The PDCA cycle is designed to be used as a dynamic model for the improvement of a process or system . The completion of one turn of the cycle flows into the beginning of the next. Following in the spirit of continuous quality improvement, the process can always be reanalyzed and a new test of change can begin. This continual cycle of change is represented in the ramp of improvement.

Plan - a change or a test, aimed at improvement.

Do - Carry out the change or test (preferably on a small scale).

Check - Implement the change you decided on in the plan phase.

Check or Study - the results. What was learned? What went wrong?

Act - Adopt the change, abandon it, or run through the cycle again.
