解説
問 21
Incorrectア
The operation process is the stage where the completed system is run in the production environment and daily operation, monitoring, and user support are carried out. It is located downstream in the life cycle and does not include the work of planning a system that is yet to be built.
Incorrectイ
The development process is the stage where design, programming, and testing are performed based on finalized requirements to actually build the system. The earlier planning work that decides what to build has already been finished before this stage.
- ウ
正解 The correct answer is ウ (Planning). In the Common Frame (SLCP), the software life cycle is understood as the flow “Planning → Requirements definition → Development → Operation → Maintenance.” Among these, the planning process is the most upstream stage, where what kind of system to build is decided based on business needs and issues, and it consists of two activities: formulating a systemization concept and formulating a systemization plan. In formulating the systemization plan, in order to realize the systemization concept, the scope of the target business operations, the development structure, the schedule, costs and benefits, risks and so on are organized, and an overall plan that includes the validity of the investment is put together. In other words, the formulation of a systemization plan asked about in this question is exactly an activity included in the planning process, so ウ is correct.
Incorrectエ
The requirements definition process is the stage that takes over the plan drawn up in the planning process and concretely defines the required functions, performance, and other requirements for users and business operations. Because it is the stage that comes after the planning process, it does not itself include the formulation of the systemization plan.
ここがポイント
- The processes of the Common Frame (SLCP) are arranged in the order “Planning → Requirements definition → Development → Operation → Maintenance”; remember that planning is the most upstream one.
- The planning process consists of two activities: formulating a systemization concept and formulating a systemization plan. It is the stage where the policy, scope, structure, and cost-effectiveness of systemization are settled starting from business issues.
