解説
問 16
Incorrectア
Conducting interviews with frontline employees is useful for grasping how current operations actually run and what is inconvenient in day-to-day use, and it is indispensable when defining requirements or analyzing the current state (as-is). What is gathered there, however, is the troubles of individual departments and individual staff members, that is, requests from the frontline point of view. Piling such requests up does not yield the direction the company as a whole should take; it may even encourage optimization within each separate department and move things further away from overall optimization. As a means of securing alignment with the management strategy, which is a higher-level, company-wide kind of agreement, it is not appropriate.
Incorrectイ
A request for proposal (RFP) is a document in which the ordering party compiles the functions, requirements, budget, schedule, and so on that it wants when procuring a system, and presents it to vendors to invite proposals. It is prepared only after the overall optimization plan or the systemization plan has already been settled and the stage of procuring an individual system has begun, so it belongs to a later process than the formulation of the plan that this question asks about. It is not a means of matching the content of the plan to the management strategy, and neither in sequence nor in purpose can it be the answer.
- ウ
正解 The correct answer is ウ, Understanding the medium-term management plan. An overall optimization plan for an information system is a plan that avoids a proliferation of separately optimized systems built department by department; it describes, from the management point of view, the ideal future state (to-be) of the company-wide information systems and shows the path for reaching it. This is exactly the idea of EA (Enterprise Architecture): an information system is a means of supporting management, so the starting point of the plan always lies on the management strategy side. The document in which that management strategy takes concrete form is the medium-term management plan, which sets out the management goals, business directions, and priority measures for roughly the next three to five years. Only when the planner (the CIO or the information systems department) correctly understands it can they judge, in line with management intent, which business areas should be computerized first and what kind of information infrastructure will be needed, and thereby guarantee that the management strategy and the direction of computerization do not drift apart. Therefore ウ is the most appropriate thing needed to ensure alignment.
Incorrectエ
An audit report issued by an independent auditor is a document in which a certified public accountant or an audit firm expresses an opinion on the fairness of the financial statements, and what it covers is information from accounting periods that have already closed. It is a third party assuring the reliability of the financial condition of the company, not something that shows the future management strategy of which markets the company will compete in and how. Even if it is reviewed, one cannot learn the content of the strategy that the plan is supposed to be aligned with, so it cannot serve as a means of matching the overall optimization plan to the management strategy.
ここがポイント
- An overall optimization plan for an information system is a plan that starts from the management strategy and describes the ideal state of the company-wide information systems (the idea of EA, Enterprise Architecture). Because computerization is a means of management, the management strategy always stands above the plan when it is drawn up, and the key point is not to fall into department-by-department optimization by merely piling up frontline requests.
- The medium-term management plan is a document that puts the management strategy into concrete form as management goals, business policies, and priority measures for roughly the next three to five years, and it is the primary source to consult when checking alignment with the management strategy. An RFP (request for proposal) is a document of the procurement process that comes after the plan is fixed, and an audit report is a third party opinion on past financial information; neither of them shows the future strategy, and that distinction is worth remembering.
