UNIT IV TQM TOOLS & TECHNIQUES II

Quality circles – Quality Function Deployment (QFD) – Taguchi quality loss function – TPM – Concepts, improvement needs – Cost of Quality – Performance measures.

Quality CircleWhat is quality circle?

A group of employees who perform similar duties and meet at periodic intervals, often with management, to discuss work-related issues and to offer suggestions and ideas for improvements, as in production methods orquality control,calledquality circle.

Therefore quality circle is nothing but a small group of employees who come together to discuss with the management issues related to either quality control or improvement in production methods form a Quality Control Circle (QCC). These employees usually work in the same areas, and voluntarily meet on a regular basis to identify, analyze and solve their problems.

Key Characteristics of quality circle: 1. A circle, usually consisting of 6-8 members, from the same section. 2. Membership of a Quality Circle is voluntary. 3. Circle members should meet regularly, ideally once a week, in particular place also in

particular time. 4. Circle members select a name for their circle in the first meeting and elect a leader to

conduct the meetings. 5. Members are specially trained in problem solving and analysis techniques in order to play

their role effectively. 6. Circle works on a systematic basis to identify and solve work - related problems for

improving quality and productivity not just discussing them. 7. The management must ensure that solutions are implemented quickly once they have been

accepted 8. The management must give appropriate and proper recognition to solution

Why Quality Circle: It is said that 95% of the problems in workshops can be solved through quality control tools. The Japanese have experienced this! The quality control tools useful for QCCs are Pareto Diagrams, Cause-and-Effect Diagrams, Stratification, Check Sheets, Histograms, Scatter Diagrams, Graphs and Control Charts. Also, logical thinking and experience are a must for solving problems. Therefore the main objectives of QC are: 1. To improve quality and productivity.2. To reduce the cost of products or services by waste reduction, safety, effective

utilization of resources, avoiding unnecessary errors and defects. 3. To identify and solve work-related problems and interfere with production as a team.

Page 2: ishareyoublog.files.wordpress.com file · Web viewUNIT IV TQM TOOLS & TECHNIQUES II. Quality circles – Quality Function Deployment (QFD) – Taguchi quality loss function – TPM

4. To tap the creative intelligence of people working in the org. and make full use of human resources.

5. To improve communication within the organization. 6. To improve employees loyalty and commitment to the organization and its goals. Promoting

Morale of employees) 7. To build a happy, bright, meaningful work environment. 8. To satisfy the human needs of recognition, achievement and self development

The benefits of introducing a quality control circle program in the work place are many.

1. Heightened quality awareness reveals faults in the system that might obstruct good practices.

2. It improves the quality of your firm’s products and services, thereby increasing the value of your brand, and securing your customers’ confidence. The quality of customer relationship management can be further enhanced by using help desk software from the likes of pro software.

3. The people who are part of the quality control circle will feel a sense of ownership for the project.4. Higher yields and lower rejection rates also result in enhanced job satisfaction for workers,

which in turn drives them to contribute more. 5. A quality control circle program also brings about improved two-way communication between the

staff and the management. 6. Finally, the financial benefits will certainly exceed the costs of implementing the program.7. A study revealed that some companies improved their savings ten fold!

Basic Organizational Structure of QC:

A quality circle should have an appropriate organizational structure for its effective and efficient performance. The structure may vary from one org. to another, but it is useful to have basic framework as a model:

Page 3: ishareyoublog.files.wordpress.com file · Web viewUNIT IV TQM TOOLS & TECHNIQUES II. Quality circles – Quality Function Deployment (QFD) – Taguchi quality loss function – TPM

In a typical organization, the structure of a QC may consist of the following elements: 1. Steering committee - Gen. manager / works manager, rep. from top management, rep. of

human resource development and a rep. of employees’ union. 2. Coordinator: an administrative officer/ personnel officer from middle level

management.3. Facilitator: senior supervisory officer / foreman. A facilitator may manage up to 10

circles. A facilitator is usually from one of the three departments - quality control, production or training.

4. Circle Leader: circle leaders may be from the lowest level of supervisors. A circle leader organizes and conducts circle activities.

5. Circle members: line and / or staff workers ( circle members should attend all meetings as far as possible, offer suggestions and ideas, participate actively in group processes, and attain training seriously.

