Introduction
Supply Chain Management (SCM) can be best described as the natural
extension of the downsizing (right-sizing) and re-engineering performed by
the organization(s) in the past. Downsizing and re-engineering transformed
the enterprises into lean and mean competitive units, by cost cutting and
process simplifications. These operations (of downsizing and re-engineering)
involved the optimization (in terms of the number of persons involved, the
time taken, the complexity of the work etc.) of business units (functional
and/or administrative domains) over which the organizations had full control.
These strategies did lead to increased productivity and profitability of the
organizations but as the benefits of these leveled off, it was realized that the
approach to the way organizations work needed to be changed. The above
changes were a by-product of the isolationist (closed system) world picture
of the enterprises involved in the full value chain; with organizations (the
system) trying to survive in an hostile environment; assuming that all other
participants in the value chain were adversaries with whom the organization
must compete, even though the operations performed by the separate
organizations may be supplementary in nature rather than complementary.
The realization that this world picture was an impediment to the growth of
organizations prompted the enterprises to start seeking strategic alliances
with other organizations. The formation of these alliances required a basis (a
common ground) which would be acceptable to each and every partner in thealliance. This common basis is/was supplied by the participation of the
organizations in the value chain (the demand-supply chain). The participants
in the chain, suppliers, sub-contract suppliers, in house product processes,
transportation, distribution, warehouses, and the end customer, generally,
-

perform mutually exclusive tasks and thus do not compete directly with each
other.
Issues in SCM
A supply chain encompasses all the activities, functions and facilities
involved in producing and delivering a product and/or service, from suppliers
(and their suppliers) to the customers. The supply chain management (SCM)
paradigm is geared towards optimizing each component of what used to be
called (Production and) Operations management (production, warehousing,
inventory, transportation and distribution etc.) and the inter-links between
these components synergistically. In the 70s and the 80s, various models for
production and operations control and management were developed: Just-In-
Time (JIT) Inventory management model, Vendor Managed Inventory (VMI)
model, Zero Inventory (ZI) model, Total Quality Management (TQM) etc.
These models focused on the various components of the supply chain in
isolation, this implies that these models were oriented towards the
optimization of a sub-part of the system whereas the SCM paradigm aims at
the optimization of the full chain. This leads to trade-offs among the different
components of the supply chain. For example, JIT would require a factory to
keep inventories low and produce and distribute products in a timely manner,
however JIT ignores many other aspects which cannot be seen independently,
e.g. if the availability of the input materials is uncertain and irregular, the
factory may need to insure smooth and continuous production. Similarly,
regional stocking may permit reductions in transportation costs through
increased shipment consolidation, as well as expanded sales through better
delivery performance. These improvements may be accomplished with only
moderate increases in inventory and warehousing cost(s). However, in an
-

