解説
問 40
Incorrectア
Estimating the cost and securing the necessary budget is an activity of project cost management. It is estimating and managing money within a single area, not coordinating trade-offs across areas, so it does not qualify as integration management.
- イ
正解 The essence of integration management is coordinating trade-offs between competing objectives and alternatives and determining resource allocation across multiple management areas. When you add a function that was not in the original plan, a dilemma arises: keeping the delivery deadline requires more personnel (cost), while not adding personnel pushes the deadline back. Choice イ, considering whether to change the delivery deadline or add personnel, is exactly the act of weighing these competing alternatives to achieve an overall optimum, which matches the definition given in the stem. Therefore イ is the appropriate activity of integration management.
Incorrectウ
Clarifying the necessary work and deliverables and updating the WBS (Work Breakdown Structure) is an activity of project scope management. It is defining and breaking down the scope of work, not coordinating between alternatives, so it is not integration management.
Incorrectエ
Estimating the required duration and changing the schedule is an activity of project schedule management. It is work confined to time-axis planning, not coordinating competing objectives, so it does not fall under integration management.
ここがポイント
- Project integration management is the activity of determining resource allocation and coordinating trade-offs between competing objectives and alternatives across areas such as cost, scope, and schedule.
- The key is to identify which management area each choice belongs to. It is not the within-a-single-area estimating or updating (cost = ア, scope = ウ, schedule = エ), but choice イ, which weighs alternatives across areas, that counts as integration management.
