解説
問 43
Incorrectア
Event a is correct, but b is wrong. Event b, “replacement of the assigned systems engineer,” merely swaps the person in charge (a human resource); neither the range of work to be carried out nor the range of deliverables changes, so it does not affect the project scope. Including b makes this option inappropriate.
- イ
正解 As defined in the question, the project scope refers to “the range of the project's work.” Only changes that increase or decrease the amount of work (what has to be done) affect the project scope. Event a, “addition of functional requirements to be developed,” adds new functions that must be developed, so the development work grows and the work range—that is, the project scope—is affected. Event c, “addition of an operation manual to be documented,” also increases the documents that must be produced, so the documentation work grows and the project scope is affected. Therefore the affected events are a and c, and the correct answer is “イ (a, c).”
Incorrectウ
This option lists only b, but b is a change of personnel and does not affect the project scope (work range). Moreover, it omits a and c, which increase the work and do have an effect, so it is wrong on two counts.
Incorrectエ
Event c is correct, but b is wrong. Event b is a replacement of personnel and does not change the work range, so it does not affect the scope. It also fails to include a, which increases the work, so it is deficient and inappropriate.
ここがポイント
- The two categories of scope—product scope (the range of deliverables) and project scope (the range of work). The question is about telling which of these two ranges a change affects.
- Changes that increase or decrease the amount of work (adding functions, adding documents) affect the project scope, whereas replacing the person in charge is merely a change of human resources and does not affect the scope (work range or deliverable range).
