IPA IP 2025 Question 27
A question IPA Japan published in 令和7年度 ITパスポート試験 公開問題 問27, translated into English. ITPEC is based on the same exams.
For the purpose of optimizing business operations and information systems, it is desired to clarify the gap between the current state and the ideal on the basis of grasping the current state of business operations and information systems and setting the ideal image that serves as the goal, and to define the improvement activities toward the goal as a migration plan. Which of the following is the most appropriate technique used in this case?
Explanation
EA (Enterprise Architecture) — it models the current and ideal states of business and systems, finds the gap, and sets out a migration plan.
EA is a technique for optimizing the business and information systems of a whole organization. It describes the current state (As-Is) and the target ideal (To-Be), usually in four layers: business, data, application and technology architecture. Comparing the two (gap analysis) shows what has to change, and the improvement activities that close the gap are laid out as a migration plan. The question describes this sequence step by step.
Answer (b)
Why not others:
- •(a) — BI analyses the data a company has accumulated (data warehouse, OLAP, dashboards) to support decisions; it does not design a target state
- •(c) — MOT links technological innovation to the business so that technology creates value; it is about technology strategy, not the gap between business and systems
- •(d) — SOA builds systems by combining reusable services through standard interfaces; it is a design approach for systems, not a method of planning from the current state to the ideal
Key rule: As-Is, To-Be, gap analysis, migration plan: that cycle, applied to business and systems across the organization, is Enterprise Architecture.