environment where different functional units manage the various logistics
activities independently, an organization is less likely to properly analyze such
important trade-offs.
Fig. -1 : Interdependence of supply chain with other functional domains
in an enterprise.
Moreover, these models also ignore the interdependency of production
and operations functions with other domains within an organization, such as
marketing and finance. Marketing decisions have serious impact on logisticsfunction and vice-versa. For example, a marketing promotion campaign
should be coordinated with production planning, since a higher demand may
be expected. On the other hand, when raw materials are cheap, or when the
factory temporarily has an over-capacity, the marketing department may
decide to cut prices and/or start other promotion campaigns during these
periods to increase demands. Also, financial decisions are driven by
production and logistics decisions. Production of new products requires the
investment in raw materials and consumes other change-over costs. Financial
managers have to be aware of the increased demand for capital to finance the
production plan. Likewise, the delivery of finished products generates
-
7/31/2019 Or-Project Supply Chain
5/33
financial income, so the forecast demand can be used to calculate/forecast the
accounts payable and receivable in the future. The above description means
that production, finance and marketing decisions cannot be made
independently (fig.1). All these decisions are driven by the activities in the
supply chain of a manufacturing company. Fig.-1 shows a simple
representation of the interdependence of the supply chain and the other
functional domains in the organization. The links between the (other)
functional domains - marketing, sales, human resources etc. - are not shown.
The linkage between the supply chain components and the other functional
domains relies heavily on information sharing to have an effective impact.
One other major factor in the current scenario is the globalization of the
supply chain. With the fall of the East-European socialist bloc and the opening
of the Asian market, the trade barriers began falling in the 1980s and the 90s.
This lead to organizations having a supply chain that criss-crossed the globe.
The proliferation of trade agreements - EC, ASEAN, NAFTA, APEC, etc. - has
changed the global market. SCM now has become not only a problem oflogistics but also demands that supply chain management must look into the
ramifications of these agreements on the cost of transportation (including
tariffs or duties) of products within a trade zone and outside it[1].
Furthermore, organizations now acknowledge that efficient consumer
response (ECR) can lead to competitive edge. SCM is tantamount to
coordinating all the operations of an organization with the operations of the
suppliers and customers. Effective SCM strategies are essential for successful
implementation of ECR programmers. Thus, a production planning and
control model that focuses on all the aspects of the operations and
distribution activities and links with other functional domains such as finance
-

and marketing is needed. The supply chain management model should also
perform the task of managing and coordinating activities upstream and
downstream in the supply chain. Of course, such a model in its entirety
becomes very complex and cannot be used without a sufficient computational
infrastructure.
Supply-Demand Nexus
To have an effective supply chain management framework;
organizations must have a clear understanding of the supply - demand nexus
and its implications for strategy and implementation. There is an
interdependent relationship between supply and demand; organizations need
to understand customer demand so that they can manage it, create future
demand and, of course, meet the level of desired customer satisfaction.
Demand defines the supply chain target, while supply side capabilities
support, shape and sustain demand.
When one considers how tangentially marketing and operations area of
an organization typically interact (in practice), it becomes obvious that
putting together the supply-demand can only occur in the context of overall
perspective. The wide gap between the supply and demand sides of an
organization can only be bridged by a comprehensive umbrella strategy. This
can be done by developing a holistic strategic framework that leverages the
generation and understanding of demand effectiveness with supply efficiency.
Such a framework provides a strategic anchor to prevent the supply and
demand components of a business from drifting apart.
The basis of such a holistic strategy framework is the integrated supply
and demand model (Fig.-2). The model is designed around two key principles.
-
7/31/2019 Or-Project Supply Chain
7/33
First, in the present scenario where vertically integrated supply chains (VISC)
are a rarity, if not non-existent; organizations must bring a multi-enterprise
view to their supply chains. They must be capable of working co-operatively
with other organizations in the chain rather than seeking to outdo them.
Secondly, they must recognize the distinct supply and demand processes that
must be integrated in order to gain the greatest value.
Fig. -2 : The Integrated Demand-Supply Model
Thus involving three key elements:
The core process of the supply and demand chains viewed from a broadcross-enterprise vantage point rather than as discrete function. To gain the
maximum benefits, organizations need to identify the core processes
across the demand and supply chain, as well as exploring the impact of
each of these processes on the different functions.

Fig. -3 : Integrating processes in the supply and demand chains
The integrating processes that create the links between the supply anddemand chains (fig - 3). This implies that the planning processes (which
involves development of channel strategies, planning of manufacturing,
inventory, distribution and transportation, demand planning and
forecasting; and marketing and promotional planning) and service
processes (which includes functions such as credit, order management,
load planning, billing and collection, etc.) must be integrated. This
integration must be done across the boundaries of the enterprises. If each
participating organization in the chain formulates its own plans on the
basis of its own private information, then there is no way to integrate the
supply and demand chain processes that they share.
-

The supporting information technology (IT) infrastructure that makes suchintegration possible. While information technology is needed to handle
routine transactions in an efficient manner, it can also play the a critical
role in facilitating the timely sharing of planning, production and
purchasing information; capturing and analyzing production, distribution
and sales data at new levels of detail and complexity. Information
technology provides an integrating tools that makes it possible to convert
data into meaningful pictures of business processes, markets and
consumers that are needed to feed company strategies in order to develop
competitive advantage.
On the administrative side, such elements as flow path economics, which
help organizations understand the real drivers of costs, and new performance
and measurement standards that align functions in accordance with total
process goals that are critical to achieving integration.

