解説
問 53
Incorrectア
Project Cost Management is the activity responsible for estimating costs, budgeting, and controlling costs. In this question cost is one of the decision factors, but the goal is not to manage cost alone; rather it is to combine multiple factors including staff count and days to select a plan comprehensively, so it does not fit this activity that deals only with cost.
Incorrectイ
Project Human Resource Management is the activity responsible for forming, developing, and managing the project team. In this question staff count is among the decision factors, but what is being done is not developing or managing the team; it is a trade-off decision that spans staff, cost, and days, so it does not apply.
Incorrectウ
Project Time Management is the activity responsible for defining and sequencing work, estimating durations, and creating and controlling the schedule. Shortening the schedule is indeed the goal in this question, but the actual decision is a cross-cutting one that combines days, staff, and cost to choose the overall optimum, so it does not fit within this activity that deals only with time.
- エ
正解 The correct answer is エ, “Project Integration Management.” Integration management is the activity of coordinating requirements that span multiple knowledge areas — such as time, cost, and staffing (human resources) — and choosing the best plan by balancing competing objectives. In this question, plans that combine the number of staff that can be assigned, the cost required to assign them, and the number of days that can be shortened are compared; from among the plans that achieve the schedule reduction, the one that minimizes both the staff count and the overall cost is selected. This is exactly the act of coordinating trade-offs across multiple areas to make an integrated, comprehensive decision, which corresponds to integration management.
ここがポイント
- Project Integration Management is the activity that coordinates multiple knowledge areas such as time, cost, and human resources, makes trade-offs among competing objectives, and thereby makes integrated decisions and selects the optimal plan.
- A description of “combining multiple constraint factors, comparing them, and choosing the overall optimum” is a typical clue that points to integration management rather than to an individual area (cost / time / human resources).
