What does the PDCA/PDSA Framework stand for?

• A. Plan-Do-Check-Act
• B. Plan-Do-Study-Act
• C. Plan-Check-Act-Do
• D. Plan-Do-Check-Act; Plan-Do-Study-Act

Answer: (D)

This framework is a continuous improvement loop. You plan what change to make, then do it on a small scale. After that you evaluate what happened—either calling this step Check or Study to see if the results align with the plan. Finally, you Act to adjust, iterate, or standardize what worked. Some teams use Check, others use Study for the evaluation step, but both describe the same cycle. The best answer shows both naming variants: Plan-Do-Check-Act; Plan-Do-Study-Act. It acknowledges the two common labels for the evaluate-andlearn phase while preserving the same four-step sequence. Other phrasings either change the order or only reflect one naming convention, which misses part of how the framework is commonly described.