How to implement quality circle: 1. Firstly, the management is informed about the quality control circle process that is being

planned. 2. A committee is formed, and key persons such as a coordinator and in-house coach are

selected. 3. The scope is defined, and areas of application identified. 4. First-line supervisors in the identified areas are given QCC presentations. It is

important to make these impressive, and valuable tips on the subject are available. 5. This is followed up with extensive training for coordinators and middle management

on the process and their roles. 6. Employees are invited to become members of a circle, and trained suitably once they sign

up. Thus, a circle is formed and begins work. These may give rise to other circles. 7. Problems are discussed and solved in a systematic manner in the QCCs. It is very

important that solutions are implemented as quickly as possible, to maintain the momentum.

Usually QCC programs must operate in all sections of the company i.e., in the offices, service operations and manufacturing. But remember, while the size of the company is not important to a program's success, the following factors certainly are:

1. Voluntary participation. 2. Management support. 3. Employee empowerment. 4. Training programs. 5. Team work. 6. Problem solving skills.

QUALITY FUNCTION DEPLOYMENT

(1) What is Quality Function Deployment(QFD)? Explain its uses. Quality Function Deployment is a planning tool used to fulfill customer expectations. Quality Function Deployment focuses on customer expectations or requirements, often

referred to as voice of the customer.QFD TEAM :

There are two types of teams namely

1. Team for designing a new product

2. Team for improving an existing product

BENEFITS OF QFD :

1. Improves Customer satisfaction Creates focus on customer requirements Uses competitive information effectively Prioritizes resources Identifies items that can be acted upon

2. Reduces Implementation Time Decreases midstream design changes Limits post introduction problems Avoids future development redundancies

Promotes Team Work

Based on consensus Creates communication Identifies actions

3. Provides Documentation Documents rationale for design Adds structure to the information Adapts to changes (a living document)

TAGUCHI’S QUALITY LOSS FUNCTION

(5) What is Taguchi’s Loss Function?

TAGUCHI’S QUALITY LOSS FUNCTION

INTRODUCTION

Taguchi Methods is a statistical methods developed largely by GENICHI TAGUCHI to improve quality of manufactured goods.

The philosophy of off-line quality control.

Innovations in the design of experiments.

Taguchi Loss Function Definition

Taguchi defines Quality as “the loss imparted by the product to society from the time the product is shipped.”

LOSS = Cost to operate, Failure to function, maintenance and repair cost, customer satisfaction, poor design.

Product to be produced “being within specification”

Taguchi’s Vs Traditional Approach

Taguchi’s Quadratic Quality Loss Function

Quality Loss Occurs when a product’s deviates from target or nominal value.

Page 8: ishareyoublog.files.wordpress.com file · Web viewUNIT IV TQM TOOLS & TECHNIQUES II. Quality circles – Quality Function Deployment (QFD) – Taguchi quality loss function – TPM

8

Deviation Grows, then Loss increases.

Taguchi’s U-shaped loss Function Curve.

Taguchi’s U-shaped loss Function Curve.

Formula to find Taguchi’s Loss FnTaguchi uses Quadratic Equation to determine loss Curve

L (x) = k (x-N)²

Where L (x) = Loss Function,

k = C/d² = Constant of proportionality, where C – Loss associated with sp limit

d - Deviation of specification from target value

x = Quality Features of selected product,

N = Nominal Value of the product and

(x-N) = Tolerance

Problem

A part dimension on a power tool is specified as 32.25±0.25.Company records show±0.25 exceeded & 75% of the returned fo replacement. Cost of replacement is Rs.12,500.Determine k & QLF.

Page 9: ishareyoublog.files.wordpress.com file · Web viewUNIT IV TQM TOOLS & TECHNIQUES II. Quality circles – Quality Function Deployment (QFD) – Taguchi quality loss function – TPM

9

Solution : Expected Cost of repair

C = 0.75(12500) = Rs 9,375

k = C/d²= 9375/(90.25)² = Rs 1,50,000

QLF =L (x) 1,50,00(x-N)

Taguchi’s Quality Loss Function concept combines cost, target and variation in one metric with specifications being of secondary importance.

