Which description best captures Plan-Do-Check-Act (PDCA)?

• A. A cycle for continuous improvement
• B. A statistical test for variance
• C. A project management method for resource allocation
• D. A data collection method

Answer: (A)

PDCA is a cycle for continuous improvement. It frames improvement as an ongoing loop: Plan what change to make and how to measure success, Do the change on a small scale to test it, Check the results to see whether the outcomes matched the expectations, and Act based on what was learned—standardizing the successful change or starting another cycle to address remaining gaps. This iterative process promotes learning, gradual refinement, and sustained gains over time. It isn’t a statistical test for variance, nor a project management method for allocating resources, nor a data collection method; those describe different approaches with different primary goals.
