Plan can be found in different literature Some give file
others six and yet many other seven phases It is the systematic approach which is more
important to achieve the desired objectives The phases of VA Job Plan are as follows
SELECTION amp ORIENTATION
ANALYSIS
RECORDING IDEAS
SPECULATION
INVESTIGATION
RECOMMENDATION
IMPLEMENTATION
1) SELECTION amp - to select those problems areas ORIENTATION where a potential for
net higher Savings is expected - use the common paretorsquos ABC analysis - general scope
restrictions and aims of the study is defined
2) ANALYSIS - to examine the data at a coordinated syndicate meeting - to appoint a
secretary to record the minutes - to apply the Tests for Value - to propose further actions
3) RECORDING IDEAS - the secretary writes clearly the minutes of the analysis
meeting
and circulates them to syndicate members - it includes the agenda for the next meeting
4) SPECULATION - to hold additional syndicate 64 meetings in order to discuss the
ideas analysed and any new information obtained - to speculate upon practical measures
for reducing costs and increasing value
5) INVESTIGATION - to investigate suggestions for reducing costs and to make them
practical and acceptable - to obtain definite prices and costs in order to estimate savings
accurately
6) RECOMMENDATION - recommended practical savings to management for
implementing - to present the recommendations as a comprehensive report - to appoint a
member to act as an implementation consultant
7) IMPLEMENTATION - to decide on future plans for the company for which the
authority of the management is needed - to implement the recommendations acceptable to
the management
The value of a function can be increased by four methods
1 Decrease the cost while ensuring the same level of performance
2 Enhance the performance at the same cost
3 Decrease the cost and increase the performance
4 Increase both performance and cost ensuring that performance increases more than
the increment in the cost

VALUE ENGINEERING
Value engineering is the term applied to value analysis done the design and prototype
stage of a product The potentials of saving are a more in case value analysis is done at
design stage Other advantages is that any changes at this stage are less costly than to
effect the same at a latter stage when the production is in full swing There are a few
limitations however on value engineering work At the design and proto-type stage the
time is rather short since a company wants to put a new product in the market before any
of its competitors can set in and value engineering will have a very short time to apply
their techniques Evaluation of the value at this stage becomes difficult in absence of any
customer reaction and opinion
WHEN VALUE ANALYSIS
A product goes through 3 stages (1) Developmental (2) Growth and (3) Maturity before
being out of date Consider now the design efforts put on a product At developmental
stages the design effort is the maximum At the growth stage the effort is much less and is

CASE STUDY
ldquoCost Reduction of a product throughValue Analysis amp Value Engineeringrdquo
Introduction
The current business scenario is very demanding with a continuous demand from the
market forces to reduce the product price The pricing as demanded by the market forces
the businesses to reduce product development and manufacturing costs to remain
competitive Manufacturing costs of a product can be broadly categorized in the
following heads
bull Raw material
bull Labor
bull Process that is technology driven
Product engineers are constantly faced with the following challenges
bull Reduce production cost
bull Reduce the material cost
Value Analysis amp Value Engineering (VAVE) methods are very important and useful
in driving down the product cost which helps companies retain market share and sustain
their profitability
At QuEST we uncover those projects of our customer which have a good potential to
improve profits QuEST has a team of engineers who specialize in VAVE to achieve cost
reductions of products
A typical VAVE exercise could reduce the total cost of a product by 5-40 The typical
elements of a VAVE exercise are as follows
bull Information Understand the current state of the project and constraints requirements
bull Function Analysis Understand the project from a functional perspective what must
the project do rather than how the project is currently conceived The function describes
what something does and function analysis is the process where the team reviews the
projects functions to determine those that could be improved Function Analysis can be
enhanced through the use of a graphical mapping tool known as the Function Analysis
System Technique (FAST) FAST applies intuitive logic to test functions create a
common language for a team and test the validity of the functions in the project
bull Creative Generate a quantity of ideas related to other ways to perform the functions
bull Evaluation Reduce the quantity of ideas that have been identified to a short list of
ideas with the greatest potential to improve the project and meet the Value Engineering
study objective
bull Development Further analyze and develop the short list of ideas and develop those
with merit into value alternatives
bull Presentation Phase Implementation Present value alternatives to management team
and other project stakeholders or decision makers
5 Typical Flowchart
An example
The approach to a real life problem and the methodology followed by QuEST to reduce
the product cost is demonstrated through the following example
51 Background and Problem statement
One of the customers of QuEST is a leading manufacturer of industrial components for
control applications This unit is very popular in high end applications
The customer wanted to develop a unit that not only costs 25 less but whose
performance exceeds that of the existing product
52 Challenges
bull Redesign of parts considering minimum impact on existing tooling
bull Redesigned modules should enable field replacement
bull LogicSoftware compatibility with field units
bull Ease of assembly
bull Design must match existing housings and connectors
bull No modification of standardized parts in the product family
54 Value Engineering Study
QuEST team captured the detailed requirements of the project from the Voice of
Customer (VOC) during the kick off meeting It helped to identify areas where cost could
be reduced and which functions needed to be improved to provide competitive advantage
The requirements were listed and prioritized as primary and secondary These prioritized
ldquoNeeds and Wantsrdquo were ranked Quality Function Deployment (QFD) tool was used to
prioritize the ldquoHowrsquosrdquo that affected the ldquoNeeds and Wantsrdquo of the customer The
customer also actively participated in this exercise Vital few options were prioritized
from the trivial many Design requirement ranks were sorted in descending order and
those which addressed 70 of the requirements were selected Thus CTQs or
performance characteristics were identified and agreed upon with the customer The team
then carried out the lsquoABC analysisrsquo on the BOM Components with more than 80 of the
product cost were identified
CTQ (Critical to Quality)
Matches basic function and performance characteristics
One to one module replacement
Same Outer dimensions for the modules
LogicSoftware compatibility with field units
No modification in standardized parts in Product family
Design must match existing housings and connectors
Reduce the cost of direct material by 25 or more
Next the VAVE team laid down the Functions of each item of the product for Value
analysis
This enhanced the understanding of the product functionality This also helped to
understand the Form Fit amp Functions of each of the items amp sub-assemblies With this
study the VAVE team had divided the main project into many sub-projects with respect
to subassemblies to have diversified results for subassemblies and parts This function
diagram threw up many questions to the team which enabled them to come up with a
number of new ideas
bull How the Product is sized What design parameters were employed for this product
bull Focus on high cost components and challenge by asking ldquowhy do we need this part and
what value does it provide to our customerrdquo
bull How else we can designmake it
bull Understand design change impact on subassembly or overall product
bull System level appraisal is desirable to consider different methods or concepts for
delivering the same or better value
bull Component level assessment is lookedfor to consider alternate materials processes and
more efficient designs
bull One of the guiding principles of lean design is to ldquoeliminate or standardizerdquo Can a part
be combined with others and thereby be eliminated If not can it be made common with
other parts in the product
without compromising FFF (Form Fit amp Function) This typically provides quick savings
bull Identify and capture all cost reduction opportunities
The team applied the concept of Pugh Matrix for system amp component level Rankings
were discussed with team collated and analyzed for choosing the optimum concepts
Next FMEA was conducted on the selected concepts to further fine tune the results
Failure modes with high Risk Priority Number (RPN) were identified Failure modes
were prioritized and communicated to the designers to address these risks Alternate
solutions and improvement were discussed and finalized 3D solid modeling was done to
visualize the product It also helped to simulate the active and passive conditions of the
product Components were standardized to reduce the part count Simulation and testing
against the CTQs helped to optimize the product for performances Design calculations
were performed to verify the design for gears springs snaps in the plastic members etc
Also the DFMA was conducted on various aspects of the design amp CTQs A detailed
Differential Cost Analysis was conducted with the customer and their suppliers The
result showed significant cost reduction of each part of the product It was observed that
the costs were reduced mainly due to alternate materials usage the process and by
eliminationreplacement of a part by integrating with the adjacent one
Costs of direct material were compared for the original and new design A significant
38 of savings in direct material cost was realized by this project The team also
achieved a reduction of 34 in the part count This has resulted in many intangible
benefits like savings in procurement costs Inspection costs Inventory cost
transportation reduced variation reduced assembly costs amp Time etc
6 Conclusion
QuEST lsquoValue Engineering teamrsquo achieved 38 of savings in direct material cost and
reduced part count by 34 in this project Having a Paint brush does not make one a
painter While we strive to implement the different VAVE tools we realize that the years
of experience in product design amp development is very essential to achieve the desired
objective VAVE tools and techniques if applied properly with trained amp experienced
resources will provide an extremely powerful suite to improve productivity lower cost
improve quality and also shorten the time-to-market

CONCLUSION
Value analysis is a technique with immense possibilities and systematically employed it
can achieve great economies and increased efficiency Although good results have been
obtained in several individual cases in some industries only a large scale and systematic
application of this technique in all industries and in defence production can result in
substantial economies on a national scale
This valuable technique if systematically employed promises rich dividends and
among other things enables greater use of indigenous raw materials and equipment by
import substitution It is therefore of special significance to a developing country like
India which has adopted a programme of rapid industrialization in the face of paucity of
foreign exchange and other handicaps
No Company can take seriously Total Quality Management without operating a
formalized system of Value Analysis No business that wishes to become lean will ever
succeed if product designs remain unchanged because no amount of continuous
improvement in the manufacturing process can release the costs of a poor design or a
design that has not changed for many years
However poor product reviews or an informal process that is restricted to only to a
review of the design by the design department will yield only limited success in
eliminating lsquoavoidable costsrsquo These efforts will miss the many opportunities to make
manufacturing and assembly easier quicker less complex and less costly Thus margins
will not be improved significantly because only a small part of the total process has been
managed correctly As such this type of superficial activity will not generate increased
profit and the revenue stream that will be needed to finance new products and new
investments in technology A properly managed and effective VA process will easily
repay the time invested by managers over the life of the product and a truly effective
process will yield significant competitive advantage for companies that exploit it For
businesses that supply other organizations the ability to design and redesign products
opens the possibility of true meaningful profitable and long-term partnership with a
customer Each progressive step that secures a greater design responsibility for the
supplier will in parallel make the supplier increasingly more important to the
competitive advantage of the customer organization and will increase the benefits to both
companies In an environment where budgets are often reduced the market determines
the selling price of a product and consumers demand a greater variety of products VA is
one technique that companies cannot afford to ignore because for every day that the
technique is not employed is money that will leave the business forever Money that
cannot be recovered once the product has been sold
The benefits of a formalized and effective VA process are therefore many and include
some key sources of competitive advantage for any business including
bull Speed of getting an effective design into the market without problems and through
error-free manufacturing and assembly processes
bull Reliability and durability of the product in the market which enhances the reputation
of the product and the company
bull Low overall cost which enhances product margin and also releases finances within the
business as well as allowing the ability to engage in price competition
bull Enhanced quality and compliance with minimal costs of warranty that allows a
company to differentiate its products based this perceived quality (of use and esteem)
bull Differentiation by creating product designs as platforms which facilitate lsquolast
minutersquo or late configuration of the product to meet customer orders regional preferences
or any other geographical constraint (such as product laws of a certain region)
bull Finally the VA process satisfies the primary goal of any business ndash to make a profit
and survive
As a process VA is very robust and offers tangible financial and people-based benefits
The process eliminates unnecessary weight it removes unnecessary costs and importantly
it allows people to understand products processes and continuous improvement Very
few modern management techniques allow this form of participation and involvement
and even fewer have such a profound impact on the bottom line of the businessrsquos trading
accounts For companies that do not employ this technique there is one very frightening
thought that for every product that the company makes one or two may be bought by
competitors and subjected to value analysis Therefore these competitors can easily
recover the ground lost to any lsquobreakthroughrsquo new product with half the effort and half
the expense of starting from the beginning These competitors can also take the new
product and lsquostreamlinersquo it to offer maximum value at minimum cost thereby creating a
new product without any real expense This is perhaps the most frightening though of all

VALUE ENGINEERING BASICS
JOB PLANS
The basic framework for conducting a value study is the Job Plan Value Engineering is
a systematic approach and it has a well-considered job plan that needs to be adhered to
maximise the effectiveness of the technique A typical job plan is given below
Selection of the project and the team members
Collection of Information
Function identification and analysis
Creation idea generation
Evaluation of ideas
Investigation of alternative solution
Final recommendations and presentation
The above plans provide a systematic and orderly approach to conducting a study The
plan includes both analytical and creative phases Each phase has its rules that are
designed to increase the effectiveness of the phase

INFLUENCE OF SELECTION OF TIME ON VALUE ENGINEERING(VE) APPLICATION
PHASE VALUE ENGINEEING EMPHASIS
CONCEPT FORMULATION PHASE
VE studies during this phase are directed at Furnishing inputs needed to ensure the most
economical decisions to achieve the functions sought
achieving low total cost of ownership (rather than just low acquisition cost)
TENTATIVE DESIGN PHASE
VE studies during this phase add value by analysing and developing alternatives for the following
Essential requirements Technical characteristics Design tasks
FINAL DESIGN PHASE VE studies during this phase are limited to
Eliminating unnecessarily restrictive detail and eliminating items not necessary
Redesign effort at this stage cannot be economically accomplished due to the implementation costs involved
CONSTRUCTION MANUFACTURING PHASE
VE studies during this phase result in
Extension of an items life Reduced repair costs Savings in energy and other operating costs Reduction in the number of supply items in stockVE can be performed both internally and by the contractorvendor
Value Methodology (also called Value Engineering Value Analysis or Value
Management) is a powerful problem- solving tool that can reduce costs while
maintaining or improving performance and quality requirements It is a function-oriented
systematic team approach to providing value in a product or service
The value methodology helps organizations compete more effectively in local national
and
international markets by
-Decreasing costs
-Increasing profits
-Improving quality
-Expanding market share
-Saving time
-Solving problems
-Using resources more effectively
VALUE ANALYSIS amp VALUE ENGINEERING
Value analysis is systematic creative and organized approach amp to identify unnecessary
costValue engineering is a technique of application to eliminate unnecessary cost
Generally value analysis is based for cost values Unless otherwise is specified
Value Analysis is an effective tool for cost reduction and the results accomplished are far
greater It improves the effectiveness of work that has been conventionally performed as
it questions and probes into the very purpose design method of manufacture etc of the
product with a view to pinpointing unnecessary costs obvious and hidden which can be
eliminated without adversely affecting quality efficiency safety and other customer
features
VALUE AND VALUE ANALYSIS
Let us consider at this stage what is meant by ldquoValuersquo lsquoValuersquo is itself is some what
difficult to define It means different things to different people
Value Analysis
VA is an step by step approach to identify the functions of a product process system or
service to establish a monetary value for that function and then provide the desired
function
at an overall minimum cost without affecting any of the existing parameters like Quality
Maintainability Productivity Safety and other Performance characteristics
Also it is often confused with the cost and price of a product or service One way of
defining the value of an item is
Worth to you
Value = ------------------
Price you pay
This means that if you feel that you have your moneyrsquos worth then you have received
100 per cent value Which indicates that lsquoValuersquo has a subjective aspect for what is good
value for one person need not necessarily be so far another In general if for any function
or a product or a service you feel you are paying too much or it costs you more than you
think it should there is scope for improving its lsquovaluersquo into it This leads us on to another
useful way of looking at lsquovaluersquo Value is the least cost that can accomplish reliably a
function or a service This implies that in achieving reduced cost the quality and
performance of the item are maintained It follows therefore that value analysis is a
technique which builds ldquoValuersquo into an item Value can also be defined as that
combination of quality efficiency price and service which ensures the ultimate economy
and satisfaction of the purchaser Value Analysis can be understood as a technique which
helps everyone to determine this combination It can be seen therefore that several
components make up lsquoValuersquo There is value arising from the function or end use of an
item and from its ability to perform a useful function reliable There is the subjective
aspect of value in terms of esteem or prestige value or artistic value for example the
extra chrome 63 and styling used to sell automobiles or the neck-tie or diamond ring you
may wear Again there is the cost value made up of the material and labour costs
overheads and any other costs incurred in producing the item However in the popular
mind this is closely associated with esteem value as there is a mistaken belief that
because something costs more it is worth more Finally there is the resale or exchange
value which may be taken as the ability to part with money for possessing a particular
product In addition we have place value with regard to the usefulness of a product at a
particular place
VARIOUS VALUES CONSIDERED BY VALUE ANALYSEE
1) Huge or functional Value-
It is due to the characteristic quality attributes property of the product by virtue of
which the product performs intended function most satisfactorily with minimum
maintenance
2) Aesthetic Value-
It is due to characteristic attributes property quality because of which product becomes
attractive elegant looking creates sales appeal color shade style texture etc
3) Exchange Value-
It is in terms of the amount of any other commodity that can be obtained in exchange of
the commodity under consideration It depends on time and place
4) Esteem Value-
It is due to special characteristics some manufacturers enjoy customer goodwill and
historical prestige
5) Cost Value-
It is the total of all the costs incurred to manufacture a product ie Unnecessary cost due
to
sect Bad product design
sect Inefficient manufacturing method
sect Inefficient manufacturing processes
sect Lack of Standardization
sect Choose of wrong machine and tools
sect Bad Layout
sect Bad working conditions
sect Accidents to the worker
sect Machine breakdown
sect Bad quality Raw material
sect Lack of training to the workers
sect Excessive variety of products
sect Frequent changes in product design
sect Improper material handling
sect Defective packaging of product
sect Waiting

APPLICATION OF VALUE ANALYSIS
Value analysis can be applied universally ie to everything ndash materials methods
processes services etc where it is intended to bring about economics One should
naturally start with items where the maximum annual saving can be achieved This
immediately suggests that items whose total annual consumption in Rupees is high
should receive top priorities in the application of Value Analysis In the same manner
scarce materials imported materials or those difficult to obtain should also receive the
attention of the value analyst Bearing this in mind Value Analysis can be systematically
applied to categories of items such as those listed below in order to bring about
substantial cost reduction
1 Capital goods ndash plant equipment machinery tools and appliances
2 Raw and semi-processed material including fuel
3 Sub-contracted parts components sub-assemblies etc
4 Purchased parts components sub-assemblies etc
5 Maintenance repairs and operational items
6 Finishing items such as paints oils varnishes etc
7 Packing materials and packaging
8 Printing and Stationery items
9 Miscellaneous items of regular consumptions
10 Power water supply compressed air steam and other utilities
(services) and
11 Materials handling and transportation costs
As mentioned earlier items where the saving can be substantial should obviously
be taken up first Also items which are imported or difficult to obtain and monopoly
items should receive high priority
However even if no economy can be effected immediately by Value Analysis on any
particular item then usefulness of the technique should not be forgotten altogether The
item should be taken up again for value analysis after six months or a year the period
being dictated by the findings of the investigation New ideas may come to your mind at
some other time Also it should be noted that the conditions in the market keep on
changing fast and new materials new suppliers and new processes come into existence
rapidly as a result of phenomenal technological progress taking place at present A
frequent and systematic review of the items already value analyzed with advantage may
result in further economies
ORGANISATION FOR VALUE ANALYSIS
Value analysis is a staff function like for instance Industrial Engineering and should be
organized as much It should be directly under a high-ranking officer from the Senior
Management of an undertaking This is necessary because Value Analysis concerns all
departments and the analyst must have access to them and to their records performance
costs etc Depending upon the size of the undertaking and its scale of operations there
can be a Central Value Analysis Cell to co-ordinate the work of individual analysts
attached to the design purchase production and engineering departments Where there is
only one Value Analyst he may be attached to the Industrial Engineering Department
or to the Purchase Department
Value Analysis is essentially a team effort What particular items to be taken up for value
analysis and what action is to be taken is usually decided by a small committee
comprising representatives from the Design Production Purchase and Accounts
Departments Any other departmental representative can be coopted if and when
necessary
It is the Purchase Manager (or Material Manager) who has to initiate action convene
meetings at regular intervals and see that substantial results are obtained A large share
of the initial phase of the Value Analysis work will be done by the Purchase Manager or
by other departments at his instance It is his responsibility to seek the maximum value
when a product requirement comes upto the point of purchase It is his duty to challenge
wasteful and avoidable costs inherent in the items he is asked to buy It is therefore
inevitable that a large part of whatever Value Analysis work is done is initiated by the
Purchase Manager
WHEN VALUE ANALYSIS
A product goes through 3 stages (1) Developmental (2) Growth and (3) Maturity before
being out of date Consider now the design efforts put on a product At developmental
stages the design effort is the maximum At the growth stage the effort is much less and is
mainly modifications and changes At maturity stage hardly any design attention is
needed The value of the product slowly increases in development and growth stages as
more features are added and desired changes and modifications are effected At maturity
stage the value increases to peak and then slowly starts reduction because of competition
change of customer tastes and other factors till the product falls out and becomes out of
date It is this stage where value analysis can still enhance the value by cost reduction
and lengthen the Maturity period of a product Thus when the design effort is diverted to
other products it is the time for value analysis to be undertaken The success of value
analysis for one product of course be made use of in the design of other products by
development wing

All factors come together including workers It is always done by a specific product
subcontractors engineers to make a team with total design (engineers )team
experience and knowledge
It may change the present stage of the product The changes are executed
at the initial stages only

