解説
問 45
Incorrectア
Accepting the request and securing budget and staff without evaluating the impact skips the change management procedure. Committing resources without considering the ripple effects on schedule and quality could cause the project to collapse, so it is not appropriate.
Incorrectイ
Mechanically declining on the blanket grounds that half the schedule has elapsed is mistaken. Whether a change is acceptable should be judged by evaluating its degree of impact, not merely by the elapsed time; rejecting a legitimate change request without examining it is inappropriate.
- ウ
正解 A feature addition introduced partway through development is a “change request.” What the project manager should do first is to weigh the impact of the change on cost, schedule, quality, staff, and so on, and to formally evaluate and decide on it according to the change management procedure established in advance. ウ follows this principle exactly and is the most appropriate. Neither accepting nor rejecting it unconditionally, but making the decision after an impact analysis, is the standard approach, so ウ is the correct answer.
Incorrectエ
A feature addition ripples not only to scope but also to cost, schedule, quality, and so on. Assuming without weighing the impact that it “affects only the scope” and promptly updating the baseline lacks the change management evaluation procedure and is inappropriate.
ここがポイント
- A change request should not be accepted or rejected unconditionally; evaluate its impact on cost, schedule, quality, and so on, and make a formal decision following change management (the change management procedure).
- Because a feature addition ripples across multiple constraints, not just scope, the scope baseline should be updated only after impact analysis and approval.
