6 - 18 © 2014 Pearson Education, Inc. Takumi A Japanese character that symbolizes a broader dimension than quality, a deeper process than education, and a more perfect method than persistence
6 - 19 © 2014 Pearson Education, Inc. Leaders in Quality TABLE 6.1 Leaders in the Field of Quality Management LEADER PHILOSOPHY/CONTRIBUTION W. Edwards Deming Deming insisted management accept responsibility for building good systems. The employee cannot produce products that on average exceed the quality of what the process is capable of producing. His 14 points for implementing quality improvement are presented in this chapter. Joseph M. Juran A pioneer in teaching the Japanese how to improve quality, Juran believed strongly in top-management commitment, support, and involvement in the quality effort. He was also a believer in teams that continually seek to raise quality standards. Juran varies from Deming somewhat in focusing on the customer and defining quality as fitness for use, not necessarily the written specifications.
6 - 20 © 2014 Pearson Education, Inc. Leaders in Quality TABLE 6.1 Leaders in the Field of Quality Management LEADER PHILOSOPHY/CONTRIBUTION Amarnd Feigenbaum His 1961 book Total Quality Control laid out 40 steps to quality improvement processes. He viewed quality not as a set of tools but as a total field that integrated the processes of a company. His work in how people learn from each other’s successes led to the field of cross-functional teamwork. Philip B. Crosby Quality Is Free was Crosby’s attention-getting book published in 1979. Crosby believed that in the traditional trade-off between the cost of improving quality and the cost of poor quality, the cost of poor quality is understated. The cost of poor quality should include all of the things that are involved in not doing the job right the first time. Crosby coined the term zero defects and stated, “There is absolutely no reason for having errors or defects in any product or service.”

    6 - 19 ©2014 Pearson Education, Inc. Leaders in Quality TABLE 6.1 Leaders in the Field of Quality Management LEADER PHILOSOPHY/CONTRIBUTION W. Edwards Deming Deming insisted management accept responsibility for building good systems. The employee cannot produce products that on average exceed the quality of what the process is capable of producing. His 14 points for implementing quality improvement are presented in this chapter. Joseph M. Juran A pioneer in teaching the Japanese how to improve quality, Juran believed strongly in top-management commitment, support, and involvement in the quality effort. He was also a believer in teams that continually seek to raise quality standards. Juran varies from Deming somewhat in focusing on the customer and defining quality as fitness for use, not necessarily the written specifications.

    6 - 20 ©2014 Pearson Education, Inc. Leaders in Quality TABLE 6.1 Leaders in the Field of Quality Management LEADER PHILOSOPHY/CONTRIBUTION Amarnd Feigenbaum His 1961 book Total Quality Control laid out 40 steps to quality improvement processes. He viewed quality not as a set of tools but as a total field that integrated the processes of a company. His work in how people learn from each other’s successes led to the field of cross-functional teamwork. Philip B. Crosby Quality Is Free was Crosby’s attention-getting book published in 1979. Crosby believed that in the traditional trade-off between the cost of improving quality and the cost of poor quality, the cost of poor quality is understated. The cost of poor quality should include all of the things that are involved in not doing the job right the first time. Crosby coined the term zero defects and stated, “There is absolutely no reason for having errors or defects in any product or service.”