It is worked out mostly with help of knowledge It requires specific
technical knowledge
and experience
VALUE ANALYSIS JOB PLAN
Several versions of the VA Job Plan can be found in different literature Some give file
others six and yet many other seven phases It is the systematic approach which is more
important to achieve the desired objectives The phases of VA Job Plan are as follows
SELECTION amp ORIENTATION
ANALYSIS
RECORDING IDEAS
SPECULATION
INVESTIGATION
RECOMMENDATION
IMPLEMENTATION
1) SELECTION amp - to select those problems areas ORIENTATION where a potential for
net higher Savings is expected - use the common paretorsquos ABC analysis - general scope
restrictions and aims of the study is defined
2) ANALYSIS - to examine the data at a coordinated syndicate meeting - to appoint a
secretary to record the minutes - to apply the Tests for Value - to propose further actions
3) RECORDING IDEAS - the secretary writes clearly the minutes of the analysis
meeting
and circulates them to syndicate members - it includes the agenda for the next meeting
4) SPECULATION - to hold additional syndicate 64 meetings in order to discuss the
ideas analysed and any new information obtained - to speculate upon practical measures
for reducing costs and increasing value
5) INVESTIGATION - to investigate suggestions for reducing costs and to make them
practical and acceptable - to obtain definite prices and costs in order to estimate savings
accurately
6) RECOMMENDATION - recommended practical savings to management for
implementing - to present the recommendations as a comprehensive report - to appoint a
member to act as an implementation consultant
7) IMPLEMENTATION - to decide on future plans for the company for which the
authority of the management is needed - to implement the recommendations acceptable to
the management
The value of a function can be increased by four methods
1 Decrease the cost while ensuring the same level of performance
2 Enhance the performance at the same cost
3 Decrease the cost and increase the performance
4 Increase both performance and cost ensuring that performance increases more than
the increment in the cost
ORGANISATION FOR VALUE ANALYSIS
Value analysis is a staff function like for instance Industrial Engineering and should be
organized as much It should be directly under a high-ranking officer from the Senior
Management of an undertaking This is necessary because Value Analysis concerns all
departments and the analyst must have access to them and to their records performance
costs etc Depending upon the size of the undertaking and its scale of operations there
can be a Central Value Analysis Cell to co-ordinate the work of individual analysts
attached to the design purchase production and engineering departments Where there is
only one Value Analyst he may be attached to the Industrial Engineering Department or
to the Purchase Department Value Analysis is essentially a team effort What particular
items to be taken up for value analysis and what action is to be taken is usually decided
by a small committee comprising representatives from the Design Production Purchase
and Accounts Departments Any other departmental representative can be coopted if and
when necessary It is the Purchase Manager (or Material Manager) who has to initiate
action convene meetings at regular intervals and see that substantial results are obtained
A large share of the initial phase of the Value Analysis work will be done by the
Purchase Manager or by other departments at his instance It is his responsibility to seek
the maximum value when a product requirement comes upto the point of purchase It is
his duty to challenge wasteful and avoidable costs inherent in the items he is asked to
buy It is therefore inevitable that a large part of whatever Value Analysis work is done
is initiated by the Purchase Manager
VALUE ENGINEERING
Value engineering is the term applied to value analysis done the design and prototype
stage of a product The potentials of saving are a more in case value analysis is done at
design stage Other advantages is that any changes at this stage are less costly than to
effect the same at a latter stage when the production is in full swing There are a few
limitations however on value engineering work At the design and proto-type stage the
time is rather short since a company wants to put a new product in the market before any
of its competitors can set in and value engineering will have a very short time to apply
their techniques Evaluation of the value at this stage becomes difficult in absence of any
customer reaction and opinion
WHEN VALUE ANALYSIS
A product goes through 3 stages (1) Developmental (2) Growth and (3) Maturity before
being out of date Consider now the design efforts put on a product At developmental
stages the design effort is the maximum At the growth stage the effort is much less and is
mainly modifications and changes At maturity stage hardly any design attention is
needed The value of the product slowly increases in development and growth stages as
more features are added and desired changes and modifications are effected At maturity
stage the value increases to peak and then slowly starts reduction because of competition
change of customer tastes and other factors till the product falls out and becomes out of
date It is this stage where value analysis can still enhance the value by cost reduction
and lengthen the Maturity period of a product Thus when the design effort is diverted to
other products it is the time for value analysis to be undertaken The success of value
analysis for one product of course be made use of in the design of other products by
development wing
CASE STUDY
ldquoCost Reduction of a product throughValue Analysis amp Value Engineeringrdquo
Introduction
The current business scenario is very demanding with a continuous demand from the
market forces to reduce the product price The pricing as demanded by the market forces
the businesses to reduce product development and manufacturing costs to remain
competitive Manufacturing costs of a product can be broadly categorized in the
following heads
bull Raw material
bull Labor
bull Process that is technology driven
Product engineers are constantly faced with the following challenges
bull Reduce production cost
bull Reduce the material cost
Value Analysis amp Value Engineering (VAVE) methods are very important and useful
in driving down the product cost which helps companies retain market share and sustain
their profitability
At QuEST we uncover those projects of our customer which have a good potential to
improve profits QuEST has a team of engineers who specialize in VAVE to achieve cost
reductions of products
A typical VAVE exercise could reduce the total cost of a product by 5-40 The typical
elements of a VAVE exercise are as follows
bull Information Understand the current state of the project and constraints requirements
bull Function Analysis Understand the project from a functional perspective what must
the project do rather than how the project is currently conceived The function describes
what something does and function analysis is the process where the team reviews the
projects functions to determine those that could be improved Function Analysis can be
enhanced through the use of a graphical mapping tool known as the Function Analysis
System Technique (FAST) FAST applies intuitive logic to test functions create a
common language for a team and test the validity of the functions in the project
bull Creative Generate a quantity of ideas related to other ways to perform the functions
bull Evaluation Reduce the quantity of ideas that have been identified to a short list of
ideas with the greatest potential to improve the project and meet the Value Engineering
study objective
bull Development Further analyze and develop the short list of ideas and develop those
with merit into value alternatives
bull Presentation Phase Implementation Present value alternatives to management team
and other project stakeholders or decision makers
5 Typical Flowchart
An example
The approach to a real life problem and the methodology followed by QuEST to reduce
the product cost is demonstrated through the following example
51 Background and Problem statement
One of the customers of QuEST is a leading manufacturer of industrial components for
control applications This unit is very popular in high end applications
The customer wanted to develop a unit that not only costs 25 less but whose
performance exceeds that of the existing product
52 Challenges
bull Redesign of parts considering minimum impact on existing tooling
bull Redesigned modules should enable field replacement
bull LogicSoftware compatibility with field units
bull Ease of assembly
bull Design must match existing housings and connectors
bull No modification of standardized parts in the product family
54 Value Engineering Study
QuEST team captured the detailed requirements of the project from the Voice of
Customer (VOC) during the kick off meeting It helped to identify areas where cost could
be reduced and which functions needed to be improved to provide competitive advantage
The requirements were listed and prioritized as primary and secondary These prioritized
ldquoNeeds and Wantsrdquo were ranked Quality Function Deployment (QFD) tool was used to
prioritize the ldquoHowrsquosrdquo that affected the ldquoNeeds and Wantsrdquo of the customer The
customer also actively participated in this exercise Vital few options were prioritized
from the trivial many Design requirement ranks were sorted in descending order and
those which addressed 70 of the requirements were selected Thus CTQs or
performance characteristics were identified and agreed upon with the customer The team
then carried out the lsquoABC analysisrsquo on the BOM Components with more than 80 of the
product cost were identified
CTQ (Critical to Quality)
Matches basic function and performance characteristics
One to one module replacement
Same Outer dimensions for the modules
LogicSoftware compatibility with field units
No modification in standardized parts in Product family
Design must match existing housings and connectors
Reduce the cost of direct material by 25 or more
Next the VAVE team laid down the Functions of each item of the product for Value
analysis
This enhanced the understanding of the product functionality This also helped to
understand the Form Fit amp Functions of each of the items amp sub-assemblies With this
study the VAVE team had divided the main project into many sub-projects with respect
to subassemblies to have diversified results for subassemblies and parts This function
diagram threw up many questions to the team which enabled them to come up with a
number of new ideas
bull How the Product is sized What design parameters were employed for this product
bull Focus on high cost components and challenge by asking ldquowhy do we need this part and
what value does it provide to our customerrdquo
bull How else we can designmake it
bull Understand design change impact on subassembly or overall product
bull System level appraisal is desirable to consider different methods or concepts for
delivering the same or better value
bull Component level assessment is lookedfor to consider alternate materials processes and
more efficient designs
bull One of the guiding principles of lean design is to ldquoeliminate or standardizerdquo Can a part
be combined with others and thereby be eliminated If not can it be made common with
other parts in the product
without compromising FFF (Form Fit amp Function) This typically provides quick savings
bull Identify and capture all cost reduction opportunities
The team applied the concept of Pugh Matrix for system amp component level Rankings
were discussed with team collated and analyzed for choosing the optimum concepts
Next FMEA was conducted on the selected concepts to further fine tune the results
Failure modes with high Risk Priority Number (RPN) were identified Failure modes
were prioritized and communicated to the designers to address these risks Alternate
solutions and improvement were discussed and finalized 3D solid modeling was done to
visualize the product It also helped to simulate the active and passive conditions of the
product Components were standardized to reduce the part count Simulation and testing
against the CTQs helped to optimize the product for performances Design calculations
were performed to verify the design for gears springs snaps in the plastic members etc
Also the DFMA was conducted on various aspects of the design amp CTQs A detailed
Differential Cost Analysis was conducted with the customer and their suppliers The
result showed significant cost reduction of each part of the product It was observed that
the costs were reduced mainly due to alternate materials usage the process and by
eliminationreplacement of a part by integrating with the adjacent one
Costs of direct material were compared for the original and new design A significant
38 of savings in direct material cost was realized by this project The team also
achieved a reduction of 34 in the part count This has resulted in many intangible
benefits like savings in procurement costs Inspection costs Inventory cost
transportation reduced variation reduced assembly costs amp Time etc
6 Conclusion
QuEST lsquoValue Engineering teamrsquo achieved 38 of savings in direct material cost and
reduced part count by 34 in this project Having a Paint brush does not make one a
painter While we strive to implement the different VAVE tools we realize that the years
of experience in product design amp development is very essential to achieve the desired
objective VAVE tools and techniques if applied properly with trained amp experienced
resources will provide an extremely powerful suite to improve productivity lower cost
improve quality and also shorten the time-to-market

CONCLUSION
Value analysis is a technique with immense possibilities and systematically employed it
can achieve great economies and increased efficiency Although good results have been
obtained in several individual cases in some industries only a large scale and systematic
application of this technique in all industries and in defence production can result in
substantial economies on a national scale
This valuable technique if systematically employed promises rich dividends and
among other things enables greater use of indigenous raw materials and equipment by
import substitution It is therefore of special significance to a developing country like
India which has adopted a programme of rapid industrialization in the face of paucity of
foreign exchange and other handicaps
No Company can take seriously Total Quality Management without operating a
formalized system of Value Analysis No business that wishes to become lean will ever
succeed if product designs remain unchanged because no amount of continuous
improvement in the manufacturing process can release the costs of a poor design or a
design that has not changed for many years
However poor product reviews or an informal process that is restricted to only to a
review of the design by the design department will yield only limited success in
eliminating lsquoavoidable costsrsquo These efforts will miss the many opportunities to make
manufacturing and assembly easier quicker less complex and less costly Thus margins
will not be improved significantly because only a small part of the total process has been
managed correctly As such this type of superficial activity will not generate increased
profit and the revenue stream that will be needed to finance new products and new
investments in technology A properly managed and effective VA process will easily
repay the time invested by managers over the life of the product and a truly effective
process will yield significant competitive advantage for companies that exploit it For
businesses that supply other organizations the ability to design and redesign products
opens the possibility of true meaningful profitable and long-term partnership with a
customer Each progressive step that secures a greater design responsibility for the
supplier will in parallel make the supplier increasingly more important to the
competitive advantage of the customer organization and will increase the benefits to both
companies In an environment where budgets are often reduced the market determines
the selling price of a product and consumers demand a greater variety of products VA is
one technique that companies cannot afford to ignore because for every day that the
technique is not employed is money that will leave the business forever Money that
cannot be recovered once the product has been sold
The benefits of a formalized and effective VA process are therefore many and include
some key sources of competitive advantage for any business including
bull Speed of getting an effective design into the market without problems and through
error-free manufacturing and assembly processes
bull Reliability and durability of the product in the market which enhances the reputation
of the product and the company
bull Low overall cost which enhances product margin and also releases finances within the
business as well as allowing the ability to engage in price competition
bull Enhanced quality and compliance with minimal costs of warranty that allows a
company to differentiate its products based this perceived quality (of use and esteem)
bull Differentiation by creating product designs as platforms which facilitate lsquolast
minutersquo or late configuration of the product to meet customer orders regional preferences
or any other geographical constraint (such as product laws of a certain region)
bull Finally the VA process satisfies the primary goal of any business ndash to make a profit
and survive
As a process VA is very robust and offers tangible financial and people-based benefits
The process eliminates unnecessary weight it removes unnecessary costs and importantly
it allows people to understand products processes and continuous improvement Very
few modern management techniques allow this form of participation and involvement
and even fewer have such a profound impact on the bottom line of the businessrsquos trading
accounts For companies that do not employ this technique there is one very frightening
thought that for every product that the company makes one or two may be bought by
competitors and subjected to value analysis Therefore these competitors can easily
recover the ground lost to any lsquobreakthroughrsquo new product with half the effort and half
the expense of starting from the beginning These competitors can also take the new
product and lsquostreamlinersquo it to offer maximum value at minimum cost thereby creating a
new product without any real expense This is perhaps the most frightening though of all

Value Methodology (also called Value Engineering Value Analysis or Value
Management) is a powerful problem- solving tool that can reduce costs while
maintaining or improving performance and quality requirements It is a function-oriented
systematic team approach to providing value in a product or service
The value methodology helps organizations compete more effectively in local national
and
international markets by
-Decreasing costs
-Increasing profits
-Improving quality
-Expanding market share
-Saving time
-Solving problems
-Using resources more effectively
VALUE ANALYSIS amp VALUE ENGINEERING
Value analysis is systematic creative and organized approach amp to identify unnecessary
costValue engineering is a technique of application to eliminate unnecessary cost
Generally value analysis is based for cost values Unless otherwise is specified
Value Analysis is an effective tool for cost reduction and the results accomplished are far
greater It improves the effectiveness of work that has been conventionally performed as
it questions and probes into the very purpose design method of manufacture etc of the
product with a view to pinpointing unnecessary costs obvious and hidden which can be
eliminated without adversely affecting quality efficiency safety and other customer
features
VALUE AND VALUE ANALYSIS
Let us consider at this stage what is meant by ldquoValuersquo lsquoValuersquo is itself is some what
difficult to define It means different things to different people
Value Analysis
VA is an step by step approach to identify the functions of a product process system or
service to establish a monetary value for that function and then provide the desired
function
at an overall minimum cost without affecting any of the existing parameters like Quality
Maintainability Productivity Safety and other Performance characteristics
Also it is often confused with the cost and price of a product or service One way of
defining the value of an item is
Worth to you
Value = ------------------
Price you pay
This means that if you feel that you have your moneyrsquos worth then you have received
100 per cent value Which indicates that lsquoValuersquo has a subjective aspect for what is good
value for one person need not necessarily be so far another In general if for any function
or a product or a service you feel you are paying too much or it costs you more than you
think it should there is scope for improving its lsquovaluersquo into it This leads us on to another
useful way of looking at lsquovaluersquo Value is the least cost that can accomplish reliably a
function or a service This implies that in achieving reduced cost the quality and
performance of the item are maintained It follows therefore that value analysis is a
technique which builds ldquoValuersquo into an item Value can also be defined as that
combination of quality efficiency price and service which ensures the ultimate economy
and satisfaction of the purchaser Value Analysis can be understood as a technique which
helps everyone to determine this combination It can be seen therefore that several
components make up lsquoValuersquo There is value arising from the function or end use of an
item and from its ability to perform a useful function reliable There is the subjective
aspect of value in terms of esteem or prestige value or artistic value for example the
extra chrome 63 and styling used to sell automobiles or the neck-tie or diamond ring you
may wear Again there is the cost value made up of the material and labour costs
overheads and any other costs incurred in producing the item However in the popular
mind this is closely associated with esteem value as there is a mistaken belief that
because something costs more it is worth more Finally there is the resale or exchange
value which may be taken as the ability to part with money for possessing a particular
product In addition we have place value with regard to the usefulness of a product at a
particular place
VARIOUS VALUES CONSIDERED BY VALUE ANALYSEE
1) Huge or functional Value-
It is due to the characteristic quality attributes property of the product by virtue of
which the product performs intended function most satisfactorily with minimum
maintenance
2) Aesthetic Value-
It is due to characteristic attributes property quality because of which product becomes
attractive elegant looking creates sales appeal color shade style texture etc
3) Exchange Value-
It is in terms of the amount of any other commodity that can be obtained in exchange of
the commodity under consideration It depends on time and place
4) Esteem Value-
It is due to special characteristics some manufacturers enjoy customer goodwill and
historical prestige
5) Cost Value-
It is the total of all the costs incurred to manufacture a product ie Unnecessary cost due
to
sect Bad product design
sect Inefficient manufacturing method
sect Inefficient manufacturing processes
sect Lack of Standardization
sect Choose of wrong machine and tools
sect Bad Layout
sect Bad working conditions
sect Accidents to the worker
sect Machine breakdown
sect Bad quality Raw material
sect Lack of training to the workers
sect Excessive variety of products
sect Frequent changes in product design
sect Improper material handling
sect Defective packaging of product
sect Waiting
sect Searching
sect Bad house keeping etc

APPLICATION OF VALUE ANALYSIS
Value analysis can be applied universally ie to everything ndash materials methods
processes services etc where it is intended to bring about economics One should
naturally start with items where the maximum annual saving can be achieved This
immediately suggests that items whose total annual consumption in Rupees is high
should receive top priorities in the application of Value Analysis In the same manner
scarce materials imported materials or those difficult to obtain should also receive the
attention of the value analyst Bearing this in mind Value Analysis can be systematically
applied to categories of items such as those listed below in order to bring about
substantial cost reduction
1 Capital goods ndash plant equipment machinery tools and appliances
2 Raw and semi-processed material including fuel
3 Sub-contracted parts components sub-assemblies etc
4 Purchased parts components sub-assemblies etc
5 Maintenance repairs and operational items
6 Finishing items such as paints oils varnishes etc
7 Packing materials and packaging
8 Printing and Stationery items
9 Miscellaneous items of regular consumptions
10 Power water supply compressed air steam and other utilities
(services) and
11 Materials handling and transportation costs
As mentioned earlier items where the saving can be substantial should obviously
be taken up first Also items which are imported or difficult to obtain and monopoly
items should receive high priority
However even if no economy can be effected immediately by Value Analysis on any
particular item then usefulness of the technique should not be forgotten altogether The
item should be taken up again for value analysis after six months or a year the period
being dictated by the findings of the investigation New ideas may come to your mind at
some other time Also it should be noted that the conditions in the market keep on
changing fast and new materials new suppliers and new processes come into existence
rapidly as a result of phenomenal technological progress taking place at present A
frequent and systematic review of the items already value analyzed with advantage may
result in further economies
ORGANISATION FOR VALUE ANALYSIS
Value analysis is a staff function like for instance Industrial Engineering and should be
organized as much It should be directly under a high-ranking officer from the Senior
Management of an undertaking This is necessary because Value Analysis concerns all
departments and the analyst must have access to them and to their records performance
costs etc Depending upon the size of the undertaking and its scale of operations there
can be a Central Value Analysis Cell to co-ordinate the work of individual analysts
attached to the design purchase production and engineering departments Where there is
only one Value Analyst he may be attached to the Industrial Engineering Department
or to the Purchase Department
Value Analysis is essentially a team effort What particular items to be taken up for value
analysis and what action is to be taken is usually decided by a small committee
comprising representatives from the Design Production Purchase and Accounts
Departments Any other departmental representative can be coopted if and when
necessary
It is the Purchase Manager (or Material Manager) who has to initiate action convene
meetings at regular intervals and see that substantial results are obtained A large share
of the initial phase of the Value Analysis work will be done by the Purchase Manager or
by other departments at his instance It is his responsibility to seek the maximum value
when a product requirement comes upto the point of purchase It is his duty to challenge
wasteful and avoidable costs inherent in the items he is asked to buy It is therefore
inevitable that a large part of whatever Value Analysis work is done is initiated by the
Purchase Manager
WHEN VALUE ANALYSIS

important to achieve the desired objectives The phases of VA Job Plan are as follows

the management
The value of a function can be increased by four methods
1 Decrease the cost while ensuring the same level of performance
2 Enhance the performance at the same cost
3 Decrease the cost and increase the performance
4 Increase both performance and cost ensuring that performance increases more than
the increment in the cost

