解説
問 46
Incorrectア
“System planning” is the most upstream process of the development life cycle, the stage where the policy and plan for what kind of system to build are decided. It happens before development starts, so it is not a term that refers to modifying or changing a program after development.
Incorrectイ
“System operation” refers to the work of keeping a completed system running from day to day (starting it up, monitoring, backups, and so on). It is the management of the operation itself, and is distinct from the work of modifying or changing the program itself.
- ウ
正解 The correct answer is ウ, “Software maintenance”. A system lives out its whole life along the flow of “planning → requirements definition → development → operation → maintenance”. After development is finished and the system enters production operation, the work of fixing or altering the program to repair bugs, respond to changes in laws or business, add features, and so on is called “software maintenance”. The statement in the question, that a program is modified or changed after system development, is exactly the definition of maintenance itself, so ウ is correct.
Incorrectエ
“Requirements definition” is a pre-development process, the stage where the functions and performance required of the system are clarified and turned into specifications. This too is work done before development rather than after, so it is not a term that expresses modification or change.
ここがポイント
- The system development life cycle proceeds in the order “planning → requirements definition → development → operation → maintenance”. Grasp where each process sits within the life cycle.
- Software maintenance is the process of modifying and changing a program after it goes into production operation, handling bug fixes, responding to environmental changes, feature improvements, and the like.
