Deming is best known in the United States for his 14 Points (Out of the Crisis, by W. Edwards Deming, preface) and his system of thought he called the "System of Profound Knowledge". The system includes four components or "lenses" through which to view the world simultaneously: Appreciating a system; Understanding variation; Psychology
This common-cause variation is evident from the experience base. However, new, unanticipated, emergent or previously neglected phenomena (e.g. "new diseases") result in variation outside the historical experience base. Shewhart and Deming argued that such special-cause variation is fundamentally unpredictable in frequency of occurrence or in ...
Praised by Dr. W. Edwards Deming (the business guru of the 1980s American quality movement), [1] it made clear the concept that quality does not suddenly plummet when, for instance, a machinist exceeds a rigid blueprint tolerance. Instead 'loss' in value progressively increases as variation increases from the intended condition.
Walter Andrew Shewhart (pronounced like "shoe-heart"; March 18, 1891 – March 11, 1967) was an American physicist, engineer and statistician. He is sometimes also known as the grandfather of statistical quality control and also related to the Shewhart cycle.
Deming was an important architect of the quality control short courses that trained American industry in the new techniques during WWII. The graduates of these wartime courses formed a new professional society in 1945, the American Society for Quality Control, which elected Edwards as its first president. Deming travelled to Japan during the ...
The more information and knowledge (especially allowing the shaping of natural environment) a given society has, the more advanced it is. [70] He distinguishes four stages of human development, based on advances in the history of communication. [70] In the first stage, information is passed by genes. [70]
Exemplifying Differentiation and System Theory, this photographic mosaic may be perceived as a whole/system (a gull) or as a less complex group of parts.. Talcott Parsons was the first major theorist to develop a theory of society consisting of functionally defined sub-systems, which emerges from an evolutionary point of view through a cybernetic process of differentiation.
According to Deming, during his lectures in Japan in the early 1950s, the Japanese participants shortened the steps to the now traditional plan, do, check, act. [4] Deming preferred plan, do, study, act because "study" has connotations in English closer to Shewhart's intent than "check". [10]
