====PDCA myth====
It is a common myth to credit Plan-Do-Check-Act ([[PDCA]]) to Deming. Deming always referred to the Cycle as the [[Walter A. Shewhart|Shewhart]] Cycle for Continuous Learning and Improvement.<ref>{{Cite web|last=Deming|title=PDSA Cycle – The W.

In the article on "Clearing up myths about the Deming cycle and seeing how it keeps evolving", by Ron Moen and Clifford Norman, they refer to the first origins of PDCA in the work of [[Galileo Galilei|Galileo]] on Designed Experiments and [[Francis Bacon]]'s work on Inductive learning. The basic idea of Scientific method being – making a hypothesis, conducting experiment, learning about hypothesis through experiment results. Later the idea seems to have inspired [[C. I. Lewis|C I Lewis]] and through him to [[Walter A. Shewhart|Shewhart]], giving a clear account of evolution period from 17th century.<ref>{{Cite web|last=Deming|title=The History and Evolution of the PDSA Cycle – The W.

Deming credits a 1939 work by [[Walter A. Shewhart|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.&nbsp;132.<ref>{{cite journal |last1=Pruitt |first1=W. Frazier |last2=Imam |first2=S.M.
