PDCA​ Problem Solving

Plan

Recognize an opportunity and plan a change.

Do

Test the change. Carry out a small-scale study.

Check

Review the test, analyze the results, and identify what you’ve learned.​

Act

Take action based on what you learned in the study step. If the change did not work, go through the cycle again with a different plan. If you were successful, incorporate what you learned from the test into wider changes. Use what you learned to plan new improvements, beginning the cycle again.​
