Plan: — Define the problem, analyze the current state, identify root causes, develop a hypothesis, design an experiment, and set success criteria.
2
Do: — Implement the planned change on a small scale, document the process, and collect data.
3
Check: — Measure the results against the success criteria, compare to the baseline, and analyze the data.
4
Act: — Standardize the change if successful, adjust the plan if unsuccessful, or standardize what worked and plan the next cycle for remaining issues if partially successful.
5. Iterate through the PDCA cycle until the desired improvement is achieved or a new approach is needed.
