In the Plan-Do-Study-Act cycle, what does the 'Act' step involve?

• A. Implement or adjust and spread the change
• B. Plan a change
• C. Do to implement on a small scale
• D. Study results

Answer: (A)

Act involves taking what was learned in Study and deciding the next course of action. It includes implementing the change if results look good, adjusting the change based on data, and spreading successful modifications to other settings or populations. In this framework, Plan is about designing the change, Do is implementing it on a small scale, and Study is evaluating the outcomes; Act is where you decide to adopt, adapt, or abandon and plan the next cycle.
