PDCA cycle in software testing

Plan (P): Devise a plan – Define your objective, determine the strategy and supporting methods required to achieve that objective.

Do (D): Execute the plan – Create necessary test condition and perform necessary training to execute the plan.

Check (C): Check the result, check to determine whether the work is progressing according to the plan and whether the results are obtained. Check for performance of the procedures, changes in conditions, or abnormalities that may appear.

Action (A): Take the necessary and appropriate action. If the check reveals that the work is not being performed according to plan, or if results are not what were anticipated, devise measures for appropriate action. Look for the cause of the abnormality to prevent its recurrence. Sometimes employees may need to be retrained and procedures revised. The next plan should reflect these changes and define them in more detail.
