Which quality-improvement cycle is described as Plan-Do-Study-Act?

• A. PDCA cycle
• B. Plan-Do-Study-Act (PDSA) cycle
• C. Six Sigma
• D. Root Cause Analysis

Answer: (B)

Plan-Do-Study-Act is a quality-improvement cycle that emphasizes testing changes on a small scale, learning from the results, and using that learning to guide next steps. In plan, you set a clear aim, predict what will happen, and outline how you’ll implement the change. In do, you carry out the change. In study, you measure and analyze the outcomes to see if the results matched your predictions. In act, you decide whether to adopt the change, modify it, or abandon it, then begin another cycle if needed. This focus on measuring outcomes and using data to inform the next steps is why it’s described as Plan-Do-Study-Act.
