解説
問 25
Incorrectア
The project manager from the current system's development was involved in a past project and is not the party who fixes the business requirements of the new system to be built. Their past experience may be consulted for reference, but they are not a party whose agreement must be obtained.
Incorrectイ
The manager of the current system's maintenance vendor is an outsourced party that maintains the existing system and is not in a position to decide the business requirements demanded of the new system. They can be a source of maintenance information, but they are not an appropriate party for agreeing on business requirements.
Incorrectウ
The manager of the new system's development vendor is the side that receives the fixed requirements and implements the system (the builder), not the party that decides what is needed for the business. Agreement on requirements should be reached with the user department that owns the business content, whereas agreement with the development vendor belongs to the later stage of system requirements and development contracts.
- エ
正解 Business requirements definition is the process of clarifying and reaching agreement on what the new system should achieve for the business, and the party that owns this requirement is the user department that actually carries out that work. If development proceeds while the requirements diverge from the user department's intent, rework arises after completion because the result differs from what was wanted. To prevent this, the party from whom agreement on the requirement content must be obtained is the choice エ, the manager of the user department of the new system. Only once the user-department manager's agreement is secured are the defined business requirements finalized as the consensus of the business side.
ここがポイント
- Business requirements definition is the process of clarifying and agreeing on what the business side demands of the new system, and the party to agree with is the requirement's owner, i.e., the manager of the user department.
- The builder (development vendor) and the stakeholders of the past or current system are the side that realizes or references the requirements, not the party that finalizes and agrees on the business requirements themselves.
