解説
問 49
- ア
正解 The PDCA cycle turns in the order Plan → Do → Check → Act. The question states that the action plan was drawn up first, which corresponds to Plan. Therefore the subsequent activities a, b, and c follow the order Do → Check → Act. Item a (carry out risk countermeasures according to the action plan) is the Do that executes the plan; item b (measure the effect of the implementation and evaluate the effectiveness) is the Check that inspects the results; item c (implement corrective and improvement measures) is the Act that takes action based on the evaluation. Thus the order is a → b → c, and the correct answer is choice ア.
Incorrectイ
This is the order a (Do) → c (Act) → b (Check), performing correction and improvement (Act) before evaluation (Check). Improvement measures cannot be decided while the effect has not yet been measured and evaluated, so this violates the PDCA order.
Incorrectウ
This is the order c (Act) → a (Do) → b (Check), starting from correction and improvement (Act) before either execution (Do) or evaluation (Check) has taken place. Improvement should be based on evaluation results, so it can never come first.
Incorrectエ
This is the order c (Act) → b (Check) → a (Do), running the PDCA cycle completely in reverse. The sequence of improvement, evaluation, and execution reverses the cause-and-effect relationship and cannot function as a cycle.
ここがポイント
- The PDCA cycle turns in the order Plan → Do → Check → Act and is a management method that leads to continual improvement.
- Identify which phase each activity belongs to: carrying out countermeasures = Do, measuring the effect and evaluating effectiveness = Check, corrective and improvement measures = Act. Note that drawing up the plan (Plan) has already been completed.
