解説
問 4
- ア
正解 'Formulating a systemization concept' is the most upstream process in the planning process of the Common Frame. To realize the management strategy (the ideal form of business that the company aims for), it is the stage where you draw the overall picture and direction of which operations to systemize and how. At this stage, the premise is that the underlying management strategy has first been established, and the plan for utilizing the information system is formulated in line with it. Therefore, the correct prerequisite information is 'ア Management strategy'.
Incorrectイ
System requirements are a deliverable that is concretized in the 'requirements definition process' that follows the concept and plan; they are determined downstream as a result of formulating the systemization concept. They are not the prerequisite (input) for concept formulation, and the order is reversed, so this is incorrect.
Incorrectウ
The results of responses to the request for proposal (RFP) are information obtained at the procurement (vendor selection) stage, which selects the vendor entrusted with development, even later than the systemization plan. This is a process far downstream of concept formulation and cannot serve as prerequisite information, so it is incorrect.
Incorrectエ
The project promotion structure is the organization set up when launching the development project upon receiving the systemization concept and plan; it is not the input needed to formulate the concept. It is not a prerequisite for concept formulation but is decided in a later process, so it is incorrect.
ここがポイント
- Formulating the systemization concept is the most upstream process in the planning process, and its prerequisite (input) is the management strategy. Grasp the upstream-to-downstream flow: management strategy to systemization concept to systemization plan to requirements definition to procurement to development.
- 'Prerequisite information' refers to the upstream input. System requirements, the RFP response, and the promotion structure are all deliverables determined downstream of the concept, so they cannot be prerequisites.