bull Information Understand the current state of the project and constraints requirements
bull Function Analysis Understand the project from a functional perspective what must
the project do rather than how the project is currently conceived The function describes
what something does and function analysis is the process where the team reviews the
projects functions to determine those that could be improved Function Analysis can be
enhanced through the use of a graphical mapping tool known as the Function Analysis
System Technique (FAST) FAST applies intuitive logic to test functions create a
common language for a team and test the validity of the functions in the project
bull Creative Generate a quantity of ideas related to other ways to perform the functions
bull Evaluation Reduce the quantity of ideas that have been identified to a short list of
ideas with the greatest potential to improve the project and meet the Value Engineering
study objective
bull Development Further analyze and develop the short list of ideas and develop those
with merit into value alternatives
bull Presentation Phase Implementation Present value alternatives to management team
and other project stakeholders or decision makers
5 Typical Flowchart
An example
The approach to a real life problem and the methodology followed by QuEST to reduce
the product cost is demonstrated through the following example
51 Background and Problem statement
One of the customers of QuEST is a leading manufacturer of industrial components for
control applications This unit is very popular in high end applications
The customer wanted to develop a unit that not only costs 25 less but whose
performance exceeds that of the existing product
52 Challenges
bull Redesign of parts considering minimum impact on existing tooling
bull Redesigned modules should enable field replacement
bull LogicSoftware compatibility with field units
bull Ease of assembly
bull Design must match existing housings and connectors
bull No modification of standardized parts in the product family
54 Value Engineering Study
QuEST team captured the detailed requirements of the project from the Voice of
Customer (VOC) during the kick off meeting It helped to identify areas where cost could
be reduced and which functions needed to be improved to provide competitive advantage
The requirements were listed and prioritized as primary and secondary These prioritized
ldquoNeeds and Wantsrdquo were ranked Quality Function Deployment (QFD) tool was used to
prioritize the ldquoHowrsquosrdquo that affected the ldquoNeeds and Wantsrdquo of the customer The
customer also actively participated in this exercise Vital few options were prioritized
from the trivial many Design requirement ranks were sorted in descending order and
those which addressed 70 of the requirements were selected Thus CTQs or
performance characteristics were identified and agreed upon with the customer The team
then carried out the lsquoABC analysisrsquo on the BOM Components with more than 80 of the
product cost were identified
CTQ (Critical to Quality)
Matches basic function and performance characteristics
One to one module replacement
Same Outer dimensions for the modules
LogicSoftware compatibility with field units
No modification in standardized parts in Product family
Design must match existing housings and connectors
Reduce the cost of direct material by 25 or more
Next the VAVE team laid down the Functions of each item of the product for Value
analysis
This enhanced the understanding of the product functionality This also helped to
understand the Form Fit amp Functions of each of the items amp sub-assemblies With this
study the VAVE team had divided the main project into many sub-projects with respect
to subassemblies to have diversified results for subassemblies and parts This function
diagram threw up many questions to the team which enabled them to come up with a
number of new ideas
bull How the Product is sized What design parameters were employed for this product
bull Focus on high cost components and challenge by asking ldquowhy do we need this part and
what value does it provide to our customerrdquo
bull How else we can designmake it
bull Understand design change impact on subassembly or overall product
bull System level appraisal is desirable to consider different methods or concepts for
delivering the same or better value
bull Component level assessment is lookedfor to consider alternate materials processes and
more efficient designs
bull One of the guiding principles of lean design is to ldquoeliminate or standardizerdquo Can a part
be combined with others and thereby be eliminated If not can it be made common with
other parts in the product
without compromising FFF (Form Fit amp Function) This typically provides quick savings
bull Identify and capture all cost reduction opportunities
The team applied the concept of Pugh Matrix for system amp component level Rankings
were discussed with team collated and analyzed for choosing the optimum concepts
Next FMEA was conducted on the selected concepts to further fine tune the results
Failure modes with high Risk Priority Number (RPN) were identified Failure modes
were prioritized and communicated to the designers to address these risks Alternate
solutions and improvement were discussed and finalized 3D solid modeling was done to
visualize the product It also helped to simulate the active and passive conditions of the
product Components were standardized to reduce the part count Simulation and testing
against the CTQs helped to optimize the product for performances Design calculations
were performed to verify the design for gears springs snaps in the plastic members etc
Also the DFMA was conducted on various aspects of the design amp CTQs A detailed
Differential Cost Analysis was conducted with the customer and their suppliers The
result showed significant cost reduction of each part of the product It was observed that
the costs were reduced mainly due to alternate materials usage the process and by
eliminationreplacement of a part by integrating with the adjacent one
Costs of direct material were compared for the original and new design A significant
38 of savings in direct material cost was realized by this project The team also
achieved a reduction of 34 in the part count This has resulted in many intangible
benefits like savings in procurement costs Inspection costs Inventory cost
transportation reduced variation reduced assembly costs amp Time etc
6 Conclusion
QuEST lsquoValue Engineering teamrsquo achieved 38 of savings in direct material cost and
reduced part count by 34 in this project Having a Paint brush does not make one a
painter While we strive to implement the different VAVE tools we realize that the years
of experience in product design amp development is very essential to achieve the desired
objective VAVE tools and techniques if applied properly with trained amp experienced
resources will provide an extremely powerful suite to improve productivity lower cost
improve quality and also shorten the time-to-market

CONCLUSION
Value analysis is a technique with immense possibilities and systematically employed it
can achieve great economies and increased efficiency Although good results have been
obtained in several individual cases in some industries only a large scale and systematic
application of this technique in all industries and in defence production can result in
substantial economies on a national scale
This valuable technique if systematically employed promises rich dividends and
among other things enables greater use of indigenous raw materials and equipment by
import substitution It is therefore of special significance to a developing country like
India which has adopted a programme of rapid industrialization in the face of paucity of
foreign exchange and other handicaps
No Company can take seriously Total Quality Management without operating a
formalized system of Value Analysis No business that wishes to become lean will ever
succeed if product designs remain unchanged because no amount of continuous
improvement in the manufacturing process can release the costs of a poor design or a
design that has not changed for many years
However poor product reviews or an informal process that is restricted to only to a
review of the design by the design department will yield only limited success in
eliminating lsquoavoidable costsrsquo These efforts will miss the many opportunities to make
manufacturing and assembly easier quicker less complex and less costly Thus margins
will not be improved significantly because only a small part of the total process has been
managed correctly As such this type of superficial activity will not generate increased
profit and the revenue stream that will be needed to finance new products and new
investments in technology A properly managed and effective VA process will easily
repay the time invested by managers over the life of the product and a truly effective
process will yield significant competitive advantage for companies that exploit it For
businesses that supply other organizations the ability to design and redesign products
opens the possibility of true meaningful profitable and long-term partnership with a
customer Each progressive step that secures a greater design responsibility for the
supplier will in parallel make the supplier increasingly more important to the
competitive advantage of the customer organization and will increase the benefits to both
companies In an environment where budgets are often reduced the market determines
the selling price of a product and consumers demand a greater variety of products VA is
one technique that companies cannot afford to ignore because for every day that the
technique is not employed is money that will leave the business forever Money that
cannot be recovered once the product has been sold
The benefits of a formalized and effective VA process are therefore many and include
some key sources of competitive advantage for any business including
bull Speed of getting an effective design into the market without problems and through
error-free manufacturing and assembly processes
bull Reliability and durability of the product in the market which enhances the reputation
of the product and the company
bull Low overall cost which enhances product margin and also releases finances within the
business as well as allowing the ability to engage in price competition
bull Enhanced quality and compliance with minimal costs of warranty that allows a
company to differentiate its products based this perceived quality (of use and esteem)
bull Differentiation by creating product designs as platforms which facilitate lsquolast
minutersquo or late configuration of the product to meet customer orders regional preferences
or any other geographical constraint (such as product laws of a certain region)
bull Finally the VA process satisfies the primary goal of any business ndash to make a profit
and survive
As a process VA is very robust and offers tangible financial and people-based benefits
The process eliminates unnecessary weight it removes unnecessary costs and importantly
it allows people to understand products processes and continuous improvement Very
few modern management techniques allow this form of participation and involvement
and even fewer have such a profound impact on the bottom line of the businessrsquos trading
accounts For companies that do not employ this technique there is one very frightening
thought that for every product that the company makes one or two may be bought by
competitors and subjected to value analysis Therefore these competitors can easily
recover the ground lost to any lsquobreakthroughrsquo new product with half the effort and half
the expense of starting from the beginning These competitors can also take the new
product and lsquostreamlinersquo it to offer maximum value at minimum cost thereby creating a
new product without any real expense This is perhaps the most frightening though of all

Value Methodology (also called Value Engineering Value Analysis or Value
Management) is a powerful problem- solving tool that can reduce costs while
maintaining or improving performance and quality requirements It is a function-oriented
systematic team approach to providing value in a product or service
The value methodology helps organizations compete more effectively in local national
and
international markets by
-Decreasing costs
-Increasing profits
-Improving quality
-Expanding market share
-Saving time
-Solving problems
-Using resources more effectively
VALUE ANALYSIS amp VALUE ENGINEERING
Value analysis is systematic creative and organized approach amp to identify unnecessary
costValue engineering is a technique of application to eliminate unnecessary cost
Generally value analysis is based for cost values Unless otherwise is specified
Value Analysis is an effective tool for cost reduction and the results accomplished are far
greater It improves the effectiveness of work that has been conventionally performed as
it questions and probes into the very purpose design method of manufacture etc of the
product with a view to pinpointing unnecessary costs obvious and hidden which can be
eliminated without adversely affecting quality efficiency safety and other customer
features
VALUE AND VALUE ANALYSIS
Let us consider at this stage what is meant by ldquoValuersquo lsquoValuersquo is itself is some what
difficult to define It means different things to different people
Value Analysis
VA is an step by step approach to identify the functions of a product process system or
service to establish a monetary value for that function and then provide the desired
function
at an overall minimum cost without affecting any of the existing parameters like Quality
Maintainability Productivity Safety and other Performance characteristics
Also it is often confused with the cost and price of a product or service One way of
defining the value of an item is
Worth to you
Value = ------------------
Price you pay
This means that if you feel that you have your moneyrsquos worth then you have received
100 per cent value Which indicates that lsquoValuersquo has a subjective aspect for what is good
value for one person need not necessarily be so far another In general if for any function
or a product or a service you feel you are paying too much or it costs you more than you
think it should there is scope for improving its lsquovaluersquo into it This leads us on to another
useful way of looking at lsquovaluersquo Value is the least cost that can accomplish reliably a
function or a service This implies that in achieving reduced cost the quality and
performance of the item are maintained It follows therefore that value analysis is a
technique which builds ldquoValuersquo into an item Value can also be defined as that
combination of quality efficiency price and service which ensures the ultimate economy
and satisfaction of the purchaser Value Analysis can be understood as a technique which
helps everyone to determine this combination It can be seen therefore that several
components make up lsquoValuersquo There is value arising from the function or end use of an
item and from its ability to perform a useful function reliable There is the subjective
aspect of value in terms of esteem or prestige value or artistic value for example the
extra chrome 63 and styling used to sell automobiles or the neck-tie or diamond ring you
may wear Again there is the cost value made up of the material and labour costs
overheads and any other costs incurred in producing the item However in the popular
mind this is closely associated with esteem value as there is a mistaken belief that
because something costs more it is worth more Finally there is the resale or exchange
value which may be taken as the ability to part with money for possessing a particular
product In addition we have place value with regard to the usefulness of a product at a
particular place
VARIOUS VALUES CONSIDERED BY VALUE ANALYSEE
1) Huge or functional Value-
It is due to the characteristic quality attributes property of the product by virtue of
which the product performs intended function most satisfactorily with minimum
maintenance
2) Aesthetic Value-
It is due to characteristic attributes property quality because of which product becomes
attractive elegant looking creates sales appeal color shade style texture etc
3) Exchange Value-
It is in terms of the amount of any other commodity that can be obtained in exchange of
the commodity under consideration It depends on time and place
4) Esteem Value-
It is due to special characteristics some manufacturers enjoy customer goodwill and
historical prestige
5) Cost Value-
It is the total of all the costs incurred to manufacture a product ie Unnecessary cost due
to
sect Bad product design
sect Inefficient manufacturing method
sect Inefficient manufacturing processes
sect Lack of Standardization
sect Choose of wrong machine and tools
sect Bad Layout
sect Bad working conditions
sect Accidents to the worker
sect Machine breakdown
sect Bad quality Raw material
sect Lack of training to the workers
sect Excessive variety of products
sect Frequent changes in product design
sect Improper material handling
sect Defective packaging of product
sect Waiting
sect Searching
sect Bad house keeping etc

APPLICATION OF VALUE ANALYSIS
Value analysis can be applied universally ie to everything ndash materials methods
processes services etc where it is intended to bring about economics One should
naturally start with items where the maximum annual saving can be achieved This
immediately suggests that items whose total annual consumption in Rupees is high
should receive top priorities in the application of Value Analysis In the same manner
scarce materials imported materials or those difficult to obtain should also receive the
attention of the value analyst Bearing this in mind Value Analysis can be systematically
applied to categories of items such as those listed below in order to bring about
substantial cost reduction
1 Capital goods ndash plant equipment machinery tools and appliances
2 Raw and semi-processed material including fuel
3 Sub-contracted parts components sub-assemblies etc
4 Purchased parts components sub-assemblies etc
5 Maintenance repairs and operational items
6 Finishing items such as paints oils varnishes etc
7 Packing materials and packaging
8 Printing and Stationery items
9 Miscellaneous items of regular consumptions
10 Power water supply compressed air steam and other utilities
(services) and
11 Materials handling and transportation costs
As mentioned earlier items where the saving can be substantial should obviously
be taken up first Also items which are imported or difficult to obtain and monopoly
items should receive high priority
However even if no economy can be effected immediately by Value Analysis on any
particular item then usefulness of the technique should not be forgotten altogether The
item should be taken up again for value analysis after six months or a year the period
being dictated by the findings of the investigation New ideas may come to your mind at
some other time Also it should be noted that the conditions in the market keep on
changing fast and new materials new suppliers and new processes come into existence
rapidly as a result of phenomenal technological progress taking place at present A
frequent and systematic review of the items already value analyzed with advantage may
result in further economies
ORGANISATION FOR VALUE ANALYSIS
Value analysis is a staff function like for instance Industrial Engineering and should be
organized as much It should be directly under a high-ranking officer from the Senior
Management of an undertaking This is necessary because Value Analysis concerns all
departments and the analyst must have access to them and to their records performance
costs etc Depending upon the size of the undertaking and its scale of operations there
can be a Central Value Analysis Cell to co-ordinate the work of individual analysts
attached to the design purchase production and engineering departments Where there is
only one Value Analyst he may be attached to the Industrial Engineering Department
or to the Purchase Department
Value Analysis is essentially a team effort What particular items to be taken up for value
analysis and what action is to be taken is usually decided by a small committee
comprising representatives from the Design Production Purchase and Accounts
Departments Any other departmental representative can be coopted if and when
necessary
It is the Purchase Manager (or Material Manager) who has to initiate action convene
meetings at regular intervals and see that substantial results are obtained A large share
of the initial phase of the Value Analysis work will be done by the Purchase Manager or
by other departments at his instance It is his responsibility to seek the maximum value
when a product requirement comes upto the point of purchase It is his duty to challenge
wasteful and avoidable costs inherent in the items he is asked to buy It is therefore
inevitable that a large part of whatever Value Analysis work is done is initiated by the
Purchase Manager
WHEN VALUE ANALYSIS
A product goes through 3 stages (1) Developmental (2) Growth and (3) Maturity before
being out of date Consider now the design efforts put on a product At developmental
stages the design effort is the maximum At the growth stage the effort is much less and is
mainly modifications and changes At maturity stage hardly any design attention is
needed The value of the product slowly increases in development and growth stages as
more features are added and desired changes and modifications are effected At maturity
stage the value increases to peak and then slowly starts reduction because of competition
change of customer tastes and other factors till the product falls out and becomes out of
date It is this stage where value analysis can still enhance the value by cost reduction
and lengthen the Maturity period of a product Thus when the design effort is diverted to
other products it is the time for value analysis to be undertaken The success of value
analysis for one product of course be made use of in the design of other products by
development wing

VALUE ANALYSIS JOB PLAN
Several versions of the VA Job Plan can be found in different literature Some give file
others six and yet many other seven phases It is the systematic approach which is more
important to achieve the desired objectives The phases of VA Job Plan are as follows
SELECTION amp ORIENTATION
ANALYSIS
RECORDING IDEAS
SPECULATION
INVESTIGATION
RECOMMENDATION
IMPLEMENTATION
1) SELECTION amp - to select those problems areas ORIENTATION where a potential for
net higher Savings is expected - use the common paretorsquos ABC analysis - general scope
restrictions and aims of the study is defined
2) ANALYSIS - to examine the data at a coordinated syndicate meeting - to appoint a
secretary to record the minutes - to apply the Tests for Value - to propose further actions
3) RECORDING IDEAS - the secretary writes clearly the minutes of the analysis
meeting
and circulates them to syndicate members - it includes the agenda for the next meeting
4) SPECULATION - to hold additional syndicate 64 meetings in order to discuss the
ideas analysed and any new information obtained - to speculate upon practical measures
for reducing costs and increasing value
5) INVESTIGATION - to investigate suggestions for reducing costs and to make them
practical and acceptable - to obtain definite prices and costs in order to estimate savings
accurately
6) RECOMMENDATION - recommended practical savings to management for
implementing - to present the recommendations as a comprehensive report - to appoint a
member to act as an implementation consultant
7) IMPLEMENTATION - to decide on future plans for the company for which the
authority of the management is needed - to implement the recommendations acceptable to
the management
The value of a function can be increased by four methods
1 Decrease the cost while ensuring the same level of performance
2 Enhance the performance at the same cost
3 Decrease the cost and increase the performance
4 Increase both performance and cost ensuring that performance increases more than
the increment in the cost

VALUE ENGINEERING
Value engineering is the term applied to value analysis done the design and prototype
stage of a product The potentials of saving are a more in case value analysis is done at
design stage Other advantages is that any changes at this stage are less costly than to
effect the same at a latter stage when the production is in full swing There are a few
limitations however on value engineering work At the design and proto-type stage the
time is rather short since a company wants to put a new product in the market before any
of its competitors can set in and value engineering will have a very short time to apply
their techniques Evaluation of the value at this stage becomes difficult in absence of any
customer reaction and opinion
WHEN VALUE ANALYSIS
A product goes through 3 stages (1) Developmental (2) Growth and (3) Maturity before
being out of date Consider now the design efforts put on a product At developmental
stages the design effort is the maximum At the growth stage the effort is much less and is

CASE STUDY
ldquoCost Reduction of a product throughValue Analysis amp Value Engineeringrdquo
Introduction
The current business scenario is very demanding with a continuous demand from the
market forces to reduce the product price The pricing as demanded by the market forces
the businesses to reduce product development and manufacturing costs to remain
competitive Manufacturing costs of a product can be broadly categorized in the
following heads
bull Raw material
bull Labor
bull Process that is technology driven
Product engineers are constantly faced with the following challenges
bull Reduce production cost
bull Reduce the material cost
Value Analysis amp Value Engineering (VAVE) methods are very important and useful
in driving down the product cost which helps companies retain market share and sustain
their profitability
At QuEST we uncover those projects of our customer which have a good potential to
improve profits QuEST has a team of engineers who specialize in VAVE to achieve cost
reductions of products
A typical VAVE exercise could reduce the total cost of a product by 5-40 The typical
elements of a VAVE exercise are as follows
bull Information Understand the current state of the project and constraints requirements
bull Function Analysis Understand the project from a functional perspective what must
the project do rather than how the project is currently conceived The function describes
what something does and function analysis is the process where the team reviews the
projects functions to determine those that could be improved Function Analysis can be
enhanced through the use of a graphical mapping tool known as the Function Analysis
System Technique (FAST) FAST applies intuitive logic to test functions create a
common language for a team and test the validity of the functions in the project
bull Creative Generate a quantity of ideas related to other ways to perform the functions
bull Evaluation Reduce the quantity of ideas that have been identified to a short list of
ideas with the greatest potential to improve the project and meet the Value Engineering
study objective
bull Development Further analyze and develop the short list of ideas and develop those
with merit into value alternatives
bull Presentation Phase Implementation Present value alternatives to management team
and other project stakeholders or decision makers

import substitution It is therefore of special significance to a developing country like
India which has adopted a programme of rapid industrialization in the face of paucity of
foreign exchange and other handicaps
No Company can take seriously Total Quality Management without operating a
formalized system of Value Analysis No business that wishes to become lean will ever
succeed if product designs remain unchanged because no amount of continuous
improvement in the manufacturing process can release the costs of a poor design or a
design that has not changed for many years
However poor product reviews or an informal process that is restricted to only to a
review of the design by the design department will yield only limited success in
eliminating lsquoavoidable costsrsquo These efforts will miss the many opportunities to make
manufacturing and assembly easier quicker less complex and less costly Thus margins
will not be improved significantly because only a small part of the total process has been
managed correctly As such this type of superficial activity will not generate increased
profit and the revenue stream that will be needed to finance new products and new
investments in technology A properly managed and effective VA process will easily
repay the time invested by managers over the life of the product and a truly effective
process will yield significant competitive advantage for companies that exploit it For
businesses that supply other organizations the ability to design and redesign products
opens the possibility of true meaningful profitable and long-term partnership with a
customer Each progressive step that secures a greater design responsibility for the
supplier will in parallel make the supplier increasingly more important to the
competitive advantage of the customer organization and will increase the benefits to both
companies In an environment where budgets are often reduced the market determines
the selling price of a product and consumers demand a greater variety of products VA is
one technique that companies cannot afford to ignore because for every day that the
technique is not employed is money that will leave the business forever Money that
cannot be recovered once the product has been sold
The benefits of a formalized and effective VA process are therefore many and include
some key sources of competitive advantage for any business including
bull Speed of getting an effective design into the market without problems and through
error-free manufacturing and assembly processes
bull Reliability and durability of the product in the market which enhances the reputation
of the product and the company
bull Low overall cost which enhances product margin and also releases finances within the
business as well as allowing the ability to engage in price competition
bull Enhanced quality and compliance with minimal costs of warranty that allows a
company to differentiate its products based this perceived quality (of use and esteem)
bull Differentiation by creating product designs as platforms which facilitate lsquolast
minutersquo or late configuration of the product to meet customer orders regional preferences
or any other geographical constraint (such as product laws of a certain region)
bull Finally the VA process satisfies the primary goal of any business ndash to make a profit
and survive
As a process VA is very robust and offers tangible financial and people-based benefits
The process eliminates unnecessary weight it removes unnecessary costs and importantly
it allows people to understand products processes and continuous improvement Very
few modern management techniques allow this form of participation and involvement
and even fewer have such a profound impact on the bottom line of the businessrsquos trading
accounts For companies that do not employ this technique there is one very frightening
thought that for every product that the company makes one or two may be bought by
competitors and subjected to value analysis Therefore these competitors can easily
recover the ground lost to any lsquobreakthroughrsquo new product with half the effort and half
the expense of starting from the beginning These competitors can also take the new
product and lsquostreamlinersquo it to offer maximum value at minimum cost thereby creating a
new product without any real expense This is perhaps the most frightening though of all

