From the perspective of total quality, who or what is to blame for adversarial management-labor rela- tions is irrelevant. What is important is this: To apply the total quality approach, organizations must have unity of purpose. This means that internal politics have no place in a total quality organization. Rather, collaboration should be the norm. A question frequently asked concerning this element of total quality is "Does unity of purpose mean that unions will no longer be needed?" The answer is that unity of purpose has nothing to do with whether unions are needed. Collective bar- gaining is about wages, benefits, and working conditions, not about corporate purpose and vision. Employees should feel more involved and empowered in a total quality setting than in a traditionally managed situation, but the goal of total quality is to enhance competitiveness, not to eliminate unions. For exam- TOTAL QUALITY PIONEERS By the late 1940s, key industrial leaders in Japan had finally come to the realization that the key to competing in the international marketplace is quality. At this time, Shigeiti Mariguti of Tokyo University, Sizaturo Mishibori of Toshiba, and several other Japanese leaders invited Deming to visit Japan and share his views on quality. Unlike their counter- parts in the United States, the Japanese industrialists accepted Deming's views, learned his techniques, and adopted his phi- losophy. So powerful was Deming's impact on industry in Japan that the most coveted award a company there can win is the Deming Prıze. In fact, the standards that must be met to win this prize are so difficult and so strenuously applied that it is now being questioned by some Japanese companies. By the 1980s, leading industrialists in the United States were where their Japanese counterparts had been in the late 1940s. At last, Deming's services began to be requested in his own country. By this time, Deming was over 80 years old. He had not been received as openly and warmly in the United States as he was in Japan. Deming's attitude toward corporate Total quality is not just one individual concept. It is a number of related concepts pulled together to create a comprehen- sive approach to doing business. Many people contributed in meaningful ways to the development of the various concepts that are known collectively as total quality. The three major contributors are W. Edwards Deming, Joseph M. Juran, and Philip B. Crosby. To these three, many would add Armand V. Feigenbaum and a number of Japanese experts, such as Shigeo Shingo. Plan Analyze The Neming Cycle Deming's Contributions Of the various quality pioneers in the United States, the best known is W. Edwards Deming. Deming's contribution was ple, in Japan, where companses are known for achieving unity of his ability to see the big picture, envision the impact of qual- ity on it, and meld different management philosophies into a new, workable, unitary whole. More than any other quality pioneer, Deming is responsible for the total quality approach. Deming came a lung way to acliieve ile status uf inter- nationally acclaimed quality expert During his formative years, Deming's family bounced from small town to small town in Iowa and Wynming, trying in vain to rise out of pow- erty. These early circumstances gave Deming a lifelong ap- preciation for economy and thrift. In later years, even after he was generating a substantial income, Deming maintained only a simple office in the basement of his modest home out of which he conducted his international consulting business. Working as a janitor and at other odd jobs, Deming worked his way through the University of Wyoming, where he earned a bachelor's degree in engineering. He went on to receive a master's degree in mathematics and physics from the University of Colorado and a doctorate in physics from Yale. His only full-time employment for a corporation was with Western Electric. Many feel that what he witnessed dur- ing his employment there had a major impact on the direction the rest of his life would take. Deming was disturbed by the 3 Check Act purpose, unions are still very much in evidence.

