解説
問 44
- ア
正解 The procedure for a specification change (change management) starts with the receipt of the change request, where the help desk accepts a change request from a user or customer. Receiving it alone is not enough to carry it out, so the next step is the evaluation of the change content, which examines whether the change is technically feasible and how it affects effort, cost, delivery date, quality, and other functions. If the evaluation leads to a decision to implement it, an instruction of the change is issued to the developers, and finally the application of the change, in which the design documents and programs are actually modified, completes the procedure. A in the figure is the second of the four boxes from the left, that is, immediately after the receipt, so the matching item is ア, evaluation of the change content.
Incorrectイ
The instruction of the change is issued only after the evaluation has led to a decision to implement the change, so it is the third step. Issuing an instruction without evaluating would mean having the work done without knowing the scope of impact or the cost, which does not make sense as an order.
Incorrectウ
The application of the change is the work of actually modifying the design documents and programs after receiving the instruction, and it is the last (fourth) step. A in the figure is the second from the left, so it does not match.
Incorrectエ
The receipt of the change request is the starting point of the procedure, and in the figure it is the box just to the left of A. Because its position is first, it does not match A.
ここがポイント
- The basic procedure for a specification change (change management) has four stages: receipt of the change request, evaluation of the change content, instruction of the change, and application of the change. The key point is that evaluation and approval (the instruction) always come between receipt and implementation.
- In the evaluation of the change content, besides feasibility, the impact on effort, cost, delivery date, quality, and other parts is checked. Applying a change without evaluating it becomes a cause of rework such as cost overruns or lower quality.
