解説
問 36
Incorrectア
The claim that, regardless of scale, a system audit must always be conducted after deployment and an audit report must be prepared is wrong. A system audit is carried out by an independent third party as needed, and it is not something that must be performed for every software deployment. Requiring an audit uniformly even for small-scale deployments is excessive, and such an absolute assertion is inappropriate.
- イ
正解 イ is correct. Deploying software into the production environment (migration) carries the risk of halting business operations if it fails, so before the work begins it is essential to clearly establish the implementation structure — namely, who carries out the work (the implementers) and who bears responsibility (those responsible). If deployment proceeds while roles and responsibilities remain vague, decisions and responses will be delayed when a failure occurs, and it becomes impossible even to issue the instruction to roll back (restore the original state). Clarifying the implementation structure, together with the deployment plan and the deployment procedure manual, is fundamental to migration work, and this option is the most appropriate.
Incorrectウ
The claim that no deployment procedure manual is needed because deployment takes less time than development is wrong. Even when the work period is short, a deployment procedure manual is needed to prevent omissions and ordering mistakes and to ensure that the same steps are followed reliably even if the person in charge changes. A short duration is not a valid reason to omit the procedure manual.
Incorrectエ
The claim that, because the work is done only by the systems department, there is no need to document the work results and communicate them to the user department is wrong. It is the user department that actually uses the deployed software, and unless the deployment results, the changes, and the user manual are documented and communicated, the user department cannot operate it correctly. Sharing information with the relevant departments is an important part of deployment work.
ここがポイント
- When deploying software into the production environment (migration), clarifying the implementation structure — such as the implementers and those responsible — in advance is fundamental. If roles and responsibilities are vague, response and rollback at the time of a failure become impossible.
- Migration work involves preparing a deployment plan and a deployment procedure manual, and documenting the work results and communicating them to the user department. Extreme assertions such as always audit, no procedure manual needed, or no coordination needed should be judged inappropriate.
