PDCA model

A repetitive four-step model for continuous improvement (CI) in business process management. The four steps are plan, do, check, and act/adjust.

Plan: Define the problem to be addressed, collect relevant data, and ascertain the problem's root cause.

Do: Develop and implement a solution; decide upon a measurement to gauge its effectiveness.

Check: Confirm the results through before-and-after data comparison.

Act/Adjust: Document the results, inform others about process changes, and make recommendations for the issue/problem to be addressed in the next PDCA cycle.

The model is used by teams in organizations to improve the quality and effectiveness of processes.

The PDCA model is also known as the Deming circle/cycle/wheel, Shewhart cycle, control circle/cycle, or plan–do–study–act (PDSA).
