In the Plan-Do-Check-Act cycle, which step involves implementing the change?

• A. Do.
• B. Plan.
• C. Check.
• D. Act.

Answer: (A)

Implementing the change happens in the Do phase of the PDCA cycle. Plan is about defining the objective and outlining how to achieve it, including steps, resources, and metrics. Do puts that plan into action, carrying out the change and gathering data on its performance. Check then reviews the results against expectations, and Act decides what to do next—standardize the successful change or revise and restart the cycle. So the step that actually implements the change is Do.
