Crosby, Philip B. (1999). Quality and Me: Lessons from an Evolving Life. San Francisco: Jossey-Bass. p. 159. OCLC 40444566. Quality is measured by the price of nonconformance, not by indexes.
Crosby, Philip B. (1996). Quality Is Still Free: Making Quality Certain in Uncertain Times. New York: McGraw-Hill. p. xiv. OCLC 32820340. The nonconformance situation semiconductor suppliers found recently emerged from embracing the standard of "Six Sigma." This permits 3.4 defects per million components. Why anyone would want to do that is beyond me. But they are now paying the price. When even ordinary chips contain a million or more components, such a standard means that they are all defective.