SCM Framework
A framework to understand the various issues involved in SCM is provided
by the pyramid structure for the SCM paradigm The pyramid allows issues to
be analyzed on four levels:
Strategic: On the strategic, level it is important to know how SCM cancontribute to the enterprises basic value proposition to the customers.
Important questions that are addressed at this level include: What are the
basic and distinctive service needs of the customers? What can SCM do to
meet these needs? Can the SCM capabilities be used to provide unique
services to the customers? Etc.
Structural: After the strategic issues are dealt with, the next levelquestion(s) that should be asked are: Should the organization market
directly or should it use distributors or other intermediaries to reach the
customers? What should the SCM network look like? What products should
be sourced from which manufacturing locations? How many warehouses
should the company have and where should they be located? What is the
mission of each facility (full stocking, fast moving items only, cross-docking
etc.)? etc.
Functional: This is the level where operational details are decided upon.Functional excellence requires that the optimal operating practices for
transportation management, warehouse operations, and materials
management (which includes forecasting, inventory management,
production scheduling, and purchasing) are designed. These strategies
should keep in view the trade-offs that may need to be made for the overall
efficiency of the system. Achieving functional excellence also entails
-
7/31/2019 Or-Project Supply Chain
11/33
development of a process-oriented perspective on replenishment and
order fulfillment so that all activities involved in these functions can be
well integrated.
Implementation: Without successful implementation, the development ofSCM strategies and plans is meaningless. Of particular importance are the
organizational and information systems issues. Organizational issues
centers on the overall structure, individual roles and responsibilities, and
measurement systems needed to build an integrated operation.
Information systems are enablers for supply chain management
operations and therefore must be carefully designed to support the SCM
strategy. Supply chain managers must consider their information needs
relative to decision support tools, application softwares, data capture, and
the systems overall structure.
It is important to note that the decisions made within the SCM strategy
pyramid are interdependent. That is, it must be understood what capabilities
and limitations affect the functional and implementation decisions and
consider those factors while developing a supply chain management strategy
and structure.
The SCM models used in practice lie in a continuum between two extreme
models: on one end of the spectrum lies the vertically integrated supply chain
model in which the organization has direct control over each and every
component of the supply chain, while on the other end of the spectrum lies the
horizontally diversified supply chain model (ideally) in which the number of
participant is as large as the number of distinct parts of the supply chain. In a
-
7/31/2019 Or-Project Supply Chain
12/33
vertically integrated supply chain system, the organization can control every
component of the chain and can make various changes to the system to
optimize the chain very easily. But in a horizontally diversified supply chain
the tendency will be to optimize only the functions that the organization is
involved in, thus conscious efforts must be made by the various participants in
the supply chain for the integration of their respective components in the
supply chain. If an organization can be identified as the major/dominant
partner in the supply chain, then this organization has to take an initiative in
seeking the co-operation of the other participants in the supply chain.
The type and structure of the supply chain that is established depends on
many factors, some of the major factors are:
Geographical: If the supply chain is stretched across the globe then it maynot be possible to incorporate some of the principles of lean production
like JIT delivery, flexible manufacturing, and co-ordination among
suppliers and customers. It can lead to uncertain transportation schedules,
unpredictable lead time and may need larger inventory carriage.
Cultural:The difference in the culture of the participants in the chain(the difference can be due to geographical factors or corporate practices)
can lead to friction and distrust. This may hamper the development of close
ties.
Government Legislation: The laws of the country may prohibit thesharing of information about some facet of the supply chain and thus, may
lead to a restrictive participation by one or more participant in the supply
chain.
-