Value Methodology (also called Value Engineering Value Analysis or Value
Management) is a powerful problem- solving tool that can reduce costs while
maintaining or improving performance and quality requirements It is a function-oriented
systematic team approach to providing value in a product or service
The value methodology helps organizations compete more effectively in local national
and
international markets by
-Decreasing costs
-Increasing profits
-Improving quality
-Expanding market share
-Saving time
-Solving problems
-Using resources more effectively
VALUE ANALYSIS amp VALUE ENGINEERING
Value analysis is systematic creative and organized approach amp to identify unnecessary
costValue engineering is a technique of application to eliminate unnecessary cost
Generally value analysis is based for cost values Unless otherwise is specified
Value Analysis is an effective tool for cost reduction and the results accomplished are far
greater It improves the effectiveness of work that has been conventionally performed as
it questions and probes into the very purpose design method of manufacture etc of the
product with a view to pinpointing unnecessary costs obvious and hidden which can be
eliminated without adversely affecting quality efficiency safety and other customer
features
VALUE AND VALUE ANALYSIS
Let us consider at this stage what is meant by ldquoValuersquo lsquoValuersquo is itself is some what
difficult to define It means different things to different people
Value Analysis
VA is an step by step approach to identify the functions of a product process system or
service to establish a monetary value for that function and then provide the desired
function
at an overall minimum cost without affecting any of the existing parameters like Quality
Maintainability Productivity Safety and other Performance characteristics
Also it is often confused with the cost and price of a product or service One way of
defining the value of an item is
Worth to you
Value = ------------------
Price you pay
This means that if you feel that you have your moneyrsquos worth then you have received
100 per cent value Which indicates that lsquoValuersquo has a subjective aspect for what is good
value for one person need not necessarily be so far another In general if for any function
or a product or a service you feel you are paying too much or it costs you more than you
think it should there is scope for improving its lsquovaluersquo into it This leads us on to another
useful way of looking at lsquovaluersquo Value is the least cost that can accomplish reliably a
function or a service This implies that in achieving reduced cost the quality and
performance of the item are maintained It follows therefore that value analysis is a
technique which builds ldquoValuersquo into an item Value can also be defined as that
combination of quality efficiency price and service which ensures the ultimate economy
and satisfaction of the purchaser Value Analysis can be understood as a technique which
helps everyone to determine this combination It can be seen therefore that several
components make up lsquoValuersquo There is value arising from the function or end use of an
item and from its ability to perform a useful function reliable There is the subjective
aspect of value in terms of esteem or prestige value or artistic value for example the
extra chrome 63 and styling used to sell automobiles or the neck-tie or diamond ring you
may wear Again there is the cost value made up of the material and labour costs
overheads and any other costs incurred in producing the item However in the popular
mind this is closely associated with esteem value as there is a mistaken belief that
because something costs more it is worth more Finally there is the resale or exchange
value which may be taken as the ability to part with money for possessing a particular
product In addition we have place value with regard to the usefulness of a product at a
particular place
VARIOUS VALUES CONSIDERED BY VALUE ANALYSEE
1) Huge or functional Value-
It is due to the characteristic quality attributes property of the product by virtue of
which the product performs intended function most satisfactorily with minimum
maintenance
2) Aesthetic Value-
It is due to characteristic attributes property quality because of which product becomes
attractive elegant looking creates sales appeal color shade style texture etc
3) Exchange Value-
It is in terms of the amount of any other commodity that can be obtained in exchange of
the commodity under consideration It depends on time and place
4) Esteem Value-
It is due to special characteristics some manufacturers enjoy customer goodwill and
historical prestige
5) Cost Value-
It is the total of all the costs incurred to manufacture a product ie Unnecessary cost due
to
sect Bad product design
sect Inefficient manufacturing method
sect Inefficient manufacturing processes
sect Lack of Standardization
sect Choose of wrong machine and tools
sect Bad Layout
sect Bad working conditions
sect Accidents to the worker
sect Machine breakdown
sect Bad quality Raw material
sect Lack of training to the workers
sect Excessive variety of products
sect Frequent changes in product design
sect Improper material handling
sect Defective packaging of product
sect Waiting
sect Searching
sect Bad house keeping etc
Benefits of Value Analysis

1048707 Identify and develop strategies to mitigate or avoid risks and the
associated costs
1048707 Identify opportunities which promote Context Sensitive Solutions
1048707 Validate projectrsquos scope need and purpose and baseline design
APPLICATION OF VALUE ANALYSIS
Value analysis can be applied universally ie to everything ndash materials methods
processes services etc where it is intended to bring about economics One should
naturally start with items where the maximum annual saving can be achieved This
immediately suggests that items whose total annual consumption in Rupees is high
should receive top priorities in the application of Value Analysis In the same manner
scarce materials imported materials or those difficult to obtain should also receive the
attention of the value analyst Bearing this in mind Value Analysis can be systematically
applied to categories of items such as those listed below in order to bring about
substantial cost reduction
1 Capital goods ndash plant equipment machinery tools and appliances
2 Raw and semi-processed material including fuel
3 Sub-contracted parts components sub-assemblies etc
4 Purchased parts components sub-assemblies etc
5 Maintenance repairs and operational items
6 Finishing items such as paints oils varnishes etc
7 Packing materials and packaging
8 Printing and Stationery items
9 Miscellaneous items of regular consumptions
10 Power water supply compressed air steam and other utilities
(services) and
11 Materials handling and transportation costs
As mentioned earlier items where the saving can be substantial should obviously
be taken up first Also items which are imported or difficult to obtain and monopoly
items should receive high priority
However even if no economy can be effected immediately by Value Analysis on any
particular item then usefulness of the technique should not be forgotten altogether The
item should be taken up again for value analysis after six months or a year the period
being dictated by the findings of the investigation New ideas may come to your mind at
some other time Also it should be noted that the conditions in the market keep on
changing fast and new materials new suppliers and new processes come into existence
rapidly as a result of phenomenal technological progress taking place at present A
frequent and systematic review of the items already value analyzed with advantage may
result in further economies
ORGANISATION FOR VALUE ANALYSIS
Value analysis is a staff function like for instance Industrial Engineering and should be
organized as much It should be directly under a high-ranking officer from the Senior
Management of an undertaking This is necessary because Value Analysis concerns all
departments and the analyst must have access to them and to their records performance
costs etc Depending upon the size of the undertaking and its scale of operations there
can be a Central Value Analysis Cell to co-ordinate the work of individual analysts
attached to the design purchase production and engineering departments Where there is
only one Value Analyst he may be attached to the Industrial Engineering Department
or to the Purchase Department
Value Analysis is essentially a team effort What particular items to be taken up for value
analysis and what action is to be taken is usually decided by a small committee
comprising representatives from the Design Production Purchase and Accounts
Departments Any other departmental representative can be coopted if and when
necessary
It is the Purchase Manager (or Material Manager) who has to initiate action convene
meetings at regular intervals and see that substantial results are obtained A large share
of the initial phase of the Value Analysis work will be done by the Purchase Manager or
by other departments at his instance It is his responsibility to seek the maximum value
when a product requirement comes upto the point of purchase It is his duty to challenge
wasteful and avoidable costs inherent in the items he is asked to buy It is therefore
inevitable that a large part of whatever Value Analysis work is done is initiated by the
Purchase Manager
WHEN VALUE ANALYSIS
A product goes through 3 stages (1) Developmental (2) Growth and (3) Maturity before
being out of date Consider now the design efforts put on a product At developmental
stages the design effort is the maximum At the growth stage the effort is much less and is
mainly modifications and changes At maturity stage hardly any design attention is
needed The value of the product slowly increases in development and growth stages as
more features are added and desired changes and modifications are effected At maturity
stage the value increases to peak and then slowly starts reduction because of competition
change of customer tastes and other factors till the product falls out and becomes out of
date It is this stage where value analysis can still enhance the value by cost reduction
and lengthen the Maturity period of a product Thus when the design effort is diverted to
other products it is the time for value analysis to be undertaken The success of value
analysis for one product of course be made use of in the design of other products by
development wing
DIFFERENCE BETWEEN VALUE ANLAYSIS AND VALUE ENGINEERING
VALUE VALUE
ANALYSIS ENGINEERING
Indicates application on the product that is into Indicates application on the product at its
manufacturing design stage
All factors come together including workers It is always done by a specific product
subcontractors engineers to make a team with total design (engineers )team
experience and knowledge
It may change the present stage of the product The changes are executed
at the initial stages only
or operation
It is worked out mostly with help of knowledge It requires specific
technical knowledge
and experience
VALUE ANALYSIS JOB PLAN
Several versions of the VA Job Plan can be found in different literature Some give file
others six and yet many other seven phases It is the systematic approach which is more
important to achieve the desired objectives The phases of VA Job Plan are as follows
SELECTION amp ORIENTATION
ANALYSIS
RECORDING IDEAS
SPECULATION
INVESTIGATION
RECOMMENDATION
IMPLEMENTATION
1) SELECTION amp - to select those problems areas ORIENTATION where a potential for
net higher Savings is expected - use the common paretorsquos ABC analysis - general scope
restrictions and aims of the study is defined
2) ANALYSIS - to examine the data at a coordinated syndicate meeting - to appoint a
secretary to record the minutes - to apply the Tests for Value - to propose further actions
3) RECORDING IDEAS - the secretary writes clearly the minutes of the analysis
meeting
and circulates them to syndicate members - it includes the agenda for the next meeting
4) SPECULATION - to hold additional syndicate 64 meetings in order to discuss the
ideas analysed and any new information obtained - to speculate upon practical measures
for reducing costs and increasing value
5) INVESTIGATION - to investigate suggestions for reducing costs and to make them
practical and acceptable - to obtain definite prices and costs in order to estimate savings
accurately
6) RECOMMENDATION - recommended practical savings to management for
implementing - to present the recommendations as a comprehensive report - to appoint a
member to act as an implementation consultant
7) IMPLEMENTATION - to decide on future plans for the company for which the
authority of the management is needed - to implement the recommendations acceptable to
the management
The value of a function can be increased by four methods
1 Decrease the cost while ensuring the same level of performance
2 Enhance the performance at the same cost
3 Decrease the cost and increase the performance
4 Increase both performance and cost ensuring that performance increases more than
the increment in the cost
ORGANISATION FOR VALUE ANALYSIS
Value analysis is a staff function like for instance Industrial Engineering and should be
organized as much It should be directly under a high-ranking officer from the Senior

is initiated by the Purchase Manager
VALUE ENGINEERING
Value engineering is the term applied to value analysis done the design and prototype
stage of a product The potentials of saving are a more in case value analysis is done at
design stage Other advantages is that any changes at this stage are less costly than to
effect the same at a latter stage when the production is in full swing There are a few
limitations however on value engineering work At the design and proto-type stage the
time is rather short since a company wants to put a new product in the market before any
of its competitors can set in and value engineering will have a very short time to apply
their techniques Evaluation of the value at this stage becomes difficult in absence of any
customer reaction and opinion
WHEN VALUE ANALYSIS
A product goes through 3 stages (1) Developmental (2) Growth and (3) Maturity before
being out of date Consider now the design efforts put on a product At developmental
stages the design effort is the maximum At the growth stage the effort is much less and is

CASE STUDY
ldquoCost Reduction of a product throughValue Analysis amp Value Engineeringrdquo
Introduction
The current business scenario is very demanding with a continuous demand from the
market forces to reduce the product price The pricing as demanded by the market forces
the businesses to reduce product development and manufacturing costs to remain
competitive Manufacturing costs of a product can be broadly categorized in the
following heads
bull Raw material
bull Labor
bull Process that is technology driven
Product engineers are constantly faced with the following challenges
bull Reduce production cost
bull Reduce the material cost
Value Analysis amp Value Engineering (VAVE) methods are very important and useful
in driving down the product cost which helps companies retain market share and sustain
their profitability
At QuEST we uncover those projects of our customer which have a good potential to
improve profits QuEST has a team of engineers who specialize in VAVE to achieve cost
reductions of products
A typical VAVE exercise could reduce the total cost of a product by 5-40 The typical
elements of a VAVE exercise are as follows
bull Information Understand the current state of the project and constraints requirements
bull Function Analysis Understand the project from a functional perspective what must
the project do rather than how the project is currently conceived The function describes
what something does and function analysis is the process where the team reviews the
projects functions to determine those that could be improved Function Analysis can be
enhanced through the use of a graphical mapping tool known as the Function Analysis
System Technique (FAST) FAST applies intuitive logic to test functions create a
common language for a team and test the validity of the functions in the project
bull Creative Generate a quantity of ideas related to other ways to perform the functions
bull Evaluation Reduce the quantity of ideas that have been identified to a short list of
ideas with the greatest potential to improve the project and meet the Value Engineering
study objective
bull Development Further analyze and develop the short list of ideas and develop those
with merit into value alternatives
bull Presentation Phase Implementation Present value alternatives to management team
and other project stakeholders or decision makers
5 Typical Flowchart
An example
The approach to a real life problem and the methodology followed by QuEST to reduce
the product cost is demonstrated through the following example
51 Background and Problem statement
One of the customers of QuEST is a leading manufacturer of industrial components for
control applications This unit is very popular in high end applications
The customer wanted to develop a unit that not only costs 25 less but whose
performance exceeds that of the existing product
52 Challenges
bull Redesign of parts considering minimum impact on existing tooling
bull Redesigned modules should enable field replacement
bull LogicSoftware compatibility with field units
bull Ease of assembly
bull Design must match existing housings and connectors
bull No modification of standardized parts in the product family
54 Value Engineering Study
QuEST team captured the detailed requirements of the project from the Voice of
Customer (VOC) during the kick off meeting It helped to identify areas where cost could
be reduced and which functions needed to be improved to provide competitive advantage
The requirements were listed and prioritized as primary and secondary These prioritized
ldquoNeeds and Wantsrdquo were ranked Quality Function Deployment (QFD) tool was used to
prioritize the ldquoHowrsquosrdquo that affected the ldquoNeeds and Wantsrdquo of the customer The
customer also actively participated in this exercise Vital few options were prioritized
from the trivial many Design requirement ranks were sorted in descending order and
those which addressed 70 of the requirements were selected Thus CTQs or
performance characteristics were identified and agreed upon with the customer The team
then carried out the lsquoABC analysisrsquo on the BOM Components with more than 80 of the
product cost were identified
CTQ (Critical to Quality)
Matches basic function and performance characteristics
One to one module replacement
Same Outer dimensions for the modules
LogicSoftware compatibility with field units
No modification in standardized parts in Product family
Design must match existing housings and connectors
Reduce the cost of direct material by 25 or more
Next the VAVE team laid down the Functions of each item of the product for Value
analysis
This enhanced the understanding of the product functionality This also helped to
understand the Form Fit amp Functions of each of the items amp sub-assemblies With this
study the VAVE team had divided the main project into many sub-projects with respect
to subassemblies to have diversified results for subassemblies and parts This function
diagram threw up many questions to the team which enabled them to come up with a
number of new ideas
bull How the Product is sized What design parameters were employed for this product
bull Focus on high cost components and challenge by asking ldquowhy do we need this part and
what value does it provide to our customerrdquo
bull How else we can designmake it
bull Understand design change impact on subassembly or overall product
bull System level appraisal is desirable to consider different methods or concepts for
delivering the same or better value
bull Component level assessment is lookedfor to consider alternate materials processes and
more efficient designs
bull One of the guiding principles of lean design is to ldquoeliminate or standardizerdquo Can a part
be combined with others and thereby be eliminated If not can it be made common with
other parts in the product
without compromising FFF (Form Fit amp Function) This typically provides quick savings
bull Identify and capture all cost reduction opportunities
The team applied the concept of Pugh Matrix for system amp component level Rankings
were discussed with team collated and analyzed for choosing the optimum concepts
Next FMEA was conducted on the selected concepts to further fine tune the results
Failure modes with high Risk Priority Number (RPN) were identified Failure modes
were prioritized and communicated to the designers to address these risks Alternate
solutions and improvement were discussed and finalized 3D solid modeling was done to
visualize the product It also helped to simulate the active and passive conditions of the
product Components were standardized to reduce the part count Simulation and testing
against the CTQs helped to optimize the product for performances Design calculations
were performed to verify the design for gears springs snaps in the plastic members etc
Also the DFMA was conducted on various aspects of the design amp CTQs A detailed
Differential Cost Analysis was conducted with the customer and their suppliers The
result showed significant cost reduction of each part of the product It was observed that
the costs were reduced mainly due to alternate materials usage the process and by
eliminationreplacement of a part by integrating with the adjacent one
Costs of direct material were compared for the original and new design A significant
38 of savings in direct material cost was realized by this project The team also
achieved a reduction of 34 in the part count This has resulted in many intangible
benefits like savings in procurement costs Inspection costs Inventory cost
transportation reduced variation reduced assembly costs amp Time etc
6 Conclusion
QuEST lsquoValue Engineering teamrsquo achieved 38 of savings in direct material cost and
reduced part count by 34 in this project Having a Paint brush does not make one a
painter While we strive to implement the different VAVE tools we realize that the years
of experience in product design amp development is very essential to achieve the desired
objective VAVE tools and techniques if applied properly with trained amp experienced
resources will provide an extremely powerful suite to improve productivity lower cost
improve quality and also shorten the time-to-market

CONCLUSION
Value analysis is a technique with immense possibilities and systematically employed it
can achieve great economies and increased efficiency Although good results have been
obtained in several individual cases in some industries only a large scale and systematic
application of this technique in all industries and in defence production can result in
substantial economies on a national scale
This valuable technique if systematically employed promises rich dividends and
among other things enables greater use of indigenous raw materials and equipment by
import substitution It is therefore of special significance to a developing country like

APPLICATION OF VALUE ANALYSIS
Value analysis can be applied universally ie to everything ndash materials methods
processes services etc where it is intended to bring about economics One should
naturally start with items where the maximum annual saving can be achieved This
immediately suggests that items whose total annual consumption in Rupees is high
should receive top priorities in the application of Value Analysis In the same manner
scarce materials imported materials or those difficult to obtain should also receive the
attention of the value analyst Bearing this in mind Value Analysis can be systematically
applied to categories of items such as those listed below in order to bring about
substantial cost reduction
1 Capital goods ndash plant equipment machinery tools and appliances
2 Raw and semi-processed material including fuel
3 Sub-contracted parts components sub-assemblies etc
4 Purchased parts components sub-assemblies etc
5 Maintenance repairs and operational items
6 Finishing items such as paints oils varnishes etc
7 Packing materials and packaging
8 Printing and Stationery items
9 Miscellaneous items of regular consumptions
10 Power water supply compressed air steam and other utilities
(services) and
11 Materials handling and transportation costs
As mentioned earlier items where the saving can be substantial should obviously
be taken up first Also items which are imported or difficult to obtain and monopoly
items should receive high priority
However even if no economy can be effected immediately by Value Analysis on any
particular item then usefulness of the technique should not be forgotten altogether The
item should be taken up again for value analysis after six months or a year the period
being dictated by the findings of the investigation New ideas may come to your mind at
some other time Also it should be noted that the conditions in the market keep on
changing fast and new materials new suppliers and new processes come into existence
rapidly as a result of phenomenal technological progress taking place at present A
frequent and systematic review of the items already value analyzed with advantage may
result in further economies
ORGANISATION FOR VALUE ANALYSIS
Value analysis is a staff function like for instance Industrial Engineering and should be
organized as much It should be directly under a high-ranking officer from the Senior
Management of an undertaking This is necessary because Value Analysis concerns all
departments and the analyst must have access to them and to their records performance
costs etc Depending upon the size of the undertaking and its scale of operations there
can be a Central Value Analysis Cell to co-ordinate the work of individual analysts
attached to the design purchase production and engineering departments Where there is
only one Value Analyst he may be attached to the Industrial Engineering Department
or to the Purchase Department
Value Analysis is essentially a team effort What particular items to be taken up for value
analysis and what action is to be taken is usually decided by a small committee
comprising representatives from the Design Production Purchase and Accounts
Departments Any other departmental representative can be coopted if and when
necessary
It is the Purchase Manager (or Material Manager) who has to initiate action convene
meetings at regular intervals and see that substantial results are obtained A large share
of the initial phase of the Value Analysis work will be done by the Purchase Manager or
by other departments at his instance It is his responsibility to seek the maximum value
when a product requirement comes upto the point of purchase It is his duty to challenge
wasteful and avoidable costs inherent in the items he is asked to buy It is therefore
inevitable that a large part of whatever Value Analysis work is done is initiated by the
Purchase Manager
WHEN VALUE ANALYSIS
A product goes through 3 stages (1) Developmental (2) Growth and (3) Maturity before
being out of date Consider now the design efforts put on a product At developmental
stages the design effort is the maximum At the growth stage the effort is much less and is
mainly modifications and changes At maturity stage hardly any design attention is
needed The value of the product slowly increases in development and growth stages as
more features are added and desired changes and modifications are effected At maturity
stage the value increases to peak and then slowly starts reduction because of competition
change of customer tastes and other factors till the product falls out and becomes out of
date It is this stage where value analysis can still enhance the value by cost reduction
and lengthen the Maturity period of a product Thus when the design effort is diverted to
other products it is the time for value analysis to be undertaken The success of value
analysis for one product of course be made use of in the design of other products by
development wing

ideas analysed and any new information obtained - to speculate upon practical measures
for reducing costs and increasing value
5) INVESTIGATION - to investigate suggestions for reducing costs and to make them
practical and acceptable - to obtain definite prices and costs in order to estimate savings
accurately
6) RECOMMENDATION - recommended practical savings to management for