Deming's contributions to the quality movement would be difficult to overstate. Many consider him the founder of the movement. The things for which he is most widely known are the Deming Cycle, his Fourteen Points, and his Seven Deadly Diseases." 3. Check the product to make sure it was produced in ac- cordance with the plan (check). Employee Involvement and Empowerment 4. Market the product (act). Employee involvement and empowerment is one of the most misunderstood elements of the total quality approach and one of the most misrepresented by its detractors. The basis for involving employees is twofold. First, it increases the likelihood of a good decision, a better plan, or a more ef- fective improvement by bringing more minds to bear on the situation-not just any minds but the minds of the people who are closest to the work in question. Second, it promotes ownership of decisions by involving the people who will have to implement them. Empowerment means not just involving people but also involving them in ways that give them a real voice. One of the ways this can be done is by structuring work that allows employees to make decisions concerning the improvement of work processes within well-specified parameters. Should a machinist be allowed to unilaterally drop a vendor if the vendor delivers substandard material? No. However, the ma- chinist should have an avenue for offering his or her input into the matter. 5. Analyze how the product is received in the marketplace in terms of quality, cost, and other criteria (analyze). The Deming Cycle Summarized in Figure 1.3, the Deming Cycle was developed to link the production of a product with consumer needs and focus the resources of all departments (re- search, design, production, marketing) in a cooperative effort to meet those needs. The Deming Cycle proceeds as follows: Deming's Fourteen Points Deming's philosophy is both summarized and operationalized by his Fourteen Points, which are contained in Figure 1.4. Deming modified the specific wording of various points over the years, which ac- counts for the minor differences among the Fourteen Points as described in various publications. Deming stated repeat- edly in his later years that if he had it all to do over again, he 1. Conduct consumer research and use it in planning the product (plan). 2. Produce the product (do). would leave off the numbers. amount of waste he saw at Western Electric's Hawthorne plant. It was there that he pioneered the use of statistics in quality. Although Deming was asked in 1940 to help the U.S. Bureau of the Census adopt statistical sampling techniques, his reception in the United States during these early years was not positive. With hittle real competition in the interna- tional marketplace, major U.S. corporations felt little need for his help. Corporations from other countries were equally uninterested. However, attitudes toward Deming's idea were changed by World War II. The need to rebuild after the dev- astation of World War II, particularly in bombed-out Japan, brought Deming's ideas on quality to the forefront. During World War II, almost all of Japan's industry went into the hısiness of producing war materials After the war, those firms had to convert to the production of con- sumer goods, and the conversion was not very successful. To have a market for their products, Japanese firms had to enter the international marketplace. This move put them in direct 1. Create constancy of purpose toward the improvement of products and services in order to become competitive, stay in business, and provide joba. 2. Adopt the new philosophy. Management must leam that it is a new economic age and awaken to the challenge, leam their responsibilities, and take on leadership for change. 3. Stop depending on inspection to achieve quality. Build in qualilty from the start. 4. Stop awarding contracts on the basis of low bids. 5. Improve continuously and forever the system of production and service, to improve quality and productivity, and thus constantly reduce costs. 6. Institute training on the job. 7. Institute leadership. The purpose of leadership should be to help people and technology work better. 8. Drive out fear so that everyone may work effectively. 9. Break down barriers between departments so that people can work as a team 10. Eliminate slogans, exhortations, and targets for the workforce. They create adversarial relationships. 11. Eliminate quotas and management by objectives. Substitute leadership. 12. Remove barriers that rob ermployees of their pride of workmanship. 13.

Having done so, her next step should be to show other machinists her innovation so that they might try it. Peak Performance When effectively practiced, total quality allows every aspect of an organization to operate at peak levels. This means that all personnel and processes are operating at their best. Peak performance is essential to organizations that operate in a global environment where competition is intense, constant, competition with companies from the other industrialized and unforgiving. countries of the world, and the Japanese firms did not fare well.

The traditional view of attempt to adopt the total quality approach. This is because they look at total quality as just another management innova- tion rather than as a whole new way of doing business that The total quality approach was defined in Figure 1.2. This requires an entirely new corporate culture. Too few organiza- into one. Taylor's scientific management did away with this by making planning the job of management and production the job of labor. To keep quality from falling through the quality saw employees as passive workers who followed or- cracks, it was necessary to create a separate quality depart- ment. Such departments had shaky beginnings, and just who was responsible for quality became a clouded issue. As the volume and complexity of manufacturing grew, quality became an increasingly difficult issue. Volume and complexity together gave birth to quality engineering in the 1920s and reliability engineering in the 1950s. Quality engi- neering, in turn, resulted in the use of statistical methods in the control of quality, which eventually led to the concepts of control charts and statistical process control, which are now fundamental aspects of the total quality approach. Reliability engineering emerged in the 1950s. It began a trend toward moving quality control away from the traditional after-the-fact approach and toward inserting it throughout the design and production processes. However, for the most part, total quality perspective: quality control in the 1950s and 1960s involved inspections . Productivity versus quality. The traditional view is KEY ELEMENTS OF TOTAL QUALITY ders given by supervisors and managers. It was their labor, not their brains, that was wanted.