Time: Just as among individuals, organizations require time before trustcan be built up. The first phase in any relationship is manifest as
confrontation that essentially means that participants in the chain try to
win at the cost of other participants. And, the last phase is exemplified by
total trust and working together of organizations. The information sharing
behavior in the first phase is almost zero, while in the integrated
relationship the information sharing is mutual and free about the common
concerns. In between the two phases lies a continuum of phases.

Demand Forecasting
What is a demand forecast?
Demand forecasting is the activity of estimating the quantity of a
product or service that consumers will purchase. Demand forecasting involves
techniques including both informal methods, such as educated guesses, and
quantitative methods, such as the use of historical sales data or current data
from test markets. Demand forecasting may be used in
making pricing decisions, in assessing future capacity requirements, or in
making decisions on whether to enter a new market.
A demand forecast is the prediction of what will happen to your
company's existing product sales. It would be best to determine the demand
forecast using a multi-functional approach. The inputs from sales and
marketing, finance, and production should be considered. The final demand
forecast is the consensus of all participating managers. You may also want to
put up a Sales and Operations Planning group composed of representativesfrom the different departments that will be tasked to prepare the demand
forecast.
Determination of the demand forecasts is done through the following steps:
Determine the use of the forecast
Select the items to be forecast
Determine the time horizon of the forecast
Select the forecasting model(s)
Gather the data

