Performance Excellence And Our Covid-19 Global Leadership Crisis: What Would Deming, Juran And Crosby Say Today?
By Dale F. Weeks

Excerpt From The Certified Manager of Quality/Organizational Excellence Handbook

Walter A. Shewhart. Shewhart is referred to as the father of statistical quality control because he brought together the disciplines of statistics, engineering, and economics. Shewhart worked at Bell Laboratories, who pioneered the quality discipline and gave the profession some of its most capable experts. A mentor of both Juran and Deming, Shewhart did extensive research in statistics and probability. He described the basic principles of the new discipline in his book Economic Control of Quality of Manufactured Product, the first statistics text focused on quality.

In his book he first proposed that there are two types of variation in a process—chance causes and assignable causes—and pointed out that assignable causes can be searched out and removed. He then presented a theory of charting data from the process, using statistically based control limits as a means of differentiating between the two types of causes. The use of lot-by-lot inspection and understanding the relationship between process variation and specifications were also spelled out. Shewhart’s focus was on finding economic ways to reduce costs by identifying problems sooner in the process and by reducing the cost of inspection. See Chapter 15 for more on statistical techniques.

Shewhart created the concept of plan–do–check–act, which Deming later adapted.

W. Edwards Deming. Deming saw quality as the primary driver for business and societal success, and communicated the philosophy as a chain reaction. The premise is that if one improves quality, then costs will be lowered and resources better utilized. This increase in productivity will then allow the company to capture market share due to both higher quality and lower price, which will allow the organization to stay in business and to provide more jobs (known as the Deming chain reaction).

Deming’s best known contribution was his 14 points for transformation of Western management:

  1. Create constancy of purpose for improving products and services.
  2. Adopt the new philosophy.
  3. Cease dependence on inspection to achieve quality.
  4. End the practice of awarding business on price alone; instead, minimize total cost by working with a single supplier.
  5. Improve constantly and forever every process for planning, production, and service.
  6. Institute training on the job.
  7. Adopt and institute leadership.
  8. Drive out fear.
  9. Break down barriers between staff areas.
  10. Eliminate slogans, exhortations, and targets for the workforce.
  11. Eliminate numerical quotas for the workforce.11b. Eliminate numerical goals for management.
  12. Remove barriers that rob people of pride of workmanship, and eliminate the annual rating or merit system.
  13. Institute a vigorous program of education and self-improvement for everyone.
  14. Put everybody in the company to work accomplishing the transformation.
