The Plan-Do-Check-Act (PDCA) cycle is a four-step model for carrying out positive change in repetitive, goal-oriented activities.
Recognize an improvement opportunity and plan a change, usually in a process and/or a tool.
Try out the planned improvement, at least on a small scale, and see how it works.
Review the results of the initial trial implementation, and identify lessons learned, determining what worked as planned and what didn’t.
Based on the results reviewed, take appropriate action to implement the improvement on a more ongoing basis, with possible adjustments based on lessons learned from the Do and Check steps.
