Which option best describes the PDCA/PDSA framework?

• A. A framework for project budgeting and cost control.
• B. Iterative improvement in processes.
• C. A one-time process audit tool.
• D. A framework for epidemiologic modeling.

Answer: (B)

Iterative improvement in processes is what the PDCA/PDSA framework aims to achieve. It cycles through planning a change, trying it on a small scale, studying the results, and deciding whether to act to refine the change or implement it more broadly. This learning-by-doing loop lets teams test alterations, gather data, and adjust before a full rollout, which is especially valuable in public health where processes often need refinement to reduce disparities and improve outcomes. By continually cycling through these steps, teams can build evidence, learn what works in real-world settings, and steadily raise the quality of programs and services. This isn’t primarily about budgeting and cost control, it isn’t a one-time audit, and it isn’t a method for epidemiologic modeling.
