Example multiple-choice question and answer

C) Analyze. Explanation: Analyze is a DMAIC phase, not a PDCA stage. The four stages are Plan, Do, Check, Act.

Following the plan is the stage. This is the execution phase, but with a caveat: changes are typically implemented on a small or "pilot" scale. This mini-experiment allows the team to observe the plan in action without risking the entire operation. It is a period of active data collection where unexpected variables are documented. This hands-on testing provides the empirical evidence necessary for the next phase of the cycle.

The correct answer for stages that are part of the PDCA cycle depends on the specific options provided in your source material, but commonly cited "incorrect" stages include Analyze, Stream, and Define . Overview of PDCA Stages

Analyze and Improve (or any stages other than Plan, Do, Check, Act) are not stages of the PDCA cycle.

While analysis happens during the phase, "Analyze" is not a standalone stage in PDCA. It is, however, the third stage of the DMAIC (Define, Measure, Analyze, Improve, Control) framework used in Six Sigma. 2. "Review"

The PDCA cycle (Plan-Do-Check-Act) is a four-stage iterative process for continuous improvement.