Page 10: ishareyoublog.files.wordpress.com file · Web viewUNIT IV TQM TOOLS & TECHNIQUES II. Quality circles – Quality Function Deployment (QFD) – Taguchi quality loss function – TPM

10

Taguchi has defined quality as the loss imparted to society from the time a product is shipped. Societal losses include failure to meet customer requirements, failure to meet ideal performance and harmful side effects.

CUSTOMERS PERCEIVE QUALITY AS MEETING THE TARGET RATHER THAN JUST MEETING THE SPECIFICATIONS.

There are three common quality loss functions

1. Nominal - the - best.

2. Smaller - the - better.

3. Larger - the - better.

NOMINAL – THE – BEST :

Although Taguchi developed so many loss functions, many situations are approximated by the quadratic function which is called the Nominal – the – best type.

The quadratic function is shown in figure. In this situation, the loss occurs as soon as the

performance characteristic, y, departs from the target τ.

At τ, the loss is Rs. 0.

At LSL (or) USL, the loss is Rs. A.

The quadratic loss function is described by the equation L = k (y - τ) 2.

Where,

L = cost incurred as quality deviates from the target.

y = Performance characteristic

τ = target

k = Quality loss coefficient.

The loss coefficient is determined by setting ∆ = (y – τ), the deviation from the target. When ∆ is the USL (or) LSL, the loss to the customer of repairing (or) discarding the product is Rs. A.

Thus,

K = A / (y – τ)2 = A / ∆2 .

SMALLER – THE – BETTER :

The following figure shows the smaller – the – better concepts.

The target value for smaller – the – better is 0. There are no negative values for the performance characteristic.

The radiation leakage from a microwave appliance, the response time for a computer, pollution from an automobile, out of round for a hole etc. are the performance characteristics for this concept.

LARGER – THE – BETTER :

The following figure shows the concept of the Larger – the – better.

(6) Define TPM(Total Productive Maintenance). Explain in detail TPM steps.

Total Productive Maintenance (TPM) is defined as keeping the running plant and equipment at its highest productive level with the co-operation of all areas of the organization.

Predictive and Preventive maintenance are essential to building a foundation for a successful TPM environment. Predictive Maintenance is the process of using data and statistical tools to determine when a piece of equipment will fail. Preventive Maintenance is

Page 13: ishareyoublog.files.wordpress.com file · Web viewUNIT IV TQM TOOLS & TECHNIQUES II. Quality circles – Quality Function Deployment (QFD) – Taguchi quality loss function – TPM

13

the process of periodically performing activities such as lubrication on the equipment to keep it running.

OBJECTIVES OF TPM :

1. To maintain and improve equipment capacity.

2. To maintain equipment for life.

3. To use support from all areas of the operation.

4. To encourage input from all employees.

5. To use teams for continuous improvement.

TPM PHILOSOPHY – CONCEPT OF TPM :

Total Productive Maintenance (TPM) is an extension of the Total Quality Management (TQM) philosophy to the maintenance function.

TPM has the following steps:

1. Management should learn the new philosophy of TPM.

2. Management should promote the new philosophy of TPM.

3. Training should be funded and developed for everyone in the organization.

4. Areas of needed improvement should be identified.

Loss measurements to identify improvement needs are

Down time losses Reduced speed losses Poor quality losses

5. Performance goals should be formulated.

6. An implementation plan should be developed.

7. Autonomous worth groups should be established.

ISO 9000 STANDARDSNeed for ISO 9000- ISO 9001-2008 Quality System – Elements, Documentation, Qualityauditing- QS 9000 – ISO 14000 – Concepts, Requirements and Benefits – Case studiesof TQM implementation in manufacturing and service sectors including IT.

(1) Give an overview and evolution of of IS 9000 series of standards .The International Organization of Standardization (ISO) was founded in

1946 in Geneva, Switzerland. The development of International Standards is to facilitate the exchange of goods and services worldwide. ISO consists of more than 90 country members.

The ISO Technical Committee (TC) developed a series of International Standards for Quality Systems, which were first published in 1987. The standards (ISO 9000,9001, and 9004) were intended to be advisory and developed for use in two-party contractual situations and internal auditing.

These standards were adoted by European Community and have been accepted worldwide with emphasis on quality and economic competetiveness.

