Plan
PDCA is the Continuous Process Improvement (CPI)
movements acronym for the steps in an
improvement project. The letters stand for Plan,
Do, Check, and Act. These verbs refer to the
activities required for a single improvement
project. Obviously, the first activity is
Planning. The next activity is executing the
plan, or Doing.

Do
The first activity is Planning. The next
activity is executing the plan or Doing. The next
activity is Checking to see if the execution
actually met the criteria of the plan. If so then
the project team moves on to the planning phase
of the next project.
