| Inspired by the "Shewhart Cycle", W. Edwards Deming created his own "Deming Cycle", which he introduced in 1950 at a [[http://juse.or.jp/english/|"Japanese Union of Scientists and Engineers" (JUSE)]] sponsored eight-day seminar on statistical quality control for managers and engineers. His straight-line: Step 1- "Design", Step 2 – "Produce", Step 3 - "Sell" was converted to a circle with a fourth step added: Step 4 - "Redesign through marketing research". | Inspired by the "Shewhart Cycle", W.
