問 17
Incorrectア
This is inappropriate because the project members on the development side unilaterally draw up the ideal vision without confirming it with the users. Moreover, it is submitted to the sales planning staff, who have no decision-making authority, so it does not constitute the agreement that finalizes the business requirements. The step of drawing out requirements from the users is missing.
- イ
正解 Business requirements definition is the work in which the business department that actually uses the system clarifies what it wants to achieve, and this is then formally agreed upon between the development side and the business side. Because this project is staffed only by members from the development department, it is necessary to directly gather the business needs from the users, namely the sales department head and the sales staff. In choice イ, the project members organize and summarize the needs they have gathered, and further reach agreement on them with the sales department head, who is responsible on the business side. This satisfies both essential steps of business requirements definition—collecting requirements from the users and forming agreement with the business side—so it is appropriate.
Incorrectウ
The current business flow merely copies the current way of doing things (As-Is) and is not in itself the requirements the system should realize. In addition, it only reports to the sales staff and has no procedure for obtaining agreement. This confuses grasping the current situation with business requirements definition.
Incorrectエ
Business requirements should be finalized through agreement by the business department that uses the system. If members on the development side merely have the requirements they identified through brainstorming approved by a project manager who is also on the development side, then the intentions of the users (the sales department) are neither reflected nor confirmed, resulting in self-serving requirements.
ここがポイント
- In business requirements definition, business needs are gathered from the actual users (the business department), then organized, and finalized by reaching agreement with the person responsible on the business side. They must not be decided by the development side alone.
- Grasping the current business flow (As-Is) is only an input to requirements definition and is not the business requirements themselves. Forming agreement with the users is indispensable for finalizing the requirements.