The value of a function can be increased by four methods
1 Decrease the cost while ensuring the same level of performance
2 Enhance the performance at the same cost
3 Decrease the cost and increase the performance
4 Increase both performance and cost ensuring that performance increases more than
the increment in the cost

VALUE ENGINEERING
Value engineering is the term applied to value analysis done the design and prototype
stage of a product The potentials of saving are a more in case value analysis is done at
design stage Other advantages is that any changes at this stage are less costly than to
effect the same at a latter stage when the production is in full swing There are a few
limitations however on value engineering work At the design and proto-type stage the
time is rather short since a company wants to put a new product in the market before any
of its competitors can set in and value engineering will have a very short time to apply
their techniques Evaluation of the value at this stage becomes difficult in absence of any
customer reaction and opinion

CASE STUDY
ldquoCost Reduction of a product throughValue Analysis amp Value Engineeringrdquo
Introduction
The current business scenario is very demanding with a continuous demand from the
market forces to reduce the product price The pricing as demanded by the market forces
the businesses to reduce product development and manufacturing costs to remain
competitive Manufacturing costs of a product can be broadly categorized in the
following heads
bull Raw material
bull Labor
bull Process that is technology driven
Product engineers are constantly faced with the following challenges
bull Reduce production cost
bull Reduce the material cost
Value Analysis amp Value Engineering (VAVE) methods are very important and useful
in driving down the product cost which helps companies retain market share and sustain
their profitability
At QuEST we uncover those projects of our customer which have a good potential to
improve profits QuEST has a team of engineers who specialize in VAVE to achieve cost
reductions of products
A typical VAVE exercise could reduce the total cost of a product by 5-40 The typical
elements of a VAVE exercise are as follows
bull Information Understand the current state of the project and constraints requirements
bull Function Analysis Understand the project from a functional perspective what must
the project do rather than how the project is currently conceived The function describes
what something does and function analysis is the process where the team reviews the
projects functions to determine those that could be improved Function Analysis can be
enhanced through the use of a graphical mapping tool known as the Function Analysis
System Technique (FAST) FAST applies intuitive logic to test functions create a
common language for a team and test the validity of the functions in the project
bull Creative Generate a quantity of ideas related to other ways to perform the functions
bull Evaluation Reduce the quantity of ideas that have been identified to a short list of
ideas with the greatest potential to improve the project and meet the Value Engineering
study objective
bull Development Further analyze and develop the short list of ideas and develop those
with merit into value alternatives
bull Presentation Phase Implementation Present value alternatives to management team
and other project stakeholders or decision makers
5 Typical Flowchart
An example
The approach to a real life problem and the methodology followed by QuEST to reduce
the product cost is demonstrated through the following example
51 Background and Problem statement
One of the customers of QuEST is a leading manufacturer of industrial components for
control applications This unit is very popular in high end applications
The customer wanted to develop a unit that not only costs 25 less but whose
performance exceeds that of the existing product
52 Challenges
bull Redesign of parts considering minimum impact on existing tooling
bull Redesigned modules should enable field replacement
bull LogicSoftware compatibility with field units
bull Ease of assembly
bull Design must match existing housings and connectors
bull No modification of standardized parts in the product family
54 Value Engineering Study
QuEST team captured the detailed requirements of the project from the Voice of
Customer (VOC) during the kick off meeting It helped to identify areas where cost could
be reduced and which functions needed to be improved to provide competitive advantage
The requirements were listed and prioritized as primary and secondary These prioritized
ldquoNeeds and Wantsrdquo were ranked Quality Function Deployment (QFD) tool was used to
prioritize the ldquoHowrsquosrdquo that affected the ldquoNeeds and Wantsrdquo of the customer The
customer also actively participated in this exercise Vital few options were prioritized
from the trivial many Design requirement ranks were sorted in descending order and
those which addressed 70 of the requirements were selected Thus CTQs or
performance characteristics were identified and agreed upon with the customer The team
then carried out the lsquoABC analysisrsquo on the BOM Components with more than 80 of the
product cost were identified
CTQ (Critical to Quality)
Matches basic function and performance characteristics
One to one module replacement
Same Outer dimensions for the modules
LogicSoftware compatibility with field units
No modification in standardized parts in Product family
Design must match existing housings and connectors
Reduce the cost of direct material by 25 or more
Next the VAVE team laid down the Functions of each item of the product for Value
analysis
This enhanced the understanding of the product functionality This also helped to
understand the Form Fit amp Functions of each of the items amp sub-assemblies With this
study the VAVE team had divided the main project into many sub-projects with respect
to subassemblies to have diversified results for subassemblies and parts This function
diagram threw up many questions to the team which enabled them to come up with a
number of new ideas
bull How the Product is sized What design parameters were employed for this product
bull Focus on high cost components and challenge by asking ldquowhy do we need this part and
what value does it provide to our customerrdquo
bull How else we can designmake it
bull Understand design change impact on subassembly or overall product
bull System level appraisal is desirable to consider different methods or concepts for
delivering the same or better value
bull Component level assessment is lookedfor to consider alternate materials processes and
more efficient designs
bull One of the guiding principles of lean design is to ldquoeliminate or standardizerdquo Can a part
be combined with others and thereby be eliminated If not can it be made common with
other parts in the product
without compromising FFF (Form Fit amp Function) This typically provides quick savings
bull Identify and capture all cost reduction opportunities
The team applied the concept of Pugh Matrix for system amp component level Rankings
were discussed with team collated and analyzed for choosing the optimum concepts
Next FMEA was conducted on the selected concepts to further fine tune the results
Failure modes with high Risk Priority Number (RPN) were identified Failure modes
were prioritized and communicated to the designers to address these risks Alternate
solutions and improvement were discussed and finalized 3D solid modeling was done to
visualize the product It also helped to simulate the active and passive conditions of the
product Components were standardized to reduce the part count Simulation and testing
against the CTQs helped to optimize the product for performances Design calculations
were performed to verify the design for gears springs snaps in the plastic members etc
Also the DFMA was conducted on various aspects of the design amp CTQs A detailed
Differential Cost Analysis was conducted with the customer and their suppliers The
result showed significant cost reduction of each part of the product It was observed that
the costs were reduced mainly due to alternate materials usage the process and by
eliminationreplacement of a part by integrating with the adjacent one
Costs of direct material were compared for the original and new design A significant
38 of savings in direct material cost was realized by this project The team also
achieved a reduction of 34 in the part count This has resulted in many intangible
benefits like savings in procurement costs Inspection costs Inventory cost
transportation reduced variation reduced assembly costs amp Time etc
6 Conclusion
QuEST lsquoValue Engineering teamrsquo achieved 38 of savings in direct material cost and
reduced part count by 34 in this project Having a Paint brush does not make one a
painter While we strive to implement the different VAVE tools we realize that the years
of experience in product design amp development is very essential to achieve the desired
objective VAVE tools and techniques if applied properly with trained amp experienced
resources will provide an extremely powerful suite to improve productivity lower cost
improve quality and also shorten the time-to-market

CONCLUSION
Value analysis is a technique with immense possibilities and systematically employed it
can achieve great economies and increased efficiency Although good results have been
obtained in several individual cases in some industries only a large scale and systematic
application of this technique in all industries and in defence production can result in
substantial economies on a national scale
This valuable technique if systematically employed promises rich dividends and
among other things enables greater use of indigenous raw materials and equipment by
import substitution It is therefore of special significance to a developing country like
India which has adopted a programme of rapid industrialization in the face of paucity of
foreign exchange and other handicaps
No Company can take seriously Total Quality Management without operating a
formalized system of Value Analysis No business that wishes to become lean will ever
succeed if product designs remain unchanged because no amount of continuous
improvement in the manufacturing process can release the costs of a poor design or a
design that has not changed for many years
However poor product reviews or an informal process that is restricted to only to a
review of the design by the design department will yield only limited success in
eliminating lsquoavoidable costsrsquo These efforts will miss the many opportunities to make
manufacturing and assembly easier quicker less complex and less costly Thus margins
will not be improved significantly because only a small part of the total process has been
managed correctly As such this type of superficial activity will not generate increased
profit and the revenue stream that will be needed to finance new products and new
investments in technology A properly managed and effective VA process will easily
repay the time invested by managers over the life of the product and a truly effective
process will yield significant competitive advantage for companies that exploit it For
businesses that supply other organizations the ability to design and redesign products
opens the possibility of true meaningful profitable and long-term partnership with a
customer Each progressive step that secures a greater design responsibility for the
supplier will in parallel make the supplier increasingly more important to the
competitive advantage of the customer organization and will increase the benefits to both
companies In an environment where budgets are often reduced the market determines
the selling price of a product and consumers demand a greater variety of products VA is
one technique that companies cannot afford to ignore because for every day that the
technique is not employed is money that will leave the business forever Money that
cannot be recovered once the product has been sold
The benefits of a formalized and effective VA process are therefore many and include
some key sources of competitive advantage for any business including
bull Speed of getting an effective design into the market without problems and through
error-free manufacturing and assembly processes
bull Reliability and durability of the product in the market which enhances the reputation
of the product and the company
bull Low overall cost which enhances product margin and also releases finances within the
business as well as allowing the ability to engage in price competition
bull Enhanced quality and compliance with minimal costs of warranty that allows a
company to differentiate its products based this perceived quality (of use and esteem)
bull Differentiation by creating product designs as platforms which facilitate lsquolast
minutersquo or late configuration of the product to meet customer orders regional preferences
or any other geographical constraint (such as product laws of a certain region)
bull Finally the VA process satisfies the primary goal of any business ndash to make a profit
and survive
As a process VA is very robust and offers tangible financial and people-based benefits
The process eliminates unnecessary weight it removes unnecessary costs and importantly
it allows people to understand products processes and continuous improvement Very
few modern management techniques allow this form of participation and involvement
and even fewer have such a profound impact on the bottom line of the businessrsquos trading
accounts For companies that do not employ this technique there is one very frightening
thought that for every product that the company makes one or two may be bought by
competitors and subjected to value analysis Therefore these competitors can easily
recover the ground lost to any lsquobreakthroughrsquo new product with half the effort and half
the expense of starting from the beginning These competitors can also take the new
product and lsquostreamlinersquo it to offer maximum value at minimum cost thereby creating a
new product without any real expense This is perhaps the most frightening though of all

item and from its ability to perform a useful function reliable There is the subjective
aspect of value in terms of esteem or prestige value or artistic value for example the
extra chrome 63 and styling used to sell automobiles or the neck-tie or diamond ring you
may wear Again there is the cost value made up of the material and labour costs
overheads and any other costs incurred in producing the item However in the popular
mind this is closely associated with esteem value as there is a mistaken belief that
because something costs more it is worth more Finally there is the resale or exchange
value which may be taken as the ability to part with money for possessing a particular
product In addition we have place value with regard to the usefulness of a product at a
particular place
VARIOUS VALUES CONSIDERED BY VALUE ANALYSEE
1) Huge or functional Value-
It is due to the characteristic quality attributes property of the product by virtue of
which the product performs intended function most satisfactorily with minimum
maintenance
2) Aesthetic Value-
It is due to characteristic attributes property quality because of which product becomes
attractive elegant looking creates sales appeal color shade style texture etc
3) Exchange Value-
It is in terms of the amount of any other commodity that can be obtained in exchange of
the commodity under consideration It depends on time and place
4) Esteem Value-
It is due to special characteristics some manufacturers enjoy customer goodwill and
historical prestige
5) Cost Value-
It is the total of all the costs incurred to manufacture a product ie Unnecessary cost due
to
sect Bad product design
sect Inefficient manufacturing method
sect Inefficient manufacturing processes
sect Lack of Standardization
sect Choose of wrong machine and tools
sect Bad Layout
sect Bad working conditions
sect Accidents to the worker
sect Machine breakdown
sect Bad quality Raw material
sect Lack of training to the workers
sect Excessive variety of products
sect Frequent changes in product design
sect Improper material handling
sect Defective packaging of product
sect Waiting
sect Searching
sect Bad house keeping etc

naturally start with items where the maximum annual saving can be achieved This
immediately suggests that items whose total annual consumption in Rupees is high
should receive top priorities in the application of Value Analysis In the same manner
scarce materials imported materials or those difficult to obtain should also receive the

applied to categories of items such as those listed below in order to bring about
substantial cost reduction
1 Capital goods ndash plant equipment machinery tools and appliances
2 Raw and semi-processed material including fuel
3 Sub-contracted parts components sub-assemblies etc
4 Purchased parts components sub-assemblies etc
5 Maintenance repairs and operational items
6 Finishing items such as paints oils varnishes etc
7 Packing materials and packaging
8 Printing and Stationery items
9 Miscellaneous items of regular consumptions
10 Power water supply compressed air steam and other utilities
(services) and
11 Materials handling and transportation costs
As mentioned earlier items where the saving can be substantial should obviously
be taken up first Also items which are imported or difficult to obtain and monopoly
items should receive high priority
However even if no economy can be effected immediately by Value Analysis on any
particular item then usefulness of the technique should not be forgotten altogether The
item should be taken up again for value analysis after six months or a year the period
being dictated by the findings of the investigation New ideas may come to your mind at
some other time Also it should be noted that the conditions in the market keep on
changing fast and new materials new suppliers and new processes come into existence
rapidly as a result of phenomenal technological progress taking place at present A
frequent and systematic review of the items already value analyzed with advantage may
result in further economies
ORGANISATION FOR VALUE ANALYSIS
Value analysis is a staff function like for instance Industrial Engineering and should be
organized as much It should be directly under a high-ranking officer from the Senior
Management of an undertaking This is necessary because Value Analysis concerns all
departments and the analyst must have access to them and to their records performance
costs etc Depending upon the size of the undertaking and its scale of operations there
can be a Central Value Analysis Cell to co-ordinate the work of individual analysts
attached to the design purchase production and engineering departments Where there is
only one Value Analyst he may be attached to the Industrial Engineering Department
or to the Purchase Department
Value Analysis is essentially a team effort What particular items to be taken up for value
analysis and what action is to be taken is usually decided by a small committee
comprising representatives from the Design Production Purchase and Accounts
Departments Any other departmental representative can be coopted if and when
necessary
It is the Purchase Manager (or Material Manager) who has to initiate action convene
meetings at regular intervals and see that substantial results are obtained A large share
of the initial phase of the Value Analysis work will be done by the Purchase Manager or
by other departments at his instance It is his responsibility to seek the maximum value
when a product requirement comes upto the point of purchase It is his duty to challenge
wasteful and avoidable costs inherent in the items he is asked to buy It is therefore
inevitable that a large part of whatever Value Analysis work is done is initiated by the
Purchase Manager
WHEN VALUE ANALYSIS
A product goes through 3 stages (1) Developmental (2) Growth and (3) Maturity before
being out of date Consider now the design efforts put on a product At developmental
stages the design effort is the maximum At the growth stage the effort is much less and is
mainly modifications and changes At maturity stage hardly any design attention is

more features are added and desired changes and modifications are effected At maturity
stage the value increases to peak and then slowly starts reduction because of competition
change of customer tastes and other factors till the product falls out and becomes out of
date It is this stage where value analysis can still enhance the value by cost reduction
and lengthen the Maturity period of a product Thus when the design effort is diverted to
other products it is the time for value analysis to be undertaken The success of value

Introduction
The current business scenario is very demanding with a continuous demand from the
market forces to reduce the product price The pricing as demanded by the market forces
the businesses to reduce product development and manufacturing costs to remain
competitive Manufacturing costs of a product can be broadly categorized in the
following heads
bull Raw material
bull Labor
bull Process that is technology driven
Product engineers are constantly faced with the following challenges
bull Reduce production cost
bull Reduce the material cost
Value Analysis amp Value Engineering (VAVE) methods are very important and useful
in driving down the product cost which helps companies retain market share and sustain
their profitability
At QuEST we uncover those projects of our customer which have a good potential to
improve profits QuEST has a team of engineers who specialize in VAVE to achieve cost
reductions of products
A typical VAVE exercise could reduce the total cost of a product by 5-40 The typical
elements of a VAVE exercise are as follows
bull Information Understand the current state of the project and constraints requirements
bull Function Analysis Understand the project from a functional perspective what must
the project do rather than how the project is currently conceived The function describes
what something does and function analysis is the process where the team reviews the
projects functions to determine those that could be improved Function Analysis can be
enhanced through the use of a graphical mapping tool known as the Function Analysis
System Technique (FAST) FAST applies intuitive logic to test functions create a
common language for a team and test the validity of the functions in the project
bull Creative Generate a quantity of ideas related to other ways to perform the functions
bull Evaluation Reduce the quantity of ideas that have been identified to a short list of
ideas with the greatest potential to improve the project and meet the Value Engineering
study objective
bull Development Further analyze and develop the short list of ideas and develop those
with merit into value alternatives
bull Presentation Phase Implementation Present value alternatives to management team
and other project stakeholders or decision makers
5 Typical Flowchart
An example
The approach to a real life problem and the methodology followed by QuEST to reduce
the product cost is demonstrated through the following example
51 Background and Problem statement
One of the customers of QuEST is a leading manufacturer of industrial components for
control applications This unit is very popular in high end applications
The customer wanted to develop a unit that not only costs 25 less but whose
performance exceeds that of the existing product
52 Challenges
bull Redesign of parts considering minimum impact on existing tooling
bull Redesigned modules should enable field replacement
bull LogicSoftware compatibility with field units
bull Ease of assembly
bull Design must match existing housings and connectors
bull No modification of standardized parts in the product family
54 Value Engineering Study
QuEST team captured the detailed requirements of the project from the Voice of
Customer (VOC) during the kick off meeting It helped to identify areas where cost could
be reduced and which functions needed to be improved to provide competitive advantage
The requirements were listed and prioritized as primary and secondary These prioritized
ldquoNeeds and Wantsrdquo were ranked Quality Function Deployment (QFD) tool was used to
prioritize the ldquoHowrsquosrdquo that affected the ldquoNeeds and Wantsrdquo of the customer The
customer also actively participated in this exercise Vital few options were prioritized
from the trivial many Design requirement ranks were sorted in descending order and
those which addressed 70 of the requirements were selected Thus CTQs or
performance characteristics were identified and agreed upon with the customer The team
then carried out the lsquoABC analysisrsquo on the BOM Components with more than 80 of the
product cost were identified
CTQ (Critical to Quality)
Matches basic function and performance characteristics
One to one module replacement
Same Outer dimensions for the modules
LogicSoftware compatibility with field units
No modification in standardized parts in Product family
Design must match existing housings and connectors
Reduce the cost of direct material by 25 or more
Next the VAVE team laid down the Functions of each item of the product for Value
analysis
This enhanced the understanding of the product functionality This also helped to
understand the Form Fit amp Functions of each of the items amp sub-assemblies With this
study the VAVE team had divided the main project into many sub-projects with respect
to subassemblies to have diversified results for subassemblies and parts This function
diagram threw up many questions to the team which enabled them to come up with a
number of new ideas
bull How the Product is sized What design parameters were employed for this product
bull Focus on high cost components and challenge by asking ldquowhy do we need this part and
what value does it provide to our customerrdquo
bull How else we can designmake it
bull Understand design change impact on subassembly or overall product
bull System level appraisal is desirable to consider different methods or concepts for
delivering the same or better value
bull Component level assessment is lookedfor to consider alternate materials processes and
more efficient designs
bull One of the guiding principles of lean design is to ldquoeliminate or standardizerdquo Can a part
be combined with others and thereby be eliminated If not can it be made common with
other parts in the product
without compromising FFF (Form Fit amp Function) This typically provides quick savings
bull Identify and capture all cost reduction opportunities
The team applied the concept of Pugh Matrix for system amp component level Rankings
were discussed with team collated and analyzed for choosing the optimum concepts
Next FMEA was conducted on the selected concepts to further fine tune the results
Failure modes with high Risk Priority Number (RPN) were identified Failure modes
were prioritized and communicated to the designers to address these risks Alternate
solutions and improvement were discussed and finalized 3D solid modeling was done to
visualize the product It also helped to simulate the active and passive conditions of the
product Components were standardized to reduce the part count Simulation and testing
against the CTQs helped to optimize the product for performances Design calculations
were performed to verify the design for gears springs snaps in the plastic members etc
Also the DFMA was conducted on various aspects of the design amp CTQs A detailed
Differential Cost Analysis was conducted with the customer and their suppliers The
result showed significant cost reduction of each part of the product It was observed that
the costs were reduced mainly due to alternate materials usage the process and by
eliminationreplacement of a part by integrating with the adjacent one
Costs of direct material were compared for the original and new design A significant
38 of savings in direct material cost was realized by this project The team also
achieved a reduction of 34 in the part count This has resulted in many intangible
benefits like savings in procurement costs Inspection costs Inventory cost
transportation reduced variation reduced assembly costs amp Time etc
6 Conclusion
QuEST lsquoValue Engineering teamrsquo achieved 38 of savings in direct material cost and
reduced part count by 34 in this project Having a Paint brush does not make one a
painter While we strive to implement the different VAVE tools we realize that the years
of experience in product design amp development is very essential to achieve the desired
objective VAVE tools and techniques if applied properly with trained amp experienced
resources will provide an extremely powerful suite to improve productivity lower cost
improve quality and also shorten the time-to-market

