Describe the Plan-Do-Check-Act (PDCA) cycle and its role in quality improvement.

• A. PDCA is Plan-Do-Check-Act; used for project closing.
• B. PDCA is Plan-Do-Check-Act; used only for initial planning.
• C. PDCA is Plan-Do-Check-Act; used for continuous improvement by planning changes, implementing, measuring results, and adjusting.
• D. Prepare-Do-Complete-Approve; used for risk assessment.

Answer: (C)

Plan-Do-Check-Act is a simple, repeatable framework for continuous improvement. In quality work, it treats changes as small experiments and uses data to learn and iterate, rather than making big, untested shifts. Plan: define the problem or opportunity, set a clear objective, decide what change to test, and determine how you will measure success. You outline the expected outcome and the data you’ll collect to prove whether the change works. Do: implement the change on a small scale or pilot, while gathering data on its impact. This keeps risk low and provides a real test of the plan. Check: analyze the collected data, compare results to your predictions, and assess whether the change delivered the intended improvement. This step asks, what happened, why, and what the data show. Act: if the change proved beneficial, implement it more broadly and standardize it; if not, adjust the plan or revert, and begin a new cycle with revised ideas. The cycle then repeats, driving ongoing, evidence-based improvements. This approach is foundational in quality improvement because it emphasizes learning from results, making data-driven decisions, and continuously refining processes rather than executing one-off fixes.
