ShewhartCycle

Last edit August 11, 2004
WalterShewhart's adaptation of the ScientificMethod to manufacturing process improvement (the ShewhartCycle) was Plan, Do, Study, Act.

  • Plan the change you intend to make
  • Make the change
  • Study the effect(s) of the change
  • Act on the study

Often depicted as a circle divided into quadrants with the letters P, D, S, and A clockwise from the first quadrant, the idea is to encourage a continuing search for changes that would improve a process.
