This question's explanation and your answers so far.
ソフトウェア導入作業に関する記述 a～d のうち, 適切なものだけを全て挙げたものはどれか。 a 新規開発の場合, 導入計画書の作成はせず, 期日までに速やかに導入する。 b ソフトウェア導入作業を実施した後, 速やかに導入計画書と導入報告書を作成し, 合意を得る必要がある。 c ソフトウェアを自社開発した場合, 影響範囲が社内になるので導入計画書の作成後に導入し, 導入計画書の合意は導入後に行う。 d 本番稼働中のソフトウェアに機能追加する場合, 機能追加したソフトウェアの導入計画書を作成し, 合意を得てソフトウェア導入作業を実施する。
Includes a and c. Statement a says that in new development, deployment is done by the due date without creating a deployment plan document, but deployment without a plan document is inappropriate. Statement c also obtains agreement on the deployment plan document after deployment, but agreement should be obtained before deployment, so it is inappropriate. Neither is appropriate, so this is wrong.
Includes b, c, and d. Statement b says the deployment plan document is created after the deployment work is carried out, but the plan document should be made before deployment, so the order is reversed. Statement c also obtains agreement after deployment, which is inappropriate. Besides the appropriate d, it includes the inappropriate b and c, so this is wrong.
Includes b and d. Statement d is appropriate, but b creates the plan document and obtains agreement after the deployment work, a reversal of the order, which is inappropriate. Because it includes the inappropriate b, the option as a whole is wrong.
正解 In software deployment, the principle is to first create the deployment plan document, obtain the stakeholders’ agreement, and only then carry out the deployment work. Statement d says that when adding functionality to software in production operation, a deployment plan document is created, agreement is obtained, and then the deployment work is carried out, which satisfies the correct order of plan, then agreement, then implementation. Only d is appropriate, so the answer エ, which lists only d, is correct.
