解説
問 27
Incorrectア
BI (Business Intelligence) is a method or mechanism for analyzing and visualizing the large volumes of data accumulated in a company so as to support management and operational decision-making. Its purpose is data utilization; it is not a method for defining a migration plan from the gap between the current state and the ideal so as to optimize business operations and systems.
- イ
正解 The correct answer is イ, “EA (Enterprise Architecture)”. EA is a systematic method for optimizing the business operations and information systems of an entire organization: first you grasp the current state (As-Is), then you set a target ideal state (To-Be). By comparing the two, you clarify the gap between the current state and the ideal, and you define the improvement activities for closing that gap as a migration plan. The sequence in the question, “grasp the current state, set the ideal state, clarify the gap, define the migration plan”, is exactly how EA proceeds, so イ is the most appropriate method for optimizing business operations and systems.
Incorrectウ
MOT (Management of Technology) is a technology-management method that links technology to management in order to drive business growth. Its focus is on management strategy through the use of technological innovation; it is not a method for analyzing the gap between the current and ideal states of business operations and information systems and then creating a migration plan.
Incorrectエ
SOA (Service Oriented Architecture) is a design philosophy or architecture that componentizes business processing into independent units called “services” and flexibly builds systems by combining them. It is a way of building systems, not a method for defining a migration plan toward overall optimization based on the gap between the current state and the ideal.
ここがポイント
- EA (Enterprise Architecture) is a method for organizing the current state (As-Is) and ideal state (To-Be) of business operations and systems, clarifying the gap, drawing up a migration plan, and thereby optimizing the entire organization.
- Remember each by distinguishing its purpose and target: BI = decision support through data analysis, MOT = technology management, SOA = a way of building systems in units of services.
