解説
問 8
Incorrectア
Drawing up a system migration plan is the work of deciding the concrete steps for switching a target individual system over to a new environment (data migration, parallel running, cut-over procedures, and so on), and it is done in the development and deployment phase. It is not work performed at the stage of formulating the company-wide information system strategy.
Incorrectイ
Drawing up a system test plan is a plan for verifying quality during the development process of an individual system; it is work of the development phase. It is not addressed at the company-wide strategy-formulation stage.
- ウ
正解 The correct answer is “ウ Drawing up an IT investment plan.” The stage of formulating a company-wide information system strategy is the most upstream planning phase, where—based on the management strategy—the company decides in which areas and how much of its management resources (people, goods, money) to invest in IT. An IT investment plan sets the company-wide investment budget, priorities, and return-on-investment (ROI) policy; it is a company-wide decision, and it is drawn up precisely at this strategy-formulation stage. Planning and development of individual systems proceed later in line with this strategy, so ウ is the most appropriate.
Incorrectエ
Drawing up a procurement plan is the work of deciding how to arrange the hardware, software, external outsourcing, and so on needed to build an individual system, and it is done at the planning and development stage of the individual system. It is not work performed at the stage of formulating the company-wide information system strategy.
ここがポイント
- Distinguish the levels of information system strategy (company-wide level) and planning/development of individual systems (individual level). At the strategy-formulation stage, the company decides company-wide policies concerning the allocation of management resources, such as an IT investment plan.
- Migration plans, test plans, and procurement plans are all work of the development and deployment phase of individual systems, and their process stage differs from the strategy-formulation stage.
