Iterative management method for continuous improvement of processes by planning, doing, checking and acting.
The PDCA cycle (Plan–Do–Check–Act) is an iterative method for continuous process improvement and problem solving. Teams plan actions, execute them, inspect results, and adjust processes accordingly. The cycle promotes systematic learning loops, measurable improvements, and can be applied across quality management, operations, and service delivery contexts.
Measures the average time for a PDCA iteration until action.
Percentage reduction of relevant error or failure rates after actions.
Ratio of planned hypotheses to experiments actually tested.
Applying PDCA to reduce scrap rates through measurement, pilot actions and process adjustments.
Iterative measures to reduce incidents by targeted tests and gradual introduction of configuration changes.
Using PDCA to turn customer feedback into small experiments and measurable improvements.
1) Define: Set clear scope, target metrics and success criteria.
2) Plan: Formulate hypotheses and design a small pilot.
3) Do: Implement pilot measures in a controlled way and document.
4) Check: Evaluate results against metrics and assumptions.
5) Act: Adjust measures, document, and scale if successful.
