解説
問 7
Incorrectア
BI (Business Intelligence) is a method and mechanism that analyzes and visualizes the large volume of business data accumulated in an enterprise and uses it for management and operational decision-making. It is not a method that organizes the gap between the current and ideal states across four layers to achieve whole optimization, so it is incorrect.
- イ
正解 The correct answer is “イ EA (Enterprise Architecture).” EA is a method that systematically captures an enterprise’s business operations and information systems by dividing them into four architecture domains — business, data, application, and technology — and organizes and improves them from a whole-optimization perspective. You first assess the current state (As-Is) of each domain, set the target ideal state (To-Be), clarify the gap between the two, and then compile the improvement activities for approaching the ideal state into a migration plan. The stem’s description corresponds exactly to EA’s philosophy and approach. The keywords of four layers plus As-Is / To-Be / migration plan point uniquely to EA.
Incorrectウ
MOT (Management of Technology) is an approach that manages technology and R&D by linking them to business as a source of business value and competitiveness. It is not a method that optimizes business operations and information systems across four architecture layers, so it is incorrect.
Incorrectエ
SOA (Service Oriented Architecture) is a design philosophy and architectural style that designs business functions as independent “service” components and flexibly builds systems by combining them. It is not itself the whole-optimization method of assessing the current state, setting the ideal state, analyzing the gap, and making a migration plan, so it is incorrect.
ここがポイント
- EA (Enterprise Architecture) = a method that captures business operations and information systems across four layers — business, data, application, and technology — and organizes and improves them from a whole-optimization perspective.
- EA’s basic procedure follows this flow: assess the current state (As-Is) → set the ideal state (To-Be) → clarify the gap between the two → formulate a migration plan toward the ideal state.
