• ×Incorrectア

  The change control board is made up of people who have responsibility for or a stake in the change, such as the project manager and key stakeholders. It is not the case that change requests are reviewed only by third parties unrelated to the project, so this option is incorrect.

• ○イ

  正解 The change control board (CCB: Change Control Board) is a decision-making body that evaluates, from multiple perspectives such as cost, schedule, scope, quality, and risk, the impact that an incoming change request will have on the project, and decides whether to approve or reject that change. If the evaluation shows drawbacks such as increased cost or a postponed deadline, and these are judged not to be worth the benefit of the change, the change request can be rejected. Therefore, option イ, which states that 'a change request may be rejected on the grounds of increased cost or postponement of the deadline,' is the most appropriate.

• ×Incorrectウ

  Change requests also include those that involve a change in scope. The change control board is in fact a mechanism for evaluating and deciding on changes that affect the scope as well, and there is no restriction that it 'only accepts requests within the limits where the scope does not change.' Therefore this option is incorrect.

• ×Incorrectエ

  The order of review is reversed. A change request is first reviewed by the change control board, and that board (in which the project manager often also participates as a member) decides whether to approve or reject it. It is not a procedure in which the project manager approves all requests first and only then submits them to the board, so this option is incorrect.