CONCLUSION
Value analysis is a technique with immense possibilities and systematically employed it
can achieve great economies and increased efficiency Although good results have been
obtained in several individual cases in some industries only a large scale and systematic
application of this technique in all industries and in defence production can result in
substantial economies on a national scale
This valuable technique if systematically employed promises rich dividends and
among other things enables greater use of indigenous raw materials and equipment by
import substitution It is therefore of special significance to a developing country like
India which has adopted a programme of rapid industrialization in the face of paucity of
foreign exchange and other handicaps
No Company can take seriously Total Quality Management without operating a
formalized system of Value Analysis No business that wishes to become lean will ever
succeed if product designs remain unchanged because no amount of continuous
improvement in the manufacturing process can release the costs of a poor design or a
design that has not changed for many years
However poor product reviews or an informal process that is restricted to only to a
review of the design by the design department will yield only limited success in
eliminating lsquoavoidable costsrsquo These efforts will miss the many opportunities to make
manufacturing and assembly easier quicker less complex and less costly Thus margins
will not be improved significantly because only a small part of the total process has been
managed correctly As such this type of superficial activity will not generate increased
profit and the revenue stream that will be needed to finance new products and new
investments in technology A properly managed and effective VA process will easily
repay the time invested by managers over the life of the product and a truly effective
process will yield significant competitive advantage for companies that exploit it For
businesses that supply other organizations the ability to design and redesign products
opens the possibility of true meaningful profitable and long-term partnership with a
customer Each progressive step that secures a greater design responsibility for the
supplier will in parallel make the supplier increasingly more important to the
competitive advantage of the customer organization and will increase the benefits to both
companies In an environment where budgets are often reduced the market determines
the selling price of a product and consumers demand a greater variety of products VA is
one technique that companies cannot afford to ignore because for every day that the
technique is not employed is money that will leave the business forever Money that
cannot be recovered once the product has been sold
The benefits of a formalized and effective VA process are therefore many and include
some key sources of competitive advantage for any business including
bull Speed of getting an effective design into the market without problems and through
error-free manufacturing and assembly processes
bull Reliability and durability of the product in the market which enhances the reputation
of the product and the company
bull Low overall cost which enhances product margin and also releases finances within the
business as well as allowing the ability to engage in price competition
bull Enhanced quality and compliance with minimal costs of warranty that allows a
company to differentiate its products based this perceived quality (of use and esteem)
bull Differentiation by creating product designs as platforms which facilitate lsquolast
minutersquo or late configuration of the product to meet customer orders regional preferences
or any other geographical constraint (such as product laws of a certain region)
bull Finally the VA process satisfies the primary goal of any business ndash to make a profit
and survive
As a process VA is very robust and offers tangible financial and people-based benefits
The process eliminates unnecessary weight it removes unnecessary costs and importantly
it allows people to understand products processes and continuous improvement Very
few modern management techniques allow this form of participation and involvement
and even fewer have such a profound impact on the bottom line of the businessrsquos trading
accounts For companies that do not employ this technique there is one very frightening
thought that for every product that the company makes one or two may be bought by
competitors and subjected to value analysis Therefore these competitors can easily
recover the ground lost to any lsquobreakthroughrsquo new product with half the effort and half
the expense of starting from the beginning These competitors can also take the new
product and lsquostreamlinersquo it to offer maximum value at minimum cost thereby creating a
new product without any real expense This is perhaps the most frightening though of all

1048707 Identify and develop strategies to mitigate or avoid risks and the
associated costs
1048707 Identify opportunities which promote Context Sensitive Solutions
1048707 Validate projectrsquos scope need and purpose and baseline design
APPLICATION OF VALUE ANALYSIS
Value analysis can be applied universally ie to everything ndash materials methods
processes services etc where it is intended to bring about economics One should
naturally start with items where the maximum annual saving can be achieved This
immediately suggests that items whose total annual consumption in Rupees is high
should receive top priorities in the application of Value Analysis In the same manner
scarce materials imported materials or those difficult to obtain should also receive the
attention of the value analyst Bearing this in mind Value Analysis can be systematically
applied to categories of items such as those listed below in order to bring about
substantial cost reduction
1 Capital goods ndash plant equipment machinery tools and appliances
2 Raw and semi-processed material including fuel
3 Sub-contracted parts components sub-assemblies etc
4 Purchased parts components sub-assemblies etc
5 Maintenance repairs and operational items
6 Finishing items such as paints oils varnishes etc
7 Packing materials and packaging
8 Printing and Stationery items
9 Miscellaneous items of regular consumptions
10 Power water supply compressed air steam and other utilities
(services) and
11 Materials handling and transportation costs
As mentioned earlier items where the saving can be substantial should obviously
be taken up first Also items which are imported or difficult to obtain and monopoly
items should receive high priority
However even if no economy can be effected immediately by Value Analysis on any
particular item then usefulness of the technique should not be forgotten altogether The
item should be taken up again for value analysis after six months or a year the period
being dictated by the findings of the investigation New ideas may come to your mind at
some other time Also it should be noted that the conditions in the market keep on
changing fast and new materials new suppliers and new processes come into existence
rapidly as a result of phenomenal technological progress taking place at present A
frequent and systematic review of the items already value analyzed with advantage may
result in further economies
ORGANISATION FOR VALUE ANALYSIS
Value analysis is a staff function like for instance Industrial Engineering and should be
organized as much It should be directly under a high-ranking officer from the Senior
Management of an undertaking This is necessary because Value Analysis concerns all
departments and the analyst must have access to them and to their records performance
costs etc Depending upon the size of the undertaking and its scale of operations there
can be a Central Value Analysis Cell to co-ordinate the work of individual analysts
attached to the design purchase production and engineering departments Where there is
only one Value Analyst he may be attached to the Industrial Engineering Department
or to the Purchase Department
Value Analysis is essentially a team effort What particular items to be taken up for value
analysis and what action is to be taken is usually decided by a small committee
comprising representatives from the Design Production Purchase and Accounts
Departments Any other departmental representative can be coopted if and when
necessary
It is the Purchase Manager (or Material Manager) who has to initiate action convene
meetings at regular intervals and see that substantial results are obtained A large share
of the initial phase of the Value Analysis work will be done by the Purchase Manager or
by other departments at his instance It is his responsibility to seek the maximum value
when a product requirement comes upto the point of purchase It is his duty to challenge
wasteful and avoidable costs inherent in the items he is asked to buy It is therefore
inevitable that a large part of whatever Value Analysis work is done is initiated by the
Purchase Manager
WHEN VALUE ANALYSIS
A product goes through 3 stages (1) Developmental (2) Growth and (3) Maturity before
being out of date Consider now the design efforts put on a product At developmental
stages the design effort is the maximum At the growth stage the effort is much less and is
mainly modifications and changes At maturity stage hardly any design attention is
needed The value of the product slowly increases in development and growth stages as
more features are added and desired changes and modifications are effected At maturity
stage the value increases to peak and then slowly starts reduction because of competition
change of customer tastes and other factors till the product falls out and becomes out of
date It is this stage where value analysis can still enhance the value by cost reduction
and lengthen the Maturity period of a product Thus when the design effort is diverted to
other products it is the time for value analysis to be undertaken The success of value
analysis for one product of course be made use of in the design of other products by
development wing
DIFFERENCE BETWEEN VALUE ANLAYSIS AND VALUE ENGINEERING

Indicates application on the product that is into Indicates application on the product at its
manufacturing design stage
All factors come together including workers It is always done by a specific product
subcontractors engineers to make a team with total design (engineers )team
experience and knowledge
It may change the present stage of the product The changes are executed
at the initial stages only
or operation
It is worked out mostly with help of knowledge It requires specific
technical knowledge
and experience
VALUE ANALYSIS JOB PLAN
Several versions of the VA Job Plan can be found in different literature Some give file
others six and yet many other seven phases It is the systematic approach which is more
important to achieve the desired objectives The phases of VA Job Plan are as follows
SELECTION amp ORIENTATION
ANALYSIS
RECORDING IDEAS
SPECULATION
INVESTIGATION
RECOMMENDATION
IMPLEMENTATION
1) SELECTION amp - to select those problems areas ORIENTATION where a potential for
net higher Savings is expected - use the common paretorsquos ABC analysis - general scope
restrictions and aims of the study is defined
2) ANALYSIS - to examine the data at a coordinated syndicate meeting - to appoint a
secretary to record the minutes - to apply the Tests for Value - to propose further actions
3) RECORDING IDEAS - the secretary writes clearly the minutes of the analysis
meeting
and circulates them to syndicate members - it includes the agenda for the next meeting
4) SPECULATION - to hold additional syndicate 64 meetings in order to discuss the
ideas analysed and any new information obtained - to speculate upon practical measures
for reducing costs and increasing value
5) INVESTIGATION - to investigate suggestions for reducing costs and to make them
practical and acceptable - to obtain definite prices and costs in order to estimate savings
accurately
6) RECOMMENDATION - recommended practical savings to management for
implementing - to present the recommendations as a comprehensive report - to appoint a
member to act as an implementation consultant
7) IMPLEMENTATION - to decide on future plans for the company for which the
authority of the management is needed - to implement the recommendations acceptable to
the management
The value of a function can be increased by four methods
1 Decrease the cost while ensuring the same level of performance
2 Enhance the performance at the same cost
3 Decrease the cost and increase the performance
4 Increase both performance and cost ensuring that performance increases more than
the increment in the cost
ORGANISATION FOR VALUE ANALYSIS
Value analysis is a staff function like for instance Industrial Engineering and should be
organized as much It should be directly under a high-ranking officer from the Senior
Management of an undertaking This is necessary because Value Analysis concerns all

is initiated by the Purchase Manager
VALUE ENGINEERING
Value engineering is the term applied to value analysis done the design and prototype
stage of a product The potentials of saving are a more in case value analysis is done at
design stage Other advantages is that any changes at this stage are less costly than to
effect the same at a latter stage when the production is in full swing There are a few
limitations however on value engineering work At the design and proto-type stage the
time is rather short since a company wants to put a new product in the market before any
of its competitors can set in and value engineering will have a very short time to apply
their techniques Evaluation of the value at this stage becomes difficult in absence of any
customer reaction and opinion
WHEN VALUE ANALYSIS
A product goes through 3 stages (1) Developmental (2) Growth and (3) Maturity before
being out of date Consider now the design efforts put on a product At developmental
stages the design effort is the maximum At the growth stage the effort is much less and is

APPLICATION OF VALUE ANALYSIS
Value analysis can be applied universally ie to everything ndash materials methods
processes services etc where it is intended to bring about economics One should
naturally start with items where the maximum annual saving can be achieved This
immediately suggests that items whose total annual consumption in Rupees is high
should receive top priorities in the application of Value Analysis In the same manner
scarce materials imported materials or those difficult to obtain should also receive the
attention of the value analyst Bearing this in mind Value Analysis can be systematically
applied to categories of items such as those listed below in order to bring about
substantial cost reduction
1 Capital goods ndash plant equipment machinery tools and appliances
2 Raw and semi-processed material including fuel
3 Sub-contracted parts components sub-assemblies etc
4 Purchased parts components sub-assemblies etc
5 Maintenance repairs and operational items
6 Finishing items such as paints oils varnishes etc
7 Packing materials and packaging
8 Printing and Stationery items
9 Miscellaneous items of regular consumptions
10 Power water supply compressed air steam and other utilities
(services) and
11 Materials handling and transportation costs
As mentioned earlier items where the saving can be substantial should obviously
be taken up first Also items which are imported or difficult to obtain and monopoly
items should receive high priority
However even if no economy can be effected immediately by Value Analysis on any
particular item then usefulness of the technique should not be forgotten altogether The
item should be taken up again for value analysis after six months or a year the period
being dictated by the findings of the investigation New ideas may come to your mind at
some other time Also it should be noted that the conditions in the market keep on
changing fast and new materials new suppliers and new processes come into existence
rapidly as a result of phenomenal technological progress taking place at present A
frequent and systematic review of the items already value analyzed with advantage may
result in further economies
ORGANISATION FOR VALUE ANALYSIS
Value analysis is a staff function like for instance Industrial Engineering and should be
organized as much It should be directly under a high-ranking officer from the Senior
Management of an undertaking This is necessary because Value Analysis concerns all
departments and the analyst must have access to them and to their records performance
costs etc Depending upon the size of the undertaking and its scale of operations there
can be a Central Value Analysis Cell to co-ordinate the work of individual analysts
attached to the design purchase production and engineering departments Where there is
only one Value Analyst he may be attached to the Industrial Engineering Department
or to the Purchase Department
Value Analysis is essentially a team effort What particular items to be taken up for value
analysis and what action is to be taken is usually decided by a small committee
comprising representatives from the Design Production Purchase and Accounts
Departments Any other departmental representative can be coopted if and when
necessary
It is the Purchase Manager (or Material Manager) who has to initiate action convene
meetings at regular intervals and see that substantial results are obtained A large share
of the initial phase of the Value Analysis work will be done by the Purchase Manager or
by other departments at his instance It is his responsibility to seek the maximum value
when a product requirement comes upto the point of purchase It is his duty to challenge
wasteful and avoidable costs inherent in the items he is asked to buy It is therefore
inevitable that a large part of whatever Value Analysis work is done is initiated by the
Purchase Manager
WHEN VALUE ANALYSIS
A product goes through 3 stages (1) Developmental (2) Growth and (3) Maturity before
being out of date Consider now the design efforts put on a product At developmental
stages the design effort is the maximum At the growth stage the effort is much less and is
mainly modifications and changes At maturity stage hardly any design attention is
needed The value of the product slowly increases in development and growth stages as
more features are added and desired changes and modifications are effected At maturity
stage the value increases to peak and then slowly starts reduction because of competition
change of customer tastes and other factors till the product falls out and becomes out of
date It is this stage where value analysis can still enhance the value by cost reduction
and lengthen the Maturity period of a product Thus when the design effort is diverted to
other products it is the time for value analysis to be undertaken The success of value
analysis for one product of course be made use of in the design of other products by
development wing

VALUE ANALYSIS JOB PLAN
Several versions of the VA Job Plan can be found in different literature Some give file
others six and yet many other seven phases It is the systematic approach which is more
important to achieve the desired objectives The phases of VA Job Plan are as follows
SELECTION amp ORIENTATION

RECORDING IDEAS
SPECULATION
INVESTIGATION
RECOMMENDATION
IMPLEMENTATION
1) SELECTION amp - to select those problems areas ORIENTATION where a potential for
net higher Savings is expected - use the common paretorsquos ABC analysis - general scope
restrictions and aims of the study is defined
2) ANALYSIS - to examine the data at a coordinated syndicate meeting - to appoint a
secretary to record the minutes - to apply the Tests for Value - to propose further actions
3) RECORDING IDEAS - the secretary writes clearly the minutes of the analysis
meeting
and circulates them to syndicate members - it includes the agenda for the next meeting
4) SPECULATION - to hold additional syndicate 64 meetings in order to discuss the
ideas analysed and any new information obtained - to speculate upon practical measures
for reducing costs and increasing value
5) INVESTIGATION - to investigate suggestions for reducing costs and to make them
practical and acceptable - to obtain definite prices and costs in order to estimate savings
accurately
6) RECOMMENDATION - recommended practical savings to management for
implementing - to present the recommendations as a comprehensive report - to appoint a
member to act as an implementation consultant
7) IMPLEMENTATION - to decide on future plans for the company for which the
authority of the management is needed - to implement the recommendations acceptable to
the management
The value of a function can be increased by four methods
1 Decrease the cost while ensuring the same level of performance
2 Enhance the performance at the same cost
3 Decrease the cost and increase the performance
4 Increase both performance and cost ensuring that performance increases more than
the increment in the cost

VALUE ENGINEERING
Value engineering is the term applied to value analysis done the design and prototype
stage of a product The potentials of saving are a more in case value analysis is done at
design stage Other advantages is that any changes at this stage are less costly than to
effect the same at a latter stage when the production is in full swing There are a few
limitations however on value engineering work At the design and proto-type stage the
time is rather short since a company wants to put a new product in the market before any
of its competitors can set in and value engineering will have a very short time to apply
their techniques Evaluation of the value at this stage becomes difficult in absence of any
customer reaction and opinion
WHEN VALUE ANALYSIS

CASE STUDY
ldquoCost Reduction of a product throughValue Analysis amp Value Engineeringrdquo
Introduction
The current business scenario is very demanding with a continuous demand from the
market forces to reduce the product price The pricing as demanded by the market forces
the businesses to reduce product development and manufacturing costs to remain
competitive Manufacturing costs of a product can be broadly categorized in the
following heads
bull Raw material
bull Labor
bull Process that is technology driven
Product engineers are constantly faced with the following challenges
bull Reduce production cost
bull Reduce the material cost
Value Analysis amp Value Engineering (VAVE) methods are very important and useful
in driving down the product cost which helps companies retain market share and sustain
their profitability
At QuEST we uncover those projects of our customer which have a good potential to
improve profits QuEST has a team of engineers who specialize in VAVE to achieve cost
reductions of products
A typical VAVE exercise could reduce the total cost of a product by 5-40 The typical
elements of a VAVE exercise are as follows
bull Information Understand the current state of the project and constraints requirements
bull Function Analysis Understand the project from a functional perspective what must
the project do rather than how the project is currently conceived The function describes
what something does and function analysis is the process where the team reviews the
projects functions to determine those that could be improved Function Analysis can be
enhanced through the use of a graphical mapping tool known as the Function Analysis
System Technique (FAST) FAST applies intuitive logic to test functions create a
common language for a team and test the validity of the functions in the project
bull Creative Generate a quantity of ideas related to other ways to perform the functions
bull Evaluation Reduce the quantity of ideas that have been identified to a short list of
ideas with the greatest potential to improve the project and meet the Value Engineering
study objective
bull Development Further analyze and develop the short list of ideas and develop those
with merit into value alternatives
bull Presentation Phase Implementation Present value alternatives to management team
and other project stakeholders or decision makers
5 Typical Flowchart
An example
The approach to a real life problem and the methodology followed by QuEST to reduce
the product cost is demonstrated through the following example
51 Background and Problem statement
One of the customers of QuEST is a leading manufacturer of industrial components for
control applications This unit is very popular in high end applications
The customer wanted to develop a unit that not only costs 25 less but whose
performance exceeds that of the existing product
52 Challenges
bull Redesign of parts considering minimum impact on existing tooling
bull Redesigned modules should enable field replacement
bull LogicSoftware compatibility with field units
bull Ease of assembly
bull Design must match existing housings and connectors
bull No modification of standardized parts in the product family
54 Value Engineering Study
QuEST team captured the detailed requirements of the project from the Voice of
Customer (VOC) during the kick off meeting It helped to identify areas where cost could
be reduced and which functions needed to be improved to provide competitive advantage
The requirements were listed and prioritized as primary and secondary These prioritized
ldquoNeeds and Wantsrdquo were ranked Quality Function Deployment (QFD) tool was used to
prioritize the ldquoHowrsquosrdquo that affected the ldquoNeeds and Wantsrdquo of the customer The
customer also actively participated in this exercise Vital few options were prioritized
from the trivial many Design requirement ranks were sorted in descending order and
those which addressed 70 of the requirements were selected Thus CTQs or
performance characteristics were identified and agreed upon with the customer The team
then carried out the lsquoABC analysisrsquo on the BOM Components with more than 80 of the
product cost were identified
CTQ (Critical to Quality)
Matches basic function and performance characteristics
One to one module replacement
Same Outer dimensions for the modules
LogicSoftware compatibility with field units
No modification in standardized parts in Product family
Design must match existing housings and connectors
Reduce the cost of direct material by 25 or more
Next the VAVE team laid down the Functions of each item of the product for Value
analysis
This enhanced the understanding of the product functionality This also helped to
understand the Form Fit amp Functions of each of the items amp sub-assemblies With this
study the VAVE team had divided the main project into many sub-projects with respect
to subassemblies to have diversified results for subassemblies and parts This function
diagram threw up many questions to the team which enabled them to come up with a
number of new ideas
bull How the Product is sized What design parameters were employed for this product
bull Focus on high cost components and challenge by asking ldquowhy do we need this part and
what value does it provide to our customerrdquo
bull How else we can designmake it
bull Understand design change impact on subassembly or overall product
bull System level appraisal is desirable to consider different methods or concepts for
delivering the same or better value
bull Component level assessment is lookedfor to consider alternate materials processes and
more efficient designs
bull One of the guiding principles of lean design is to ldquoeliminate or standardizerdquo Can a part
be combined with others and thereby be eliminated If not can it be made common with
other parts in the product
without compromising FFF (Form Fit amp Function) This typically provides quick savings
bull Identify and capture all cost reduction opportunities
The team applied the concept of Pugh Matrix for system amp component level Rankings
were discussed with team collated and analyzed for choosing the optimum concepts
Next FMEA was conducted on the selected concepts to further fine tune the results
Failure modes with high Risk Priority Number (RPN) were identified Failure modes
were prioritized and communicated to the designers to address these risks Alternate
solutions and improvement were discussed and finalized 3D solid modeling was done to
visualize the product It also helped to simulate the active and passive conditions of the
product Components were standardized to reduce the part count Simulation and testing
against the CTQs helped to optimize the product for performances Design calculations
were performed to verify the design for gears springs snaps in the plastic members etc
Also the DFMA was conducted on various aspects of the design amp CTQs A detailed
Differential Cost Analysis was conducted with the customer and their suppliers The
result showed significant cost reduction of each part of the product It was observed that
the costs were reduced mainly due to alternate materials usage the process and by
eliminationreplacement of a part by integrating with the adjacent one
Costs of direct material were compared for the original and new design A significant
38 of savings in direct material cost was realized by this project The team also
achieved a reduction of 34 in the part count This has resulted in many intangible
benefits like savings in procurement costs Inspection costs Inventory cost
transportation reduced variation reduced assembly costs amp Time etc
6 Conclusion
QuEST lsquoValue Engineering teamrsquo achieved 38 of savings in direct material cost and
reduced part count by 34 in this project Having a Paint brush does not make one a
painter While we strive to implement the different VAVE tools we realize that the years
of experience in product design amp development is very essential to achieve the desired
objective VAVE tools and techniques if applied properly with trained amp experienced
resources will provide an extremely powerful suite to improve productivity lower cost
improve quality and also shorten the time-to-market

