解説
問 6
Incorrectア
Defining the details of the screens used in the business operations is a task of the system development process (the design stage), where requirements are turned into concrete specifications. At the planning stage, the detailed design of individual screens is not yet carried out.
Incorrectイ
Defining the scope and content of the system functions needed to realize the business operations is a task of the requirements definition process, which is carried out after system planning. It corresponds to the stage where, after the issues have been defined in the planning process, the functions needed to solve them are worked out in detail as requirements.
- ウ
正解 The system planning process is the process that takes over the preceding system conceptualization (identifying management-level needs and issues) and makes it concrete. In this stage, you first investigate the current state of the business operations targeted for systemization and analyze their problems, clearly define the issues to be solved by the system, and then draw up an overall plan covering the target scope, cost, schedule, and so on for the systemization. Option ウ, “Analyze the problems of the business operations targeted for systemization, and define the issues to be solved by the system”, is exactly the task carried out in this system planning process, so it is correct.
Incorrectエ
Identifying the management-level issues and needs that are aligned with the information system strategy is a task of the system conceptualization process, which comes before system planning. Taking over the issues and needs identified here, the following system planning process then proceeds to the concrete definition of issues.
ここがポイント
- The order of the processes in the Common Frame (system conceptualization → system planning → requirements definition → system development), and the distinction between the work carried out in each process.
- The core of the system planning process is to analyze the problems of the target business operations, define the issues to be solved by the system, and draw up the overall plan for the systemization.