The fourth edition of ISO 9001 was released in the year 2008 and it replaces the third edition (ISO9001 : 2000), which have been amended to clarify the points in the text and also to enhance the compatibility with ISO 14001 : 2004.

Most countries have adopted ISO 9000 series as their national standards.

(2) Explain briefly the scope and purpose of ISO 9000 Series standards.

The ISO 9000 series Stadnards is generic in scope. By design, the series can be tailored to fit any organization ‘s needs. Whether it is large or small, a manufaturerer or a service organization. It can be applied to construction, engineering, health care, legal, and other professional services as well as the manufacturing of anything from nuts and bolts to spacecraft. Its purpose is to unify quality terms and defi nitions used by industrialized nations and use those terms to demonstrate the supplier’s capability of controlling the processes.

In very simplified terms , the standards require an organization to say what it is doing to ensure quality, then do what it says,and, finally document or prove that it has done what it said.

(5) What are Quality Audits? Explain in detail the types of audits.

Quality Audit

Systematic, independent and documented process for obtaining audit evidence and evaluating it objectively to determine the extent to which audit criteria are fulfilled.

Types of audit

3 types

o Process audits

o Product audits

o System audits

Process audits

• Evaluation of the content and effectiveness of specific processes and work activities

• To confirm the process parameters and improve capability of the process

• To ensure the realization of process quality characteristics

Page 24: ishareyoublog.files.wordpress.com file · Web viewUNIT IV TQM TOOLS & TECHNIQUES II. Quality circles – Quality Function Deployment (QFD) – Taguchi quality loss function – TPM

24

• To ensure improvement of process control during service provision

• Product audits

-To identify opportunities for improvement to establish the quality level of units before final inspection and testing

-To establish the capability of the inspection function

-To determine the usefulness of inspection/tests

• Audits are distinguished by the party requesting:

• 1st party audit (internal audits) – the auditee audits its own quality system according to a quality standard.

• 2nd part audits (supplier audits) – the customer audits the supplier’s quality system

• 3rd party audits – these are external certification audits by an independent institution in order to certify the quality system

Products audits

Investigation of products conformance to specified characteristics

-To obtain additional neutral assessment of product’s level of quality

-To obtain additional assurance that specified quality requirements are met

System audits

• Evaluation all the elements of the quaity system in order to:-

• Verify usefulness, suitability and effectiveness

• Verify adequate documentation

• Verify compliance with requirements

• Determine weak points

Purpose of audits

• Registration / certification audit

• Verify that the organization's QMS meet the requirements of ISO 9001 : 2000

Internal audit

• Identify opportunities for improvement• Maintain ISO 9001 certification

(6) What are the objevtives of Internal audit?

Objectives of the Internal audit

• To verify conformance to applicable standards

• To verify conformance to documented procedures

• To verify effectiveness of the processes in the system

• To identify opportunities to improve the system

• Creating and environment for successful audits (1)

(7) Discuss in detail the purpose of Quality Auditing.

QUALITY AUDITING

The term Audit refers to a regular examination and checking of accounts or financial records, settlement or adjustment of accounts.

It also refers to checking, inspection and examination of Production Processes.

PURPOSE OF QUALITY AUDIT :

To establish the adequacy of the system. To determine the effectiveness of the system. To afford opportunities for system analysis. To help in problem solving. To make decision making easier etc.

TYPES OF QUALITY AUDIT :

1. First – Party Audit.2. Second – Party Audit.3. Third – Party Audit.

Quality audit can also be classified on the basis of the area taken into account for the audit such as

System Audit. Process Audit. Product Audit. Adequacy Audit. Compliance Audit.

(8) Discuss the evolution of ISO 14000, the Environmental Management Systems (EMS).

ISO 14000 – ENVIRONMENTAL MANAGEMENT SYSTEM (EMS)

The overall aim of the Environmental Management systems is to provide protection to the environment and to prevent pollution.

The success of ISO 9000 along with increased emphasis on Environmental issues were instrumental in ISO’s decision to develop Environmental Management Standards.

In 1991, ISO formed the Strategic Advisory Group on the Environment (SAGE) which led to the formation of Technical Committee (TC) 207 in 1992.

Mission of TC207 is to develop standards for an Environmental Management System (EMS) which was identified as ISO 14000.

