解説
問 20
Incorrectア
The mistake is advancing the management strategy and the information strategy independently of each other. The information strategy is a means of realizing the management strategy, so the two must be coordinated and aligned; if they are formulated separately, the result is a system that does not contribute to the business. It is true that in practice different parties may formulate each one, but that is not a reason to proceed independently.
Incorrectイ
The mistake is aiming to automate the current business processes themselves with IT. That merely endorses the current state (As-Is) and locks in even inefficient operations as they are. In informatization, the business processes themselves should be reviewed against the management strategy (a BPR-style improvement); surveying current operations is the starting point, not the goal to reach.
- ウ
正解 An information strategy is a plan that defines how information systems will be used in order to realize the management strategy, so its basic premise is that it must be subordinate to, and aligned with, the management strategy. Choice ウ says to clarify the ideal form (To-Be) that the information system should take and to examine whether its purpose and functions conform to the management strategy — which is exactly this alignment check itself. To make IT useful for realizing the management strategy, as the question asks, you must draw the ideal form and constantly verify its fit with the management strategy, so that building the system does not become an end in itself. Therefore ウ is the most appropriate.
Incorrectエ
The mistake is evaluating only the initial cost at the formulation stage and deferring operation and maintenance costs to the time operation begins. System costs must be evaluated as the total cost of ownership (TCO) across introduction, operation, maintenance, and disposal; operation and maintenance account for a large share, so failing to estimate them at the formulation stage leads to a wrong investment decision.
ここがポイント
- The information strategy is a means of realizing the management strategy, and being aligned with the management strategy is the most important point to keep in mind when formulating it (management strategy → information strategy, a subordinate relationship).
- Informatization is not a simple automation of current operations (As-Is); it involves reviewing business processes by drawing the ideal form (To-Be). Also, costs should be evaluated not by initial cost alone but by TCO, which includes operation and maintenance.
