解説
問 7
Incorrectア
The description “measures that anticipate possible troubles and minimize their social impact and other effects” refers to risk management / crisis management (a way of thinking close to a contingency plan or BCP), which differs in purpose from EA, a design method for overall optimization.
- イ
正解 Enterprise Architecture (EA) is a design method and framework for visualizing the current state (as-is) of an entire organization’s business operations and information systems, envisioning the desired future state (to-be), and optimizing the whole organization while closing the gap between them. Its core idea is to aim for overall optimization rather than the partial optimization of individual departments; it is generally organized into four architectures: business, data, application, and technology. Choice イ reads “a framework that visualizes the overall picture of current business operations and information systems, sets the desired future state, and performs overall optimization,” which is exactly this definition, so it is correct.
Incorrectウ
The description “an initiative that rethinks business processes from the ground up and radically redesigns them in order to achieve innovative improvements in cost, quality, service, and speed” refers to BPR (Business Process Reengineering), not EA.
Incorrectエ
The description “a mechanism that componentizes software into business-function units called services and combines them to build systems flexibly” refers to SOA (Service-Oriented Architecture), not EA.
ここがポイント
- EA (Enterprise Architecture) = a design framework that visualizes the current state (as-is), sets the desired state (to-be), and optimizes the entire organization. It aims for overall optimization, not partial optimization.
- Distinguishing confusable terms: BPR = radical redesign of business processes; SOA = building flexible systems through service componentization; risk / crisis management = minimizing the impact of troubles.
