IPA IP 2022 Question 7
A question IPA Japan published in 令和4年度 ITパスポート試験 公開問題 問7, translated into English. ITPEC is based on the same exams.
For the purpose of optimizing business operations and information systems, the current state is first grasped in four layers, for example, business, data, application, and technology, and the ideal image that serves as the goal is set. Next, the gap between the current state and the ideal is clarified, and the improvement activities toward the ideal image that serves as the goal are defined as a migration plan. Which of the following is the most appropriate technique for such optimization?
Explanation
EA (Enterprise Architecture) — it describes the current and ideal states of business and systems in layers, finds the gap and sets out a migration plan.
EA is a technique for optimizing the business operations and information systems of a whole organization. It models them in four layers: business (functions and processes), data (the information used), application (the systems that process it) and technology (the platforms they run on). For each layer it describes the current state (As-Is) and the ideal target (To-Be); comparing the two (gap analysis) shows what must change, and the improvement activities that close the gap become the migration plan.
Answer (b)
Why not others:
- •(a) — BI analyses a company's accumulated data (data warehouse, OLAP, dashboards) to support decisions; it does not design a target state
- •(c) — MOT manages technology so that innovation turns into business value; it is technology strategy, not layered modelling of business and systems
- •(d) — SOA builds systems by combining reusable services through standard interfaces; a design approach, not a plan from the current state to the ideal
Key rule: Four layers (business, data, application, technology), As-Is and To-Be, gap analysis and a migration plan: that is Enterprise Architecture.
