問 91
Incorrectア
The four risk treatments are options chosen according to the situation; they are not an implementation procedure that proceeds in a fixed order such as avoidance to transfer to reduction to retention. The premise is wrong.
Incorrectイ
As with ア, treating risk treatment as a fixed procedure of retention to reduction to transfer to avoidance is wrong. These are not an order but parallel options.
Incorrectウ
Taking out insurance in preparation for a risk materializing is risk transfer, in which the insurance company assumes the compensation for the loss; it is not risk avoidance (stopping the very activity that is the source of the risk).
- エ
正解 Risk transfer, avoidance, reduction, and retention are parallel options for responding to an identified risk. Managing the carrying of a laptop PC outside the company more strictly to prepare against its loss or theft is a measure that reduces the likelihood of occurrence and the size of the damage, so it falls under risk reduction. Therefore エ is appropriate.
- The four risk treatment methods (transfer, avoidance, reduction, retention) are not an implementation order but parallel options chosen for each individual risk.
- Grasp the distinctions: risk reduction = measures that lessen the likelihood or impact; risk transfer = having a third party bear the loss via insurance, etc.; risk avoidance = stopping the activity that is the source of the risk itself.
