Plan-Do-Check-Act (PDCA) is best described as which?

• A. A project governance model
• B. An improvement process
• C. A risk assessment tool
• D. A personnel evaluation method

Answer: (B)

PDCA is a cycle designed for continuous improvement of processes. In the Plan step you identify an aim, predict what will happen, and plan changes to test that hypothesis. In the Do step you carry out the change on a small scale and collect data. In the Check step you compare the outcomes with your predictions to see if the change produced the expected improvement and note any differences. In the Act step you decide to adopt the change, modify it, or abandon it, then begin the cycle again to refine the process. This is an improvement process because it explicitly links planning, implementation, evaluation, and adjustment in an ongoing loop, driving small, measurable gains and ultimately standardizing effective practices. It is not primarily a project governance model, which would focus on decision rights and oversight; it is not a risk assessment tool, which identifies hazards and estimates risk; and it is not a personnel evaluation method, which focuses on individual performance. In EMS, PDCA might be used to test a new field triage protocol, measure patient outcomes and transport times, and then revise the protocol based on data before broader adoption.