The traditional view of quality expected one improve- ment per employee per year. Total quality organizations expect to make at least ten or more improvements per em- ployee per year. Organizations that think traditionally focus on short-term profits. The total quality approach focuses on long-term profits and continual improvement. The following statements summarize some of the major differences between the traditional view of quality and the In traditionally managed organizations, the best competitive efforts are often among departments within the organization. Internal competition tends to use energy that should be focused on improving quality and, in turn, external competitiveness. Strategically Based Total quality organizations have a comprehensive strategic Continual Process Improvement plan that contains at least the following elements: vision, mis- sion, broad objectives, and activities that must be completed to accomplish the broad objectives. The strategic plan of a total quality organization is designed to give it a sustainable competitive advantage in the marketplace. The competitive fundamental goal in a total quality setting-it is necessary to advantages of a total quality organization are geared toward continually improve systems. achieving world-leading quality and improving on it, con- tinually and forever. Products are developed and services delivered by people using processes within environments (systems). To continu- ally improve the quality of products or services-which is a that resulted in nothing more than cutting out bad parts. World War II had an impact on quality that is still being felt. In general, the effect was negative for the United States and positive for Japan. Because of the urgency to meet production schedules during the war, U.S. companies focused more on meeting delivery dates than on quality. This approach became a habit that carried over even after that productivity and quality are always in conflict. You cannot have both. The total quality view is that lasting productivity gains are made only as a result of quality improvements. . How quality is defined. The traditional view is that quality is defined solely as meeting customer specifica- tions. The total quality view is that quality means satisfy- ing customer needs and exceeding customer expectations. Education and Training Education and training are fundamental to total quality be- cause they represent the best way to improve people on a con- tinual basis. It is through education and training that pcople who know how to work hard learn how to also work smart. Customer Focus In a total quality setting, the customer is the driver. This point applies to both internal and external customers. External customers define the quality of the product or ser- vice delivered. Internal customers help define the quality of Freedom Through Control the people, processes, and environments associated with the products or services. the war.

At first, their attempts were un- successful, and "Made in Japan" remained synonymous with poor quality, as it had been before World War II. Around 1950, however, Japan decided to get serious about quality and establishing ways to produce quality products. Japanese manufacturers overcame a reputation for pro- ducing cheap, shabby products and developed a reputation as world leaders in the production of quality products. More than any other sıngle factor, it was the Japanese miracle- which was not a miracle at all but the result of a concerted quality is measured by establishing an acceptable level of nonconformance and measuring against that bench mark. The total quality view is that quality is measured by establishing high-performance benchmarks for customer satisfaction and then continually improving performance. . How quality is achieved. The traditional view is that quality is inspected into the product. The total quality view is that quality is determined by product and process design and achieved by effective control techniques. Involving and empowering employees is fundamental to total quality as a way to simultaneously bring more minds to bear on the decision-making process and increase the ownership employees feel about decisions that are made. Total qual- ity detractors sometimes mistakenly see employee involve- ment as a loss of management control, when in fact control is fundamental to total quality. The freedoms enjoyed in a total quality setting are actually the result of well-planned Obsession with Quality In a total quality organization, internal and external custom- ers define quality. With quality defined, the organization must then become obsessed with meeting or exceeding this definition. This means all personnel at all levels approach all aspects of the job from the perspective of "How can we do this better?" When an organization is obsessed with quality, "good enough" is never good enough. and well-carried-out controls. Controls such as scientific methodologies lead to freedom by empowering employees to solve problems within their scope of control. effort that took 20 years to really bear frult-that got the rest of the world to focus on quality. When Western companies finally realized that quality was the key factor in global com- petition, they responded. Unfortunately, their first responses were the opposite of what was needed. In spite of these early negative reactions, Western com- panies began to realize that the key to competing in the global marketplace was to improve quality. With this realization, the total quality movement finally began to gain momentum. Attitude toward defects. The traditional view is that defects are an expected part of producing a product. Measuring defects per hundred is an acceptable standard. The total quality view is that defects are to be prevented using effective control systems and should be measured in defects per million (Six Sigma). . Quality as a function. The traditional view is that quality is a separate function. The total quality view is that quality should be fully integrated throughout the organization-it should be everybody's responsibility. . Responsibility for quality. The traditional view is that employees are blamed for poor quality. The total quality view is that at least 85% of quality problems are manage- Scientific Approach Unity of Purpose Total quality detractors put off by such concepts as employee Historically, management and labor have had an adversarial empowerment sometimes view total quality as nothing more than another name for "soft" management or "people" man- agement. Although it is true that people skills, involvement, and empowerment are important in a total quality setting, they represent only a part of the equation. Another important part is the use of the scientific approach in structuring work and in making decisions and solving problems that relate to the work. This means that hard data are used in establishing bench marks, monitoring performance, and making improvements relationship in U.S. industry.
