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.
