In the Plan-Do-Study-Act cycle, which phase involves implementing changes and testing them?

• A. Plan
• B. Do
• C. Study
• D. Act

Answer: (B)

During the Do phase, you implement the planned changes and test them in practice. After designing the change, this step puts it into action—often as a small pilot—while you carry out the tasks, train staff, and monitor how the change works in the real environment. The goal is to observe actual performance and gather data on outcomes, so you can see whether the change produces the expected improvement or if adjustments are needed. The other phases have different roles: Plan is about designing the change and outlining how it will be tested; Study involves analyzing the collected data to determine effectiveness; Act means deciding whether to adopt, modify, or abandon the change and then standardize successful practices. For example, you might roll out a new hand hygiene reminder in one unit, collect compliance and infection data, and decide based on those results whether to expand the change.
