In the PDSA improvement model, which step involves testing the change?

• A. Plan
• B. Do
• C. Study
• D. Act

Answer: (B)

Testing the change occurs in the Do phase. After planning what you will test and how you’ll measure its impact, you implement the change on a small scale to observe how it works in practice and to collect data on its effects. This hands-on execution is what distinguishes Do from the other steps: Plan sets up the test, Study analyzes the collected results, and Act decides next steps based on what was learned. So, the step that involves testing the change is the Do phase.