CONCLUSION
Value analysis is a technique with immense possibilities and systematically employed it
can achieve great economies and increased efficiency Although good results have been
obtained in several individual cases in some industries only a large scale and systematic
application of this technique in all industries and in defence production can result in
substantial economies on a national scale
This valuable technique if systematically employed promises rich dividends and
among other things enables greater use of indigenous raw materials and equipment by
import substitution It is therefore of special significance to a developing country like
India which has adopted a programme of rapid industrialization in the face of paucity of
foreign exchange and other handicaps
No Company can take seriously Total Quality Management without operating a
formalized system of Value Analysis No business that wishes to become lean will ever
succeed if product designs remain unchanged because no amount of continuous
improvement in the manufacturing process can release the costs of a poor design or a
design that has not changed for many years
However poor product reviews or an informal process that is restricted to only to a
review of the design by the design department will yield only limited success in
eliminating lsquoavoidable costsrsquo These efforts will miss the many opportunities to make
manufacturing and assembly easier quicker less complex and less costly Thus margins
will not be improved significantly because only a small part of the total process has been
managed correctly As such this type of superficial activity will not generate increased
profit and the revenue stream that will be needed to finance new products and new
investments in technology A properly managed and effective VA process will easily
repay the time invested by managers over the life of the product and a truly effective
process will yield significant competitive advantage for companies that exploit it For
businesses that supply other organizations the ability to design and redesign products
opens the possibility of true meaningful profitable and long-term partnership with a
customer Each progressive step that secures a greater design responsibility for the
supplier will in parallel make the supplier increasingly more important to the
competitive advantage of the customer organization and will increase the benefits to both
companies In an environment where budgets are often reduced the market determines
the selling price of a product and consumers demand a greater variety of products VA is
one technique that companies cannot afford to ignore because for every day that the
technique is not employed is money that will leave the business forever Money that
cannot be recovered once the product has been sold
The benefits of a formalized and effective VA process are therefore many and include
some key sources of competitive advantage for any business including
bull Speed of getting an effective design into the market without problems and through
error-free manufacturing and assembly processes
bull Reliability and durability of the product in the market which enhances the reputation
of the product and the company
bull Low overall cost which enhances product margin and also releases finances within the
business as well as allowing the ability to engage in price competition
bull Enhanced quality and compliance with minimal costs of warranty that allows a
company to differentiate its products based this perceived quality (of use and esteem)
bull Differentiation by creating product designs as platforms which facilitate lsquolast
minutersquo or late configuration of the product to meet customer orders regional preferences
or any other geographical constraint (such as product laws of a certain region)
bull Finally the VA process satisfies the primary goal of any business ndash to make a profit
and survive
As a process VA is very robust and offers tangible financial and people-based benefits
The process eliminates unnecessary weight it removes unnecessary costs and importantly
it allows people to understand products processes and continuous improvement Very
few modern management techniques allow this form of participation and involvement
and even fewer have such a profound impact on the bottom line of the businessrsquos trading
accounts For companies that do not employ this technique there is one very frightening
thought that for every product that the company makes one or two may be bought by
competitors and subjected to value analysis Therefore these competitors can easily
recover the ground lost to any lsquobreakthroughrsquo new product with half the effort and half
the expense of starting from the beginning These competitors can also take the new
product and lsquostreamlinersquo it to offer maximum value at minimum cost thereby creating a
new product without any real expense This is perhaps the most frightening though of all

CONCLUSION
Value analysis is a technique with immense possibilities and systematically employed it
can achieve great economies and increased efficiency Although good results have been
obtained in several individual cases in some industries only a large scale and systematic
application of this technique in all industries and in defence production can result in
substantial economies on a national scale
This valuable technique if systematically employed promises rich dividends and
among other things enables greater use of indigenous raw materials and equipment by
import substitution It is therefore of special significance to a developing country like
India which has adopted a programme of rapid industrialization in the face of paucity of
foreign exchange and other handicaps
No Company can take seriously Total Quality Management without operating a
formalized system of Value Analysis No business that wishes to become lean will ever
succeed if product designs remain unchanged because no amount of continuous
improvement in the manufacturing process can release the costs of a poor design or a
design that has not changed for many years
However poor product reviews or an informal process that is restricted to only to a
review of the design by the design department will yield only limited success in
eliminating lsquoavoidable costsrsquo These efforts will miss the many opportunities to make
manufacturing and assembly easier quicker less complex and less costly Thus margins
will not be improved significantly because only a small part of the total process has been
managed correctly As such this type of superficial activity will not generate increased
profit and the revenue stream that will be needed to finance new products and new
investments in technology A properly managed and effective VA process will easily
repay the time invested by managers over the life of the product and a truly effective
process will yield significant competitive advantage for companies that exploit it For
businesses that supply other organizations the ability to design and redesign products
opens the possibility of true meaningful profitable and long-term partnership with a
customer Each progressive step that secures a greater design responsibility for the
supplier will in parallel make the supplier increasingly more important to the
competitive advantage of the customer organization and will increase the benefits to both
companies In an environment where budgets are often reduced the market determines
the selling price of a product and consumers demand a greater variety of products VA is
one technique that companies cannot afford to ignore because for every day that the
technique is not employed is money that will leave the business forever Money that
cannot be recovered once the product has been sold
The benefits of a formalized and effective VA process are therefore many and include
some key sources of competitive advantage for any business including
bull Speed of getting an effective design into the market without problems and through
error-free manufacturing and assembly processes
bull Reliability and durability of the product in the market which enhances the reputation
of the product and the company
bull Low overall cost which enhances product margin and also releases finances within the
business as well as allowing the ability to engage in price competition
bull Enhanced quality and compliance with minimal costs of warranty that allows a
company to differentiate its products based this perceived quality (of use and esteem)
bull Differentiation by creating product designs as platforms which facilitate lsquolast
minutersquo or late configuration of the product to meet customer orders regional preferences
or any other geographical constraint (such as product laws of a certain region)
bull Finally the VA process satisfies the primary goal of any business ndash to make a profit
and survive
As a process VA is very robust and offers tangible financial and people-based benefits
The process eliminates unnecessary weight it removes unnecessary costs and importantly
it allows people to understand products processes and continuous improvement Very
few modern management techniques allow this form of participation and involvement
and even fewer have such a profound impact on the bottom line of the businessrsquos trading
accounts For companies that do not employ this technique there is one very frightening
thought that for every product that the company makes one or two may be bought by
competitors and subjected to value analysis Therefore these competitors can easily
recover the ground lost to any lsquobreakthroughrsquo new product with half the effort and half
the expense of starting from the beginning These competitors can also take the new
product and lsquostreamlinersquo it to offer maximum value at minimum cost thereby creating a
new product without any real expense This is perhaps the most frightening though of all

The value of a function can be increased by four methods
1 Decrease the cost while ensuring the same level of performance
2 Enhance the performance at the same cost
3 Decrease the cost and increase the performance
4 Increase both performance and cost ensuring that performance increases more than
the increment in the cost
ORGANISATION FOR VALUE ANALYSIS
Value analysis is a staff function like for instance Industrial Engineering and should be
organized as much It should be directly under a high-ranking officer from the Senior
Management of an undertaking This is necessary because Value Analysis concerns all
departments and the analyst must have access to them and to their records performance
costs etc Depending upon the size of the undertaking and its scale of operations there
can be a Central Value Analysis Cell to co-ordinate the work of individual analysts
attached to the design purchase production and engineering departments Where there is
only one Value Analyst he may be attached to the Industrial Engineering Department or
to the Purchase Department Value Analysis is essentially a team effort What particular
items to be taken up for value analysis and what action is to be taken is usually decided
by a small committee comprising representatives from the Design Production Purchase
and Accounts Departments Any other departmental representative can be coopted if and
when necessary It is the Purchase Manager (or Material Manager) who has to initiate
action convene meetings at regular intervals and see that substantial results are obtained
A large share of the initial phase of the Value Analysis work will be done by the

is initiated by the Purchase Manager
VALUE ENGINEERING
Value engineering is the term applied to value analysis done the design and prototype
stage of a product The potentials of saving are a more in case value analysis is done at
design stage Other advantages is that any changes at this stage are less costly than to
effect the same at a latter stage when the production is in full swing There are a few
limitations however on value engineering work At the design and proto-type stage the
time is rather short since a company wants to put a new product in the market before any
of its competitors can set in and value engineering will have a very short time to apply
their techniques Evaluation of the value at this stage becomes difficult in absence of any
customer reaction and opinion

ldquoCost Reduction of a product throughValue Analysis amp Value Engineeringrdquo
Introduction
The current business scenario is very demanding with a continuous demand from the
market forces to reduce the product price The pricing as demanded by the market forces
the businesses to reduce product development and manufacturing costs to remain
competitive Manufacturing costs of a product can be broadly categorized in the
following heads
bull Raw material
bull Labor
bull Process that is technology driven
Product engineers are constantly faced with the following challenges
bull Reduce production cost
bull Reduce the material cost
Value Analysis amp Value Engineering (VAVE) methods are very important and useful
in driving down the product cost which helps companies retain market share and sustain
their profitability
At QuEST we uncover those projects of our customer which have a good potential to
improve profits QuEST has a team of engineers who specialize in VAVE to achieve cost
reductions of products
A typical VAVE exercise could reduce the total cost of a product by 5-40 The typical
elements of a VAVE exercise are as follows
bull Information Understand the current state of the project and constraints requirements
bull Function Analysis Understand the project from a functional perspective what must
the project do rather than how the project is currently conceived The function describes
what something does and function analysis is the process where the team reviews the
projects functions to determine those that could be improved Function Analysis can be
enhanced through the use of a graphical mapping tool known as the Function Analysis
System Technique (FAST) FAST applies intuitive logic to test functions create a
common language for a team and test the validity of the functions in the project
bull Creative Generate a quantity of ideas related to other ways to perform the functions
bull Evaluation Reduce the quantity of ideas that have been identified to a short list of
ideas with the greatest potential to improve the project and meet the Value Engineering
study objective
bull Development Further analyze and develop the short list of ideas and develop those
with merit into value alternatives
bull Presentation Phase Implementation Present value alternatives to management team
and other project stakeholders or decision makers
5 Typical Flowchart
An example
The approach to a real life problem and the methodology followed by QuEST to reduce
the product cost is demonstrated through the following example
51 Background and Problem statement
One of the customers of QuEST is a leading manufacturer of industrial components for
control applications This unit is very popular in high end applications
The customer wanted to develop a unit that not only costs 25 less but whose
performance exceeds that of the existing product
52 Challenges
bull Redesign of parts considering minimum impact on existing tooling
bull Redesigned modules should enable field replacement
bull LogicSoftware compatibility with field units
bull Ease of assembly
bull Design must match existing housings and connectors
bull No modification of standardized parts in the product family
54 Value Engineering Study
QuEST team captured the detailed requirements of the project from the Voice of
Customer (VOC) during the kick off meeting It helped to identify areas where cost could
be reduced and which functions needed to be improved to provide competitive advantage
The requirements were listed and prioritized as primary and secondary These prioritized
ldquoNeeds and Wantsrdquo were ranked Quality Function Deployment (QFD) tool was used to
prioritize the ldquoHowrsquosrdquo that affected the ldquoNeeds and Wantsrdquo of the customer The
customer also actively participated in this exercise Vital few options were prioritized
from the trivial many Design requirement ranks were sorted in descending order and
those which addressed 70 of the requirements were selected Thus CTQs or
performance characteristics were identified and agreed upon with the customer The team
then carried out the lsquoABC analysisrsquo on the BOM Components with more than 80 of the
product cost were identified
CTQ (Critical to Quality)
Matches basic function and performance characteristics
One to one module replacement
Same Outer dimensions for the modules
LogicSoftware compatibility with field units
No modification in standardized parts in Product family
Design must match existing housings and connectors
Reduce the cost of direct material by 25 or more
Next the VAVE team laid down the Functions of each item of the product for Value
analysis
This enhanced the understanding of the product functionality This also helped to
understand the Form Fit amp Functions of each of the items amp sub-assemblies With this
study the VAVE team had divided the main project into many sub-projects with respect
to subassemblies to have diversified results for subassemblies and parts This function
diagram threw up many questions to the team which enabled them to come up with a
number of new ideas
bull How the Product is sized What design parameters were employed for this product
bull Focus on high cost components and challenge by asking ldquowhy do we need this part and
what value does it provide to our customerrdquo
bull How else we can designmake it
bull Understand design change impact on subassembly or overall product
bull System level appraisal is desirable to consider different methods or concepts for
delivering the same or better value
bull Component level assessment is lookedfor to consider alternate materials processes and
more efficient designs
bull One of the guiding principles of lean design is to ldquoeliminate or standardizerdquo Can a part
be combined with others and thereby be eliminated If not can it be made common with
other parts in the product
without compromising FFF (Form Fit amp Function) This typically provides quick savings
bull Identify and capture all cost reduction opportunities
The team applied the concept of Pugh Matrix for system amp component level Rankings
were discussed with team collated and analyzed for choosing the optimum concepts
Next FMEA was conducted on the selected concepts to further fine tune the results
Failure modes with high Risk Priority Number (RPN) were identified Failure modes
were prioritized and communicated to the designers to address these risks Alternate
solutions and improvement were discussed and finalized 3D solid modeling was done to
visualize the product It also helped to simulate the active and passive conditions of the
product Components were standardized to reduce the part count Simulation and testing
against the CTQs helped to optimize the product for performances Design calculations
were performed to verify the design for gears springs snaps in the plastic members etc
Also the DFMA was conducted on various aspects of the design amp CTQs A detailed
Differential Cost Analysis was conducted with the customer and their suppliers The
result showed significant cost reduction of each part of the product It was observed that
the costs were reduced mainly due to alternate materials usage the process and by
eliminationreplacement of a part by integrating with the adjacent one
Costs of direct material were compared for the original and new design A significant
38 of savings in direct material cost was realized by this project The team also
achieved a reduction of 34 in the part count This has resulted in many intangible
benefits like savings in procurement costs Inspection costs Inventory cost
transportation reduced variation reduced assembly costs amp Time etc
6 Conclusion
QuEST lsquoValue Engineering teamrsquo achieved 38 of savings in direct material cost and
reduced part count by 34 in this project Having a Paint brush does not make one a

CONCLUSION
Value analysis is a technique with immense possibilities and systematically employed it
can achieve great economies and increased efficiency Although good results have been
obtained in several individual cases in some industries only a large scale and systematic
application of this technique in all industries and in defence production can result in
substantial economies on a national scale
This valuable technique if systematically employed promises rich dividends and
among other things enables greater use of indigenous raw materials and equipment by
import substitution It is therefore of special significance to a developing country like
India which has adopted a programme of rapid industrialization in the face of paucity of
foreign exchange and other handicaps
No Company can take seriously Total Quality Management without operating a
formalized system of Value Analysis No business that wishes to become lean will ever
succeed if product designs remain unchanged because no amount of continuous
improvement in the manufacturing process can release the costs of a poor design or a
design that has not changed for many years
However poor product reviews or an informal process that is restricted to only to a
review of the design by the design department will yield only limited success in
eliminating lsquoavoidable costsrsquo These efforts will miss the many opportunities to make
manufacturing and assembly easier quicker less complex and less costly Thus margins
will not be improved significantly because only a small part of the total process has been
managed correctly As such this type of superficial activity will not generate increased
profit and the revenue stream that will be needed to finance new products and new
investments in technology A properly managed and effective VA process will easily
repay the time invested by managers over the life of the product and a truly effective
process will yield significant competitive advantage for companies that exploit it For
businesses that supply other organizations the ability to design and redesign products
opens the possibility of true meaningful profitable and long-term partnership with a
customer Each progressive step that secures a greater design responsibility for the
supplier will in parallel make the supplier increasingly more important to the
competitive advantage of the customer organization and will increase the benefits to both
companies In an environment where budgets are often reduced the market determines
the selling price of a product and consumers demand a greater variety of products VA is
one technique that companies cannot afford to ignore because for every day that the
technique is not employed is money that will leave the business forever Money that
cannot be recovered once the product has been sold
The benefits of a formalized and effective VA process are therefore many and include
some key sources of competitive advantage for any business including
bull Speed of getting an effective design into the market without problems and through
error-free manufacturing and assembly processes
bull Reliability and durability of the product in the market which enhances the reputation
of the product and the company
bull Low overall cost which enhances product margin and also releases finances within the
business as well as allowing the ability to engage in price competition
bull Enhanced quality and compliance with minimal costs of warranty that allows a
company to differentiate its products based this perceived quality (of use and esteem)
bull Differentiation by creating product designs as platforms which facilitate lsquolast
minutersquo or late configuration of the product to meet customer orders regional preferences
or any other geographical constraint (such as product laws of a certain region)
bull Finally the VA process satisfies the primary goal of any business ndash to make a profit
and survive
As a process VA is very robust and offers tangible financial and people-based benefits
The process eliminates unnecessary weight it removes unnecessary costs and importantly
it allows people to understand products processes and continuous improvement Very
few modern management techniques allow this form of participation and involvement
and even fewer have such a profound impact on the bottom line of the businessrsquos trading
accounts For companies that do not employ this technique there is one very frightening
thought that for every product that the company makes one or two may be bought by
competitors and subjected to value analysis Therefore these competitors can easily
recover the ground lost to any lsquobreakthroughrsquo new product with half the effort and half
the expense of starting from the beginning These competitors can also take the new
product and lsquostreamlinersquo it to offer maximum value at minimum cost thereby creating a
new product without any real expense This is perhaps the most frightening though of all

VALUE ANALYSIS JOB PLAN
Several versions of the VA Job Plan can be found in different literature Some give file
others six and yet many other seven phases It is the systematic approach which is more
important to achieve the desired objectives The phases of VA Job Plan are as follows
SELECTION amp ORIENTATION
ANALYSIS
RECORDING IDEAS
SPECULATION
INVESTIGATION
RECOMMENDATION
IMPLEMENTATION
1) SELECTION amp - to select those problems areas ORIENTATION where a potential for
net higher Savings is expected - use the common paretorsquos ABC analysis - general scope
restrictions and aims of the study is defined
2) ANALYSIS - to examine the data at a coordinated syndicate meeting - to appoint a
secretary to record the minutes - to apply the Tests for Value - to propose further actions
3) RECORDING IDEAS - the secretary writes clearly the minutes of the analysis
meeting
and circulates them to syndicate members - it includes the agenda for the next meeting
4) SPECULATION - to hold additional syndicate 64 meetings in order to discuss the
ideas analysed and any new information obtained - to speculate upon practical measures
for reducing costs and increasing value
5) INVESTIGATION - to investigate suggestions for reducing costs and to make them
practical and acceptable - to obtain definite prices and costs in order to estimate savings
accurately
6) RECOMMENDATION - recommended practical savings to management for
implementing - to present the recommendations as a comprehensive report - to appoint a
member to act as an implementation consultant
7) IMPLEMENTATION - to decide on future plans for the company for which the
authority of the management is needed - to implement the recommendations acceptable to
the management
The value of a function can be increased by four methods
1 Decrease the cost while ensuring the same level of performance
2 Enhance the performance at the same cost
3 Decrease the cost and increase the performance
4 Increase both performance and cost ensuring that performance increases more than
the increment in the cost
ORGANISATION FOR VALUE ANALYSIS
Value analysis is a staff function like for instance Industrial Engineering and should be
organized as much It should be directly under a high-ranking officer from the Senior
Management of an undertaking This is necessary because Value Analysis concerns all
departments and the analyst must have access to them and to their records performance
costs etc Depending upon the size of the undertaking and its scale of operations there
can be a Central Value Analysis Cell to co-ordinate the work of individual analysts
attached to the design purchase production and engineering departments Where there is
only one Value Analyst he may be attached to the Industrial Engineering Department or
to the Purchase Department Value Analysis is essentially a team effort What particular
items to be taken up for value analysis and what action is to be taken is usually decided
by a small committee comprising representatives from the Design Production Purchase
and Accounts Departments Any other departmental representative can be coopted if and
when necessary It is the Purchase Manager (or Material Manager) who has to initiate
action convene meetings at regular intervals and see that substantial results are obtained
A large share of the initial phase of the Value Analysis work will be done by the
Purchase Manager or by other departments at his instance It is his responsibility to seek
the maximum value when a product requirement comes upto the point of purchase It is
his duty to challenge wasteful and avoidable costs inherent in the items he is asked to
buy It is therefore inevitable that a large part of whatever Value Analysis work is done
is initiated by the Purchase Manager
VALUE ENGINEERING
Value engineering is the term applied to value analysis done the design and prototype
stage of a product The potentials of saving are a more in case value analysis is done at
design stage Other advantages is that any changes at this stage are less costly than to
effect the same at a latter stage when the production is in full swing There are a few
limitations however on value engineering work At the design and proto-type stage the
time is rather short since a company wants to put a new product in the market before any
of its competitors can set in and value engineering will have a very short time to apply
their techniques Evaluation of the value at this stage becomes difficult in absence of any
customer reaction and opinion
WHEN VALUE ANALYSIS
A product goes through 3 stages (1) Developmental (2) Growth and (3) Maturity before
being out of date Consider now the design efforts put on a product At developmental
stages the design effort is the maximum At the growth stage the effort is much less and is
mainly modifications and changes At maturity stage hardly any design attention is
needed The value of the product slowly increases in development and growth stages as
more features are added and desired changes and modifications are effected At maturity
stage the value increases to peak and then slowly starts reduction because of competition
change of customer tastes and other factors till the product falls out and becomes out of
date It is this stage where value analysis can still enhance the value by cost reduction
and lengthen the Maturity period of a product Thus when the design effort is diverted to
other products it is the time for value analysis to be undertaken The success of value
analysis for one product of course be made use of in the design of other products by
development wing
CASE STUDY
ldquoCost Reduction of a product throughValue Analysis amp Value Engineeringrdquo
Introduction
The current business scenario is very demanding with a continuous demand from the
market forces to reduce the product price The pricing as demanded by the market forces
the businesses to reduce product development and manufacturing costs to remain
competitive Manufacturing costs of a product can be broadly categorized in the
following heads
bull Raw material
bull Labor
bull Process that is technology driven
Product engineers are constantly faced with the following challenges
bull Reduce production cost
bull Reduce the material cost
Value Analysis amp Value Engineering (VAVE) methods are very important and useful
in driving down the product cost which helps companies retain market share and sustain
their profitability
At QuEST we uncover those projects of our customer which have a good potential to
improve profits QuEST has a team of engineers who specialize in VAVE to achieve cost
reductions of products
A typical VAVE exercise could reduce the total cost of a product by 5-40 The typical
elements of a VAVE exercise are as follows
bull Information Understand the current state of the project and constraints requirements
bull Function Analysis Understand the project from a functional perspective what must
the project do rather than how the project is currently conceived The function describes
what something does and function analysis is the process where the team reviews the
projects functions to determine those that could be improved Function Analysis can be
enhanced through the use of a graphical mapping tool known as the Function Analysis
System Technique (FAST) FAST applies intuitive logic to test functions create a
common language for a team and test the validity of the functions in the project
bull Creative Generate a quantity of ideas related to other ways to perform the functions
bull Evaluation Reduce the quantity of ideas that have been identified to a short list of
ideas with the greatest potential to improve the project and meet the Value Engineering
study objective
bull Development Further analyze and develop the short list of ideas and develop those
with merit into value alternatives
bull Presentation Phase Implementation Present value alternatives to management team
and other project stakeholders or decision makers
5 Typical Flowchart
An example
The approach to a real life problem and the methodology followed by QuEST to reduce
the product cost is demonstrated through the following example
51 Background and Problem statement
One of the customers of QuEST is a leading manufacturer of industrial components for
control applications This unit is very popular in high end applications
The customer wanted to develop a unit that not only costs 25 less but whose
performance exceeds that of the existing product
52 Challenges
bull Redesign of parts considering minimum impact on existing tooling
bull Redesigned modules should enable field replacement
bull LogicSoftware compatibility with field units

