Shewhart created the basis for the control chart and the concept of a state of statistical control by carefully designed experiments.

When determining which of the latest techniques or innovations to adopt, there are four major ...
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]
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.
This is also known as the Shewhart cycle, Deming cycle, or PDCA. Another technique used in conjunction with PDCA is the five whys, which is a form of root cause analysis in which the user asks a series of five "why" questions about a failure that has occurred, basing each subsequent question on the answer to the previous.
The recommendation was to adopt the teachings of W. Edwards Deming. [3] [4] The Navy branded the effort "Total Quality Management" in 1985. [3] [Note 1] From the Navy, TQM spread throughout the US Federal Government, resulting in the following: The creation of the Malcolm Baldrige National Quality Award in August 1987