Need for Demand Forecasting
The significance of demand or sales forecasting in the context of
business policy decisions can hardly be overemphasized. Sales constitute the
-
7/31/2019 Or-Project Supply Chain
16/33
primary source of revenue for the corporate unit and reduction for sales gives
rise to most of the costs incurred by the firm.
Demand forecasting is essential for a firm because it must plan its
output to meet the forecasted demand according to the quantities demanded
and the time at which these are demanded. The forecasting demand helps a
firm to arrange for the supplies of the necessary inputs without any wastage
of materials and time and also helps a firm to diversify its output to stabilize
its income overtime.
The purpose of demand forecasting differs according to the type of
forecasting.
(1) The purpose of the Short term forecasting:
It is difficult to define short run for a firm because its duration may
differ according to the nature of the commodity. For a highly sophisticated
automatic plant 3 months time may be considered as short run, while for
another plant duration may extend to 6 months or one year. Time duration
may be set for demand forecasting depending upon how frequent the
fluctuations in demand are, short- term forecasting can be undertaken by
affirm for the following purpose;
Appropriate scheduling of production to avoid problems of over productionand under- production.
Proper management of inventories Evolving suitable price strategy to maintain consistent sales Formulating a suitable sales strategy in accordance with the changing
pattern of demand and extent of competition among the firms.
-
7/31/2019 Or-Project Supply Chain
17/33
Forecasting financial requirements for the short period.(2) The purpose of long- term forecasting:
The concept of demand forecasting is more relevant to the long-run that
the short-run. It is comparatively easy to forecast the immediate future than
to forecast the distant future. Fluctuations of a larger magnitude may take
place in the distant future. In fast developing economy the duration may go up
to 5 or 10 years, while in stagnant economy it may go up to 20 years. More
over the time duration also depends upon the nature of the product for which
demand forecasting is to be made. The purposes are;
Planning for a new project, expansion and modernization of an existing unit,diversification and technological up gradation.
Assessing long term financial needs. It takes time to raise financial resources. Arranging suitable manpower. It can help a firm to arrange for specialized
labour force and personnel.
Evolving a suitable strategy for changing pattern of consumption.
Challenges Faced in Demand Forecasting
A small retailer may not need and afford a full-fledged demand forecasting
analysis. However, with increasing number of bigger retailers entering the
market demand forecasting becomes feasible. Firms face a multitude of
challenges due to the following factors:
1. Scale of forecast (how many goods to include in the forecast?)2. sporadic demand (erratic sales for many items in the store)3. introduction of new goods
-
7/31/2019 Or-Project Supply Chain
18/33
4. changing prices and promotions
Large scale forecasting. A big retailer may have thousands of items per shop.
Since forecasting is an important yet expensive task, the retailer can not
forecast for all goods it sells. Though it is infeasible to manually forecast the
demand of all the products, it is possible to use automated tools to do so. In
most cases, quality forecasts can be obtained from the automated tool and the
expert analysts can be employed to forecast few of the most important
products. This reduces the burden from the humans but requires lot of
compute power available.
What to optimize. Total sale volumes, total revenue earned, total profits,
maximize margin are many different objectives that a firm may use and may
receive optimized goods in stock. Creditability of such optimization
decisions pivots on the ability to correctly predict the sales. This is usually
based on prior data about the same product or close substitutes. It may also
be based upon analysis done at another location with similar buyer patterns.
When to restock. Slow moving goods may be restocked leisurely compared
to fast moving goods. It is important for retailers to provide the customers the
specific goods that the customer asks of the retailer. Under stocking would
cause unsatisfied customers who may quickly move to other stores. Over
stacking may increase the money locked up in inventory. Hence, the retailer
should aim at a replenishment policy by which the rack never gets empty and
never overflows. When close substitutes are available for some products, the
-
7/31/2019 Or-Project Supply Chain
19/33
retailer may compensate for a lower current stock in one good with another
one.
JUDGEMENTAL
The main methods in these categories are as follows:
Unaided Judgement:
It is common practice to ask experts what will happen. This is a good
procedure to use when,
Experts are unbiased,
Large changes are unlikely,
Relationships are well understood by experts (e.g., demand goes up when
Prices go down),
Experts possess privileged information,
Experts receive accurate and well-summarized feedback about their
forecasts.
Delphi:
To forecast with Delphi the administrator should recruit between five
and twenty suitable experts and poll them for their forecasts and reasons. The
administrator then provides the experts with anonymous summary statisticson the forecasts, and experts reasons for their forecasts. The process is
repeated until there is little change in forecasts between rounds - two or three
rounds are usually sufficient. The Delphi forecast is the median or mode of the
experts final forecasts.
-
7/31/2019 Or-Project Supply Chain
20/33
Judgemental Decomposition:
The basic idea behind judgemental decomposition is to divide the
forecasting problem into parts that are easier to forecast than the whole. One
then forecasts the parts individually; using methods appropriate to each part.
Finally, the parts are combined to obtain a forecast.
Expert Systems:
As the name implies, expert systems are structured representations of
the rules experts use to make predictions or diagnoses. For example, if local
household incomes are in the bottom quartile, then do not supply premium
brands.
Expert systems forecasting involves identifying forecasting rules used
by experts and rules learned from empirical research.
Developing an expert system is expensive and so the method will only
be of interest in situations where many forecasts of a similar kind are
required. Expert systems are feasible where problems are sufficiently well-structured for rules to be identified.
Simulated interaction:
Simulated interaction is a form of role playing for predicting decisions
by people who are interacting with others. To use simulated interaction, an
administrator prepares a description of the target situation, describes the
main protagonists roles, and provides a list of possible decisions. Role players
adopt a role and read about the situation. They then improvise realistic
interactions with the other role players until they reach a decision; for
-
7/31/2019 Or-Project Supply Chain
21/33
example to sign a trial one-year exclusive distribution agreement. The role
players decisions are used to make the forecast.
Intentions and Expectations Survey:
With intentions surveys, people are asked how they intend to behave in
specified situations. In a similar manner, an expectations survey asks people
how they expect to behave.
To forecast demand using a survey of potential consumers, the
administrator should prepare an accurate and comprehensive description of
the product and conditions of sale. He should select a representative sample of
the population of interest and develop questions to elicit expectations from
respondents. Bias in responses should be assessed if possible and the data
adjusted accordingly. The behavior of the population is forecast by
aggregating the survey responses.
How is demand forecast determined?
There are two approaches to determine demand forecast (1) the
qualitative approach, (2) the quantitative approach. The comparison of these
two approaches is shown below:
Description Qualitative Approach Quantitative Approach
Applicability Used when situation is
vague & little data exist
(e.g., new products and
technologies)

