解説
問 50
Incorrectア
Setting acceptable control limits (upper and lower) and detecting events that deviate beyond them is a monitoring/control technique using tools such as control charts. It belongs to the later “control” step, not the “identification” step of newly surfacing risks, so it is incorrect.
Incorrectイ
A decision tree diagram (decision tree) is an analysis technique that calculates the probability of occurrence and expected value of each option to support decision-making. It is used at the stage of quantitatively analyzing risks that have already been grasped, not as a technique for the “identification” step of enumerating risks, so it is incorrect.
Incorrectウ
A matrix of probability of occurrence and degree of impact is a technique for evaluating already-surfaced risks by their probability and magnitude of impact and prioritizing them. This corresponds to the “analysis and evaluation” stage carried out after “identification,” so it is incorrect as a method for surfacing risks.
- エ
正解 Risk identification (surfacing risks) is the stage of exhaustively enumerating the risks that are likely to affect the project. Choice “エ,” conducting brainstorming with the stakeholders gathered together, lets participants freely exchange opinions and thereby surface potential risks broadly from diverse viewpoints; it is a representative risk-identification technique and the most appropriate method for this stage.
ここがポイント
- Risk management proceeds in the flow of “identification (surfacing) → analysis and evaluation → control,” and the technique used at each stage differs.
- In risk identification (surfacing), techniques that broadly gather opinions from stakeholders, such as brainstorming, are effective. Matrices and decision trees are techniques for analysis and evaluation.
