Which framework uses Plan, Do, Check, Act to implement changes?

• A. Continuous Improvement Outline
• B. Plan-Do-Check-Act Cycle
• C. Deming Cycle
• D. Lean Process

Answer: (A)

Plan-Do-Check-Act Cycle embodies the four steps used to implement and refine changes in a structured, iterative way. You start by planning the change—defining what you’ll do, how, who will be involved, and what success looks like. Then you implement on a small scale (do), measure the results against your expectations (check), and decide whether to adjust, standardize, or abandon the change (act). This loop repeats, driving continuous improvement.

The Deming Cycle is essentially the same idea, just another name for the same sequence, so you’ll sometimes see it referenced that way. Lean Process is a broader methodology focused on eliminating waste and improving flow, not the specific Plan-Do-Check-Act sequence. Continuous Improvement Outline isn’t a standard framework name.