Qualitative Forecasting Methods
Your company may wish to try any of the qualitative forecasting
methods below if you do not have historical data on your products' sales.
Qualitative Method Description
Jury of executive
opinion
The opinions of a small group of high-level
managers are pooled and together they estimate
demand. The group uses their managerial
experience, and in some cases, combines the
results of statistical models.
Sales force
composite
Each salesperson (for example for a territorial
coverage) is asked to project their sales. Since
the salesperson is the one closest to the
-
7/31/2019 Or-Project Supply Chain
23/33
marketplace, he has the capacity to know what
the customer wants. These projections are then
combined at the municipal, provincial and
regional levels.
Delphimethod A panel of experts is identified where an expert
could be a decision maker, an ordinary
employee, or an industry expert. Each of them
will be asked individually for their estimate of
the demand. An iterative process is conducteduntil the experts have reached a consensus.
Consumer market
survey
The customers are asked about their purchasing
plans and their projected buying behavior. A
large number of respondents is needed here to
be able to generalize certain results.
Quantitative Forecasting Methods
There are two forecasting models here (1) the time series model and
(2) the causal model. A time series is a s et of evenly spaced numerical data
and is obtained by observing responses at regular time periods. In the time
series model, the forecast is based only on past values and assumes that
factors that influence the past, the present and the future sales of your
products will continue.
On the other hand, t he causal model uses a mathematical technique
known as the regression analysis that relates a dependent variable (for
-
7/31/2019 Or-Project Supply Chain
24/33
example, demand) to an independent variable (for example, price,
advertisement, etc.) in the form of a linear equation. The time series
forecasting methods are described below:
Time Series Forecasting
Method
Description
Nave
Approach
Assumes that demand in the nextperiod is the same as
demand in most recentperiod; demand pattern may
not always be that stable
For example:
If July sales were 50, then Augusts sales will also be
50
Time Series Forecasting
Method
Description
Moving
Averages (MA)
MA is a series of arithmetic means and is used if little
or no trend is present in the data; provides an overall
impression of data over time
A simple moving average uses average demand for a
fixed sequence of periods and is good for stable
demand with no pronounced behavioral patterns.
Equation:
-
7/31/2019 Or-Project Supply Chain
25/33
F 4 = [D 1 + D2 + D3] / 4
F forecast, D Demand, No. Period
A weighted moving average adjusts the movingaverage method to reflect fluctuations more closely by
assigning weights to the most recent data, meaning,
that the older data is usually less important. The
weights are based on intuition and lie between 0 and 1
for a total of 1.0
Equation:
WMA 4 = (W) (D3) + (W) (D2) + (W) (D1)
WMA Weighted moving average, W Weight, D
Demand, No. Period
Exponential
Smoothing
The exponential smoothing is an averaging method
that reacts more strongly to recent changes in demandby assigning a smoothing constant to the most recent
data more strongly; useful if recent changes in data are
the results of actual change (e.g., seasonal pattern)
instead of just random fluctuations
F t + 1 = a D t + (1 - a ) F t
Where
F t + 1 = the forecast for the next period
D t = actual demand in the present period
-
7/31/2019 Or-Project Supply Chain
26/33
F t = the previously determined forecast for the
present period
= a weighting factor referred to as the smoothing
constant
Time Series
Decomposition
The time series decomposition adjusts the
seasonality by multiplying the normal forecast by a
seasonal factor
Forecast Accuracy and Key Performance Indicators (KPIs)
In inventory control operations, demand forecasting is usually
performed for each stock item SKU stock keeping unit. Different metrics,
called KPIs (key performance indicators), can be used to ensure that
customer service remains at or above acceptable levels for each SKU. Common
KPIs include case fill and order fill.
To fulfill these objectives, its necessary to keep a certain level of safety
stock . However, holding excess safety stock can lead to higher inventory
costs, and furthermore, increases risk that some inventory will have to be
written off during the later stages of the product lifecycle.
If supply chain managers are interested in reducing safety stock, there
are several methods they can use, foremost of which is demand planning.
Increasing forecasting accuracy, then, is a primary goal in the supply chain.

