In the Plan-Do-Study-Act cycle, which phase is responsible for measuring the results of the improvement effort?

• A. Plan
• B. Study
• C. Do
• D. Act

Answer: (B)

Measuring results and evaluating what happened is what the study phase focuses on in Plan-Do-Study-Act. After planning the change and implementing it on a small scale, the study phase collects and analyzes the data to see whether the improvement achieved the desired effect, comparing outcomes to the baseline and looking for patterns, unintended consequences, or additional learning. This is the step where you determine if the change worked well enough to adopt, modify, or abandon it. The planning phase defines what will be measured and how, the doing phase puts the plan into action, and the acting phase decides the next steps based on what was learned.
