解説
問 34
Incorrectア
Stakeholders such as users and operations administrators need to be notified and coordinated with in advance, both before and during the release, so it is wrong to say that providing information only after completion is sufficient. Insufficient notification invites failures or confusion.
- イ
正解 The correct answer is “イ”. Release management is the activity of reliably deploying into the production environment what has been planned and authorized through change management, and its key point is to account for risks already at the planning stage. An appropriate release plan anticipates the case in which the work cannot be finished within the planned time (troubles or rework), and decides in advance on a back-out (rollback) procedure, spare time, and how to respond if the work is interrupted. Therefore “When planning a release, also anticipate the case in which the work cannot be completed within the planned time” is correct.
Incorrectウ
There is always a possibility of new failures occurring after a release, so post-release preparations such as readiness to roll back and coordination with monitoring and problem management are indispensable. “No preparation is necessary” is wrong.
Incorrectエ
It is appropriate to choose a phased rollout according to scale and risk (starting from a pilot or a subset of users and proceeding in stages), and a release is not necessarily carried out for all users at the same time regardless of scale, so this is wrong.
ここがポイント
- Release (and deployment) management is the activity of deploying changes authorized through change management into the production environment in a planned and reliable manner, and its key points are advance preparations such as a back-out procedure and spare time.
- A release should include advance notification to stakeholders, phased rollout according to risk, and preparation for post-release failures, and should anticipate unforeseen situations (such as time overruns) at planning time.