Forecast accuracy can be calculated using a formula called MAPE Mean
Absolute Percent Error. The equation is as follows:
Error % = |Actual Forecast|/Actual
(note that |x| means the absolute value of x)
The reason that absolute value bars are used in mean absolute percent error
is because for statistical reasons, magnitude of error is often more important
than the sign.
Forecast accuracy is a metric that is inversely related to MAPE (as MAPE
increases, FA decreases). The equation for forecast accuracy is:
FA = 100 MAPE
(expressed as a percentage)
SCM Disaster
Businesses now not only need to operate at a lower cost to compete, it
must also develop its own core competencies to distinguish itself from
competitors and stand out in the market. Supply chain management
plays an important role in successful running of any business. SCM
has allowed company to rethink their entire operation and restructure it so
that they can focus on its core competencies and outsource processes
that are not within the core competencies of the company.
But the opposite effect of the SCM also comes into the view at times.

Nike Inc.
Nike Inc. is a major publicly traded sportswear and equipment
supplier based in the United St ate s. Th e co mpa ny is

Po rt l an d metropolitan area. It is the world's leading supplier
of athletic shoes and apparel and a major manufacturer of sports
equipment with revenue in excess of $18.6 billion USD in its fiscal year 2008
(ending May 31, 2008). As of 2008, it employed more than 30,000 people
worldwide. Nike an d Pr ec is io n Ca st pa rt s ar e

January 25, 1964 as Blue Ribbon Sports by Bil l Bower man and Philip
Knight, and officially became Nike, Inc. in 1978. The company takes its name
from Nike, the Greek goddess of victory equipment; the company operates
retail stores under the Nike town name. Nike sponsors many high profile
athletes and sports teams around the world , with the highly recognized
trademarks of "Just do it" and the Swoosh logo.
Nikes Supply Chain: Failure and Eventual Success
During the 1970s retailers would make their orders with Nike 9 months
in advance before their delivery date. The orders were then sent to Nikes
manufacturers all over the world. At the beginning this process worked well

and allowed Nike to deliver its orders on time. However, during the 1980s and
1990s Nikes business grew dramatically and customers became more
demanding about style, comfort and variety leading Nikes forecasting,
manufacturing and distribution to become very complex.
In 1999, profits dropped by 50 percent due to supply chain factors. The
situation led to the adoption of Nikes supply chain project called NSC. The
project attempted to improve the failing forecasting and order activities in
Nike. However this didnt work well for Nike, so it acquired and implemented
i2 technologies demand forecasting system at a cost of $40 million. The
objectives of this project were to forecast over 1 million stock keeping units
(SKUs). Algorithms were used to generate Nikes forecasts for manufacturing.
However, later in 2000, the forecasts were found to be faulty, causing Nike to
over manufacture some products while struggling to meet the demand for
other products. It took Nike between 6 and 9 months to overcome its
manufacturing problems and more than 2 years to make up for its financial
loss.
After analyzing its i2Technologies, Nike learned that it needed a more
adequate training of users, more comprehensive testing for the application
and a more careful integration of the application with other information
systems. The review of the project found that there was too much reliance on
forecasts generated by algorithms without using any judgment to evaluate the
forecasts.
By 2004, Nike had an integrated and efficient supply chain with i2
technologies forecasting system, SAPs ERP system, and Siebels CRM systems.
Nike spent 6 years and $800 million on the project.