CONCLUSION
Value analysis is a technique with immense possibilities and systematically employed it
can achieve great economies and increased efficiency Although good results have been
obtained in several individual cases in some industries only a large scale and systematic
application of this technique in all industries and in defence production can result in
substantial economies on a national scale
This valuable technique if systematically employed promises rich dividends and
among other things enables greater use of indigenous raw materials and equipment by
import substitution It is therefore of special significance to a developing country like
India which has adopted a programme of rapid industrialization in the face of paucity of
foreign exchange and other handicaps
No Company can take seriously Total Quality Management without operating a
formalized system of Value Analysis No business that wishes to become lean will ever
succeed if product designs remain unchanged because no amount of continuous
improvement in the manufacturing process can release the costs of a poor design or a
design that has not changed for many years
However poor product reviews or an informal process that is restricted to only to a
review of the design by the design department will yield only limited success in
eliminating lsquoavoidable costsrsquo These efforts will miss the many opportunities to make
manufacturing and assembly easier quicker less complex and less costly Thus margins
will not be improved significantly because only a small part of the total process has been
managed correctly As such this type of superficial activity will not generate increased
profit and the revenue stream that will be needed to finance new products and new
investments in technology A properly managed and effective VA process will easily
repay the time invested by managers over the life of the product and a truly effective
process will yield significant competitive advantage for companies that exploit it For
businesses that supply other organizations the ability to design and redesign products
opens the possibility of true meaningful profitable and long-term partnership with a
customer Each progressive step that secures a greater design responsibility for the
supplier will in parallel make the supplier increasingly more important to the
competitive advantage of the customer organization and will increase the benefits to both
companies In an environment where budgets are often reduced the market determines
the selling price of a product and consumers demand a greater variety of products VA is
one technique that companies cannot afford to ignore because for every day that the
technique is not employed is money that will leave the business forever Money that
cannot be recovered once the product has been sold
The benefits of a formalized and effective VA process are therefore many and include
some key sources of competitive advantage for any business including
bull Speed of getting an effective design into the market without problems and through
error-free manufacturing and assembly processes
bull Reliability and durability of the product in the market which enhances the reputation
of the product and the company
bull Low overall cost which enhances product margin and also releases finances within the
business as well as allowing the ability to engage in price competition
bull Enhanced quality and compliance with minimal costs of warranty that allows a
company to differentiate its products based this perceived quality (of use and esteem)
bull Differentiation by creating product designs as platforms which facilitate lsquolast
minutersquo or late configuration of the product to meet customer orders regional preferences
or any other geographical constraint (such as product laws of a certain region)
bull Finally the VA process satisfies the primary goal of any business ndash to make a profit
and survive
As a process VA is very robust and offers tangible financial and people-based benefits
The process eliminates unnecessary weight it removes unnecessary costs and importantly
it allows people to understand products processes and continuous improvement Very
few modern management techniques allow this form of participation and involvement
and even fewer have such a profound impact on the bottom line of the businessrsquos trading
accounts For companies that do not employ this technique there is one very frightening
thought that for every product that the company makes one or two may be bought by
competitors and subjected to value analysis Therefore these competitors can easily
recover the ground lost to any lsquobreakthroughrsquo new product with half the effort and half
the expense of starting from the beginning These competitors can also take the new
product and lsquostreamlinersquo it to offer maximum value at minimum cost thereby creating a
new product without any real expense This is perhaps the most frightening though of all

when necessary It is the Purchase Manager (or Material Manager) who has to initiate
action convene meetings at regular intervals and see that substantial results are obtained
A large share of the initial phase of the Value Analysis work will be done by the
Purchase Manager or by other departments at his instance It is his responsibility to seek
the maximum value when a product requirement comes upto the point of purchase It is
his duty to challenge wasteful and avoidable costs inherent in the items he is asked to
buy It is therefore inevitable that a large part of whatever Value Analysis work is done
is initiated by the Purchase Manager
VALUE ENGINEERING
Value engineering is the term applied to value analysis done the design and prototype
stage of a product The potentials of saving are a more in case value analysis is done at
design stage Other advantages is that any changes at this stage are less costly than to
effect the same at a latter stage when the production is in full swing There are a few
limitations however on value engineering work At the design and proto-type stage the
time is rather short since a company wants to put a new product in the market before any
of its competitors can set in and value engineering will have a very short time to apply
their techniques Evaluation of the value at this stage becomes difficult in absence of any
customer reaction and opinion
WHEN VALUE ANALYSIS
A product goes through 3 stages (1) Developmental (2) Growth and (3) Maturity before
being out of date Consider now the design efforts put on a product At developmental
stages the design effort is the maximum At the growth stage the effort is much less and is
mainly modifications and changes At maturity stage hardly any design attention is
needed The value of the product slowly increases in development and growth stages as
more features are added and desired changes and modifications are effected At maturity
stage the value increases to peak and then slowly starts reduction because of competition
change of customer tastes and other factors till the product falls out and becomes out of
date It is this stage where value analysis can still enhance the value by cost reduction
and lengthen the Maturity period of a product Thus when the design effort is diverted to
other products it is the time for value analysis to be undertaken The success of value
analysis for one product of course be made use of in the design of other products by
development wing
CASE STUDY
ldquoCost Reduction of a product throughValue Analysis amp Value Engineeringrdquo
Introduction
The current business scenario is very demanding with a continuous demand from the
market forces to reduce the product price The pricing as demanded by the market forces
the businesses to reduce product development and manufacturing costs to remain
competitive Manufacturing costs of a product can be broadly categorized in the
following heads
bull Raw material
bull Labor
bull Process that is technology driven
Product engineers are constantly faced with the following challenges
bull Reduce production cost
bull Reduce the material cost
Value Analysis amp Value Engineering (VAVE) methods are very important and useful
in driving down the product cost which helps companies retain market share and sustain
their profitability
At QuEST we uncover those projects of our customer which have a good potential to
improve profits QuEST has a team of engineers who specialize in VAVE to achieve cost
reductions of products
A typical VAVE exercise could reduce the total cost of a product by 5-40 The typical
elements of a VAVE exercise are as follows
bull Information Understand the current state of the project and constraints requirements
bull Function Analysis Understand the project from a functional perspective what must
the project do rather than how the project is currently conceived The function describes
what something does and function analysis is the process where the team reviews the
projects functions to determine those that could be improved Function Analysis can be
enhanced through the use of a graphical mapping tool known as the Function Analysis
System Technique (FAST) FAST applies intuitive logic to test functions create a
common language for a team and test the validity of the functions in the project
bull Creative Generate a quantity of ideas related to other ways to perform the functions
bull Evaluation Reduce the quantity of ideas that have been identified to a short list of
ideas with the greatest potential to improve the project and meet the Value Engineering
study objective
bull Development Further analyze and develop the short list of ideas and develop those
with merit into value alternatives
bull Presentation Phase Implementation Present value alternatives to management team
and other project stakeholders or decision makers
5 Typical Flowchart
An example
The approach to a real life problem and the methodology followed by QuEST to reduce
the product cost is demonstrated through the following example
51 Background and Problem statement
One of the customers of QuEST is a leading manufacturer of industrial components for
control applications This unit is very popular in high end applications
The customer wanted to develop a unit that not only costs 25 less but whose
performance exceeds that of the existing product
52 Challenges
bull Redesign of parts considering minimum impact on existing tooling
bull Redesigned modules should enable field replacement
bull LogicSoftware compatibility with field units
bull Ease of assembly
bull Design must match existing housings and connectors
bull No modification of standardized parts in the product family
54 Value Engineering Study
QuEST team captured the detailed requirements of the project from the Voice of
Customer (VOC) during the kick off meeting It helped to identify areas where cost could
be reduced and which functions needed to be improved to provide competitive advantage
The requirements were listed and prioritized as primary and secondary These prioritized
ldquoNeeds and Wantsrdquo were ranked Quality Function Deployment (QFD) tool was used to
prioritize the ldquoHowrsquosrdquo that affected the ldquoNeeds and Wantsrdquo of the customer The
customer also actively participated in this exercise Vital few options were prioritized
from the trivial many Design requirement ranks were sorted in descending order and
those which addressed 70 of the requirements were selected Thus CTQs or
performance characteristics were identified and agreed upon with the customer The team
then carried out the lsquoABC analysisrsquo on the BOM Components with more than 80 of the
product cost were identified
CTQ (Critical to Quality)
Matches basic function and performance characteristics
One to one module replacement
Same Outer dimensions for the modules

Reduce the cost of direct material by 25 or more
Next the VAVE team laid down the Functions of each item of the product for Value
analysis
This enhanced the understanding of the product functionality This also helped to
understand the Form Fit amp Functions of each of the items amp sub-assemblies With this
study the VAVE team had divided the main project into many sub-projects with respect
to subassemblies to have diversified results for subassemblies and parts This function
diagram threw up many questions to the team which enabled them to come up with a
number of new ideas
bull How the Product is sized What design parameters were employed for this product
bull Focus on high cost components and challenge by asking ldquowhy do we need this part and
what value does it provide to our customerrdquo
bull How else we can designmake it
bull Understand design change impact on subassembly or overall product
bull System level appraisal is desirable to consider different methods or concepts for
delivering the same or better value
bull Component level assessment is lookedfor to consider alternate materials processes and
more efficient designs
bull One of the guiding principles of lean design is to ldquoeliminate or standardizerdquo Can a part
be combined with others and thereby be eliminated If not can it be made common with
other parts in the product
without compromising FFF (Form Fit amp Function) This typically provides quick savings
bull Identify and capture all cost reduction opportunities
The team applied the concept of Pugh Matrix for system amp component level Rankings
were discussed with team collated and analyzed for choosing the optimum concepts
Next FMEA was conducted on the selected concepts to further fine tune the results
Failure modes with high Risk Priority Number (RPN) were identified Failure modes

QuEST team captured the detailed requirements of the project from the Voice of
Customer (VOC) during the kick off meeting It helped to identify areas where cost could
be reduced and which functions needed to be improved to provide competitive advantage
The requirements were listed and prioritized as primary and secondary These prioritized
ldquoNeeds and Wantsrdquo were ranked Quality Function Deployment (QFD) tool was used to
prioritize the ldquoHowrsquosrdquo that affected the ldquoNeeds and Wantsrdquo of the customer The
customer also actively participated in this exercise Vital few options were prioritized
from the trivial many Design requirement ranks were sorted in descending order and
those which addressed 70 of the requirements were selected Thus CTQs or
performance characteristics were identified and agreed upon with the customer The team
then carried out the lsquoABC analysisrsquo on the BOM Components with more than 80 of the
product cost were identified

CONCLUSION
Value analysis is a technique with immense possibilities and systematically employed it
can achieve great economies and increased efficiency Although good results have been
obtained in several individual cases in some industries only a large scale and systematic
application of this technique in all industries and in defence production can result in
substantial economies on a national scale
This valuable technique if systematically employed promises rich dividends and
among other things enables greater use of indigenous raw materials and equipment by
import substitution It is therefore of special significance to a developing country like
India which has adopted a programme of rapid industrialization in the face of paucity of
foreign exchange and other handicaps
No Company can take seriously Total Quality Management without operating a
formalized system of Value Analysis No business that wishes to become lean will ever
succeed if product designs remain unchanged because no amount of continuous
improvement in the manufacturing process can release the costs of a poor design or a
design that has not changed for many years
However poor product reviews or an informal process that is restricted to only to a
review of the design by the design department will yield only limited success in
eliminating lsquoavoidable costsrsquo These efforts will miss the many opportunities to make
manufacturing and assembly easier quicker less complex and less costly Thus margins
will not be improved significantly because only a small part of the total process has been
managed correctly As such this type of superficial activity will not generate increased
profit and the revenue stream that will be needed to finance new products and new
investments in technology A properly managed and effective VA process will easily
repay the time invested by managers over the life of the product and a truly effective
process will yield significant competitive advantage for companies that exploit it For
businesses that supply other organizations the ability to design and redesign products
opens the possibility of true meaningful profitable and long-term partnership with a
customer Each progressive step that secures a greater design responsibility for the
supplier will in parallel make the supplier increasingly more important to the
competitive advantage of the customer organization and will increase the benefits to both
companies In an environment where budgets are often reduced the market determines
the selling price of a product and consumers demand a greater variety of products VA is
one technique that companies cannot afford to ignore because for every day that the
technique is not employed is money that will leave the business forever Money that
cannot be recovered once the product has been sold
The benefits of a formalized and effective VA process are therefore many and include
some key sources of competitive advantage for any business including
bull Speed of getting an effective design into the market without problems and through
error-free manufacturing and assembly processes
bull Reliability and durability of the product in the market which enhances the reputation
of the product and the company
bull Low overall cost which enhances product margin and also releases finances within the
business as well as allowing the ability to engage in price competition
bull Enhanced quality and compliance with minimal costs of warranty that allows a
company to differentiate its products based this perceived quality (of use and esteem)
bull Differentiation by creating product designs as platforms which facilitate lsquolast
minutersquo or late configuration of the product to meet customer orders regional preferences
or any other geographical constraint (such as product laws of a certain region)
bull Finally the VA process satisfies the primary goal of any business ndash to make a profit
and survive
As a process VA is very robust and offers tangible financial and people-based benefits
The process eliminates unnecessary weight it removes unnecessary costs and importantly
it allows people to understand products processes and continuous improvement Very
few modern management techniques allow this form of participation and involvement
and even fewer have such a profound impact on the bottom line of the businessrsquos trading
accounts For companies that do not employ this technique there is one very frightening
thought that for every product that the company makes one or two may be bought by
competitors and subjected to value analysis Therefore these competitors can easily
recover the ground lost to any lsquobreakthroughrsquo new product with half the effort and half
the expense of starting from the beginning These competitors can also take the new
product and lsquostreamlinersquo it to offer maximum value at minimum cost thereby creating a
new product without any real expense This is perhaps the most frightening though of all

CONCLUSION
Value analysis is a technique with immense possibilities and systematically employed it
can achieve great economies and increased efficiency Although good results have been
obtained in several individual cases in some industries only a large scale and systematic
application of this technique in all industries and in defence production can result in
substantial economies on a national scale
This valuable technique if systematically employed promises rich dividends and
among other things enables greater use of indigenous raw materials and equipment by
import substitution It is therefore of special significance to a developing country like
India which has adopted a programme of rapid industrialization in the face of paucity of
foreign exchange and other handicaps
No Company can take seriously Total Quality Management without operating a
formalized system of Value Analysis No business that wishes to become lean will ever
succeed if product designs remain unchanged because no amount of continuous
improvement in the manufacturing process can release the costs of a poor design or a
design that has not changed for many years
However poor product reviews or an informal process that is restricted to only to a
review of the design by the design department will yield only limited success in
eliminating lsquoavoidable costsrsquo These efforts will miss the many opportunities to make
manufacturing and assembly easier quicker less complex and less costly Thus margins
will not be improved significantly because only a small part of the total process has been
managed correctly As such this type of superficial activity will not generate increased
profit and the revenue stream that will be needed to finance new products and new
investments in technology A properly managed and effective VA process will easily
repay the time invested by managers over the life of the product and a truly effective
process will yield significant competitive advantage for companies that exploit it For
businesses that supply other organizations the ability to design and redesign products
opens the possibility of true meaningful profitable and long-term partnership with a
customer Each progressive step that secures a greater design responsibility for the
supplier will in parallel make the supplier increasingly more important to the
competitive advantage of the customer organization and will increase the benefits to both
companies In an environment where budgets are often reduced the market determines
the selling price of a product and consumers demand a greater variety of products VA is
one technique that companies cannot afford to ignore because for every day that the
technique is not employed is money that will leave the business forever Money that
cannot be recovered once the product has been sold
The benefits of a formalized and effective VA process are therefore many and include
some key sources of competitive advantage for any business including
bull Speed of getting an effective design into the market without problems and through
error-free manufacturing and assembly processes
bull Reliability and durability of the product in the market which enhances the reputation
of the product and the company
bull Low overall cost which enhances product margin and also releases finances within the
business as well as allowing the ability to engage in price competition
bull Enhanced quality and compliance with minimal costs of warranty that allows a
company to differentiate its products based this perceived quality (of use and esteem)
bull Differentiation by creating product designs as platforms which facilitate lsquolast
minutersquo or late configuration of the product to meet customer orders regional preferences
or any other geographical constraint (such as product laws of a certain region)
bull Finally the VA process satisfies the primary goal of any business ndash to make a profit
and survive
As a process VA is very robust and offers tangible financial and people-based benefits
The process eliminates unnecessary weight it removes unnecessary costs and importantly
it allows people to understand products processes and continuous improvement Very
few modern management techniques allow this form of participation and involvement
and even fewer have such a profound impact on the bottom line of the businessrsquos trading
accounts For companies that do not employ this technique there is one very frightening
thought that for every product that the company makes one or two may be bought by
competitors and subjected to value analysis Therefore these competitors can easily
recover the ground lost to any lsquobreakthroughrsquo new product with half the effort and half
the expense of starting from the beginning These competitors can also take the new
product and lsquostreamlinersquo it to offer maximum value at minimum cost thereby creating a
new product without any real expense This is perhaps the most frightening though of all

Reduce the cost of direct material by 25 or more
Next the VAVE team laid down the Functions of each item of the product for Value
analysis
This enhanced the understanding of the product functionality This also helped to
understand the Form Fit amp Functions of each of the items amp sub-assemblies With this
study the VAVE team had divided the main project into many sub-projects with respect
to subassemblies to have diversified results for subassemblies and parts This function
diagram threw up many questions to the team which enabled them to come up with a
number of new ideas
bull How the Product is sized What design parameters were employed for this product
bull Focus on high cost components and challenge by asking ldquowhy do we need this part and
what value does it provide to our customerrdquo
bull How else we can designmake it
bull Understand design change impact on subassembly or overall product
bull System level appraisal is desirable to consider different methods or concepts for
delivering the same or better value
bull Component level assessment is lookedfor to consider alternate materials processes and
more efficient designs
bull One of the guiding principles of lean design is to ldquoeliminate or standardizerdquo Can a part
be combined with others and thereby be eliminated If not can it be made common with
other parts in the product
without compromising FFF (Form Fit amp Function) This typically provides quick savings
bull Identify and capture all cost reduction opportunities
The team applied the concept of Pugh Matrix for system amp component level Rankings
were discussed with team collated and analyzed for choosing the optimum concepts
Next FMEA was conducted on the selected concepts to further fine tune the results
Failure modes with high Risk Priority Number (RPN) were identified Failure modes
were prioritized and communicated to the designers to address these risks Alternate
solutions and improvement were discussed and finalized 3D solid modeling was done to
visualize the product It also helped to simulate the active and passive conditions of the
product Components were standardized to reduce the part count Simulation and testing
against the CTQs helped to optimize the product for performances Design calculations
were performed to verify the design for gears springs snaps in the plastic members etc
Also the DFMA was conducted on various aspects of the design amp CTQs A detailed
Differential Cost Analysis was conducted with the customer and their suppliers The
result showed significant cost reduction of each part of the product It was observed that
the costs were reduced mainly due to alternate materials usage the process and by
eliminationreplacement of a part by integrating with the adjacent one
Costs of direct material were compared for the original and new design A significant
38 of savings in direct material cost was realized by this project The team also
achieved a reduction of 34 in the part count This has resulted in many intangible
benefits like savings in procurement costs Inspection costs Inventory cost
transportation reduced variation reduced assembly costs amp Time etc
