解説
問 34
- ア
正解 In project management, the basic constraints that bind a project are three: scope, deadline (time), and budget (cost). Together they are called the triple constraint. The three are interrelated and form trade-offs: for example, widening the scope pushes the deadline back and raises the budget, while shortening the deadline forces you either to add people (raising the budget) or to cut the scope. A project manager plans and tracks progress while balancing these three. Therefore ア, which contains all three, is the correct choice.
Incorrectイ
Scope and deadline are indeed constraints, but the budget is missing. Risk, put in its place, is an uncertain event that threatens the achievement of project goals; it is the subject of risk management and is not part of the triple constraint.
Incorrectウ
Scope and budget are indeed constraints, but the deadline is missing. Because a project is temporary (it has a defined start and end), the deadline is a basic constraint that must always be considered, so a combination that omits it is inappropriate.
Incorrectエ
Deadline and budget are indeed constraints, but the scope is missing. Unless you decide what is to be built and how far, that is the scope, you cannot estimate either the deadline or the budget, so a combination that omits scope does not hold.
ここがポイント
- The triple constraint = scope, deadline (time), and budget (cost). A project manager manages by balancing these three.
- Risk is not a constraint; it is the uncertainty that is identified, analyzed, and responded to in risk management. Do not confuse it with the triple constraint.
