ABSTRACT The past decade has witnessed the reemergence of quality as a key factor. If quality is not maintained then certainly survival would be difficult. Good business means good quality of the product and way to maintain quality is management. To fulfill customer’s expectation. It is important to upgrade the quality standards by doing continuous inspection, concentrating on prevention rather than correction and maintaining customer goodwill. The responsibility and managing quality rests with management and the enhancement to the traditional way of doing business is Total Quality Function Deployment (QFD) is an effective one. QFD is a disciplined approach to product design, engineering and production. It provides in depth evaluation of the product. This tool provides a historic reference to enhance future technology and to prevent design errors there by spending less time on redesign and modifications. In this paper the relationship between QFD and TQM has been discussed.

Quality Function Deployment: An Effective Tool for Total Quality Management 1. INTRODUCTION Quality itself has been defined as fundamentally relational: “quality is the ongoing process of building and sustaining relationships by assessing, anticipating and fulfilling stated and implied needs”. In other words “Quality is a momentary perception that occurs when something in our environment interacts with us in the pre intellectual awareness that comes before rational thought takes over and begins establishing orders. Judgment of the resulting order then reported as good or bad quality value”. Indian industries are facing challenges of survival due to liberation, privatization and globalization because of World Trade Organization (WTO). Many reputed Indian business house are either closed down or on verge of closing down to such competition. Indian products are facing challenges of quality, reduction in production cost and customer satisfaction in view of easy availability of imported goods. The situation has changed very fast and with multiple choices available to customers, economy is now converted into a buyers market. Now, the way to maintain quality is management and hence the responsibility for introducing and managing quality rests with management.

However, a prevailing but

erroneous assumption is that quality originates in the quality department and that quality professionals and responsible for goods and services offered. A corollary of this view is that quality can be improved through tighter controls and increased level of inspection i.e. quality is inspected in and not built in but in fact the quality problems are really the problems of those function and processes in the organization, whether t hey occurs in design, engineering, planning, manufacturing etc.

The solution of which is clearly the responsibility of

management. Therefore the emphasizing solution for up grading the quality standard and survival of Indian industries is “Total Quality Management”. Total Quality Management (TQM) is an enhancement to the traditional way of doing business. It is proven technique to guarantee survival in world class competition. TQM is for the most part common sense. Analyzing the three words we have: Total

= Quality involves everyone and all activities in the company.

= Degree of excellence of product or service provides.

Management = Quality can and must be managed with Act, Art, or manner of handling, controlling, directing etc. Hence, TQM = A process for managing quality; it must be continuous way of life; a philosophy of perpetual improvement in everything we do.

2. THE STEPS TO TOTAL QUALITY MANAGEMENT (TQM) 1. Pursue New Strategic Thinking 2. Know your Customers. 3. Set True Customer Requirements. 4. Concentrate on Prevention, Not Correction. 5. Reduce Chronic Waste. 6. Pursue a Continuous improvement Strategy. 7. Use Structural Methodology for Process Improvement. 8. Reduce Variation 9. Use a Balanced Approach. 10. Apply to All Functions

3. DIFFERENT TOOLS AND TECHNIQUE FOR TQM 3.1 STATISTICAL PROCESS CONTROL (SPC) One of the best technical tools for improving product and service quality is SPC. There are some basic techniques for SPC. The word statistical is somewhat misnomer since the first few techniques are not really statistical. Further more, this technical tool not only controls the process but has the capability to improve it as well. 3.2 QUALITY SYSTEM This is a two party system results in both the supplier and customer to participate in multiple audits, which can be extremely costly. registration system.

This practice is replaced by a third party

A quality system registration involves the assessment and periodic

surveillance audit of the adequacy of a supplier’s quality system by third party, who is a registrar.

When a system conforms to the registrar interpretation of the standard,

the

registrar issues a certificate of registration to supplier. This registration ensures customers or potential customers that a supplier has a quality system in place and it is being monitored and t here by eliminating the need of multiple audits.

3.3 BNECH MARKING Bench marking is a systematic method by which organizations can measure themselves against the best industries practices.

It promotes superior performance by

providing an organized frame work through which organizations learn how the “best in class” do things, understand these best practices differ from their own, and implement change to close the gap. Bench marking is increasingly a popular tool. It used extensively by both manufacturing and service organizations, including Xerox, AT & T, Motorola, Ford and Toyota. 3.4 QUALITY BY DESIGN Quality by Design principles is changing the way U.S. managers think and conduct business. Loosely defined, quality by design is the practice of using a multi disciplinary team to conduct conceptual thinking. Product design and production planning all at one time. 3.5 EXPERIMENTAL DESIGN Experimental design is one of the most powerful techniques for improving quality and increasing productivity. Through experimentation, changes are intentionally introduced into the process or system in order to observe their effect on the performance characteristics or response of the system or process. Any experiment that has the flexibility to make desired changes in the input variables of a process to observe the output response is known as experimental design. 3.6 PRODUCT LIABILITY Unproved technology creates hazards that are unknown prior to product use. Highly diverse and technically complicated product design has also increased the severity and frequency of injuries. The number of product accidents is roughly estimated at 50 million per year, at an annual cost to the nation $50 billion. Thus, there is a need to reduce the rest of injury and to compensate injured consumers. These accidents and injuries are reasons why the manufacture’s liability for product has increased. Manufacturers are in the best position to know what are the safest design of products, construction methods and modes of use. 3.7 FAILURE MODE AND EFFECT ANALYSIS (FMEA) FMEA is an analytical technique (paper test) that combines the technology and experience of people in identifying foreseeable failure modes of a product or process and planning for its elimination. In other words FMEA can be explained as a group of activities intended to. Recognize and evaluate the potential failure of a product or process and its effects,

