What does PDCA stand for?

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

Answer: (C)

PDCA is a four-step, iterative approach for improving processes. It begins with Plan, where you set objectives, study the current process, identify what to change, and decide how to test the change. Then Do involves implementing the plan on a small scale to collect data. Next, Check is about analyzing the results and comparing them to what you expected to learn whether the change helped. Finally, Act means deciding what to do next—standardize successful changes, adjust what didn’t work, or start another cycle to drive further improvement. This order creates a feedback loop where learning from the test leads to informed action. The standard sequence is Plan-Do-Check-Act because checking results before acting ensures you only implement changes that have been verified to be beneficial. The other orderings disrupt the logic of testing and learning before committing to action, and thus do not align with how PDCA is intended to function.
