解説
問 46
- ア
正解 The correct answer is ア “DevOps”. DevOps is a coined term combining Development and Operations. It refers to an approach in which development staff and operations staff cooperate across organizational boundaries and use automation tools to support tasks such as version control and migration to the production environment (deployment), so that they can respond quickly and flexibly to requests such as specification changes. The three points in the question — “development and operations staff cooperate with each other”, “actively adopt automation tools”, and “respond quickly and flexibly” — are exactly the characteristics of DevOps, so ア is the most appropriate.
Incorrectイ
WBS (Work Breakdown Structure) is a method that hierarchically breaks a project's work down into smaller, more manageable units; it is a tool for project management. It has nothing to do with cooperation between development and operations or the adoption of automation tools, so it is incorrect.
Incorrectウ
Prototyping is a software development model in which a trial product (prototype) is made early in development for users to review, so that requirements can be finalized at an early stage. It is a technique for the requirements definition phase and is not a term for cooperation between development and operations staff or for automating production deployment, so it is incorrect.
Incorrectエ
Pair programming is an agile development practice in which two developers share one terminal, with one writing code and the other reviewing it, programming together. It is collaboration between developers, not cooperation between development and operations, and adopting automation tools is not its essence, so it is incorrect.
ここがポイント
- DevOps = Development + Operations. It refers to an approach in which both sides cooperate and, through automation of version control and deployment, respond quickly and flexibly to change requests.
- Distinguishing similar terms: WBS is work breakdown, prototyping finalizes requirements through trial products, and pair programming is a two-person development technique — none of them matches the core of DevOps, which is “cooperation between development and operations”.