Identify actions that could eliminate or reduce the chance of potential failure

occurring, document the process. FMEA is a “before-the-event” action requiring a team effort to alleviate most easily and inexpensively changes in design and production. 3.8 QUALITY FUNCTION DEPLOYMENT (QFD) Quality function deployment (QFD) is a planning tool used to fulfill customer’s expectations. It is a disciplined approach to product design, engineering, and production and provides in depth evaluation of a product. An organization that correctly implements QFD can improve engineering knowledge, productivity, and quality and reduces cost, product development time and engineering changes.

Quality function deployment focuses on

customer’s expectation and requirements, often referred to as the voice of the customer. It is employed to translate customer expectations, in terms of specific requirements, into directions and actions, in terms of engineering characteristics, that can be deployed through Product planning, Part development, Process planning, Production planning and Service. Quality function is a team based management tool in which customer expectations are used to drive the product development process. Conflicting characteristic of requirements are identified early in the QFD process and can be resolved before production. Organizations today use market research to decide what to produce to satisfy customer requirement. Some customer’s requirement adversely affects others, and customer often cannot explain their expectations. Confusion and misinterpretation are also a problem while a product moves from marketing to design to engineering to manufacturing. This activity is where the voice of the customer becomes lost and the voice of the organization adversely enters the product design. Instead of working what the customer expects, work is concentrated on fixing what the customer does not want. Quality function deployment helps identify new quality technology and job functions to carry out operations. This tool provides a historic reference to enhance future technology and prevent design errors QFD is primarily a set of graphically oriented planning materials that are used as basis for decision affecting any phase of product development cycle. Results of QFD are measured based on the number of design and engineering changes, to market, cost, and quality.

It is considered by many experts to be a perfect blueprint for quality by

design. Quality Function Deployment enables the design phase to concentrate on the customer requirement, there by spending less time on redesign and modification. The saved time is estimated a one-third to one-half of the time taken for redesign and modification using traditional means. This saving means reduced development cost and also additional income because the product enters the market sooner. -6-

3.8.a LITERATURE SURVEY ONE QFD In 1986, the ford and rank Xerox Company has introduced QFD in the western world while it was famously referred as quality tables in Japan since 1972. Chang (1989) has discussed the importance of using QFD to become competitive in the market. The QFD have changed dramatically from providing defect free products to customer driven or desired products. Denton (1990) has elaborately discussed the use of QFD to enhance competitiveness and customer satisfaction. Maddux (1991) has analyzed the QFD as a strategic planning tool in organization. Hales (1994) has attempted to stress the need for using QFD as a powerful tool to implement simultaneous engineering philosophy. Herzwurm and Schockert (2003) have presented the state-of the are of QFD in software development. 3.8.b BENEFITS OF QFD 1. Customer Driven ·

Creates focus on customer requirements.

·

3.8.c THE VOICE OF THE CUSTOMER Because QFD concentrates on

customer expectation and needs, a considerable

amount of effort is put in to research to determine costumer expectations. Words used by customer to describe their expectations are often refereed to as the voice of the customer. Sources for

determining customer expectation are focus group, surveys, complaints,

consultants, standards, and federal regulations. Quality function deployment begins with what exactly the customer desire from a product. During the collection of information, the QFD team must continually ask and answer numerous questions, such as What does the customer really want? Are the customer expectation used to drive the design process? What can the design team do to achieve customer satisfaction?

3.8.d HOUSE OF QUALITY The primary planning tool used in QFD is the house of quality. The house of quality translates the voice of the customers into design requirements that meet specific target values and matches those against how organizations will meet those requirements. Many managers and engineers consider the house of quality to be the primary chart in quality planning. The structure of QFD can be though of as a frame work of a house, as shown in figure.

4. CONCLUSION From the above discussion. It can be concluded that: “ Quality is not achieved by doing different things.

If is achieved by doing things

differently”. Total quality management implies an organizational obsession that will meet or exceed customer expectations to the point that are delighted. Understanding the customer’s needs and expectations is essential for wining new business and keeping the existing business. To attain this level, the organization continually needs to examine the quality system to see that it is responsive to ever changing customer requirements and expectations. The most successful TQM program finds its basis in clearly defining quality viewed from the customer’s perspective. The tool to fulfill customer’s expectations is Quality Function Deployment. Hence it is clear that QFD is an effective tool for TOTAL QUALITY MANAGEMENT.
