Deming credits a 1939 work by Shewhart for the idea and over time eventually developed the Plan-Do-Study-Act (PDSA) cycle, which has the idea of deductive and inductive learning built into the learning and improvement cycle. Deming finally published the PDSA cycle in 1993, in The New Economics on p. 132. [39]
Shewhart created the basis for the control chart and the concept of a state of statistical control by carefully designed experiments. While Dr. Shewhart drew from pure mathematical statistical theories, he understood data from physical processes never produce a " normal distribution curve" (a Gaussian distribution, also commonly called a "bell ...
The plan–do–check–act cycle is an example of a continual improvement process. The PDCA (plan, do, check, act) or (plan, do, check, adjust) cycle supports continuous improvement and kaizen. It provides a process for improvement which can be used since the early design (planning) stage of any process, system, product or service.