TC 207 has Established six sub-committees1. Environmental Management System (EMS)2. Environmental Auditing (EA)3. Environmental labeling (EL)4. Environmental Performance Evaluation (EPE)5. Life-Cycle Assessment (LCA)6. Terms & Definitions

Environmental Management System (EMS) :

EMS has two Evaluation Standards. They are

1. Organization Evaluation Standards 2. Product Evaluation StandardsREQUIREMENT OF ISO 14001

There are six elements

1. GENERAL REQUIREMENTS

EMS should include policy, planning implementation & operation, checking & corrective action, management review.

2. ENVIRONMENTAL POLICY (Should be based on mission)

The policy must be relevant to the organization’s nature. Management’s Commitment (for continual improvement & preventing pollution). Should be a framework (for Environmental objectives & Targets). Must be Documented, Implemented, & Maintained.

3. PLANNING

Environmental Aspects Legal & other Requirements Objectives & Targets Environmental Management Programs

4. IMPLEMENTATION & OPERATION Structure & Responsibility Training, Awareness & Competency Communication EMS Documentation Document Control Operational Control Emergency Preparedness & Response

5. CHECKING & CORRECTIVE ACTION Monitoring & Measuring Nonconformance & Corrective & Preventive action Records EMS Audit

6. MANAGENMENT REVIEW Review of objectives & targets Review of Environmental performance against legal & other requirement Effectiveness of EMS elements Evaluation of the continuation of the policy

(9) Discuss in detail ISO 14000 series standards , its scope, concepts and steps in its implementation.

ISO 14000: Environmental   Standards

ISO 14000

The International Organization for Standards published its Quality Management System (ISO9000) in 1987.  ISO9000 became an instant world wide success.

In 1991, ISO formed Strategic Advisory Group on the Environment (SAGE). The purpose of formation of this group was world wide increase in emphasis of management of environmental issues a part of quality management systems. This group proposed the formation of Technical Committee to develop standards that deal with environmental management system. This technical committee, TC 207 developed the standards called ISO14000.

The EMS is part of a comprehensive management system that addresses with the overall business activities, including its products and services, affect the environment.

ISO14000 Series Standards

ISO14000 is a generic standard. When we state the term generic, we mean that- like ISO9000-it is not an industry specific standard.

The series is divided into two separate areas-the organization evaluation standards  and the product evaluation standards. The first deals with Environmental Management System (EMS), Environmental Auditing (EA), and Environmental Performance Evaluation (EPE), whereas later deals with Environmental Aspects in Product Standards (EAPS), Environmental Labeling (EL), and Life-Cycle Assessment (LCA).

See following figures to understand the division of standards as mentioned above:

 Concepts of ISO 14001:2004 Standards

In this post we will particularly discuss ISO 14001:2004 because this standards is the heart of all the environmental standards. This standard provides organizations with the elements of for an

Page 29: ishareyoublog.files.wordpress.com file · Web viewUNIT IV TQM TOOLS & TECHNIQUES II. Quality circles – Quality Function Deployment (QFD) – Taguchi quality loss function – TPM

29

environmental systems, which can be integrated into other management systems to help achieve environmental and economic goals.

This standard provide guidelines for registration and/or self-declaration of the organization’s environmental management systems. This standard is written in a manner that it can be applicable to all types and sizes of organizations. This standard is also capable to accommodate diverse geographical, cultural, and social conditions.

The demonstration of successful implementation of the system can be used to assure other parties that an appropriate EMS is in place. The basic approach to Environmental System can be understood with the help of following diagram:

Environmental Management System Model

ISO 14001:2004 works as follows:

As stated earlier in this post that ISO14000 is generic in nature. It does not  intend to specify the level of environmental performance of an organization. If that had been the case, ISO would have written it according to the specific activity of each business.

However, ISO has developed many other environmental standards that  deal with specific environmental standards. These standards are beyond the scope of ISO14001:2004 standards at the moment.

ISO14001:2004 provide a framework to the organizations so that they could communicate about EMS matters with the other stakeholders including customers, environmental regulators, the public and so forth.

It also provides framework to the organizations-irrespective of their current level of environmental maturity-to remain committed for environmental management and its continual improvement as well.