Nikes 2001 Planning System Perplexity
The companys headquarters are located in Beaverton, Oregon
in the US. The company had a good supply chain management wherein the
company was in a practice of never manufacturing the products. Instead
the company used to outsource the manufacturing process directly to
the suppliers. These suppliers were known as the contractors.
Future program:
It was in the year 1975 when the Nike introduced the Future Program.Under this program the Nikes global operations were broadly divided into 5
geographic regions. This was aimed towards obtaining better operations and
effective systems. During this era, toward the end of the 1990s the supply
chain management seemed to be ineffective and inadequate. There
were problems like ineffective forecasting and managing the changing trends.
NSC Project:
Further in the year 2000 Nike launched the New Safe
Confinement (NSC) project. This project aimed at implementing its ERP,
Supply Chain, & CRM Software onto a single SAP Platform. This project
ultimately proved to be a big disaster for the Nikes operations.
The Failure:
I n the s p r ing of 2001, N ike b la med i2 Tec hnologies for a
ma ss iv e sa le s- an d- earnings shortfall. Nike posted a profit of only
$97 million that quarterat least $48 million below forecast. Nike said
the culprit was i2's demand-forecasting and supply-chain-management

systems. The supply-chain software was supposed to reduce the
amount of rubber; canvas and other materials that Nike needed to
produce its shoes. It was also supposed to help make sure Nike built
more of the shoes customers wanted and fewer of the ones they didn't.
Instead, Nike was left with far too many of the wrong shoes and not nearly
enough pairs of its hottest sellers.
The Reason:
The total cost of i2's demand-forecasting and supply-chain-management
software was only about $40 million. The other $360 million was
spent over five yearson customer-relationship and enterprise-planning
software from SAP. This whole project aiming at effective forecasting proved
to be a big SCM failure for the company. This meant huge financial losses
for the company. The reasons for the i2s software implementation were
finally designated over the following reasons:
1. Third party integrator2. Inexperience of i23. Customization4. Trying to forecast too far out ahead5. Pilot test6. Lack of training,7. Inadequate information8. Problems in smooth integration9. Changing market conditions10. Complication of NSC project11. Review meetings

The Result:
This res ulted in huge p rof i t los s for the c omp a ny.
It ef fec te d th e co mpa ny reputation a lot. Massive sales
and earnings shortfall were observed. Nike was left with far too many
of the wrong shoes and not nearly enough pairs of its hottest sellers. Thus
company understood the importance of the SCM and forecasting. Forecasting
for the Nike was extremely important. It was important for them to
determine the quantities. An important feature that the company
understood regarding its SCM was that it needed to lay attention on the make
to order rather than the make to stock policy. Company also understood
that in a type of business that the company is in, forecasting plays an
important role in reducing the supply time. For all this to obtain it was
important for the company to obtain the best forecasting. Nike further
improved its supply chain management by installing well equipped and
competent system. Its continuous interaction with the consumers on
the web portal proved to be the best feature. Herein the consumers
achieve the supreme level of customization of the products. Nike also
improved itself by proper analysis of the data and implementation. Feedback
as in any other industry plays an important role in Nike today. Nike
obtains continuous feedback from the suppliers and the consumers.

Conclusion:
Hence supply chain management for any company plays an important
role in successful running of a company. The reverse effect of the SCM
can also be experienced if the implementation of the SCM processes is
not done in the best way. Implementation is a complex procedure and
it must be tackled in the best way. Evaluating pros and c ons of any
project beforehand is also equally important. A pilot project can
be turn around the fate of any business if handled correctly
