What is PDCA?

What is PDCA?

• A. Plan-Do-Check-Act, an 8-step problem-solving model for continuous improvement.
• B. A cycle for software debugging.
• C. A project management method with five phases.
• D. A Lean manufacturing process with just-in-time.

Answer: (A)

PDCA is a four-step cycle used for continuous improvement of processes and products. It starts with Plan: set clear objectives, define what you’ll measure, and plan the actions needed to reach the target. Do: implement the plan on a small scale or pilot to test how it works in practice. Check: examine the results, compare them to what you expected, and learn from the outcome. Act: decide what to adjust, implement the improvements, and standardize successful changes so you can begin the cycle again and keep refining. The correct choice names the sequence Plan-Do-Check-Act and describes it as a cycle for ongoing improvement, which the PDCA framework embodies. The note about eight steps is not part of the standard PDCA model, since it is traditionally four steps. The other options describe concepts that don’t match this continuous-improvement cycle.
