Which layer is not part of an Enterprise Architecture?

Business Architecture
System Analysis
Information Architecture
Delivery Systems Architecture

The correct answer is: System Analysis

The correct choice highlights the distinction between formal layers of Enterprise Architecture (EA) and related but separate practices. EA typically consists of several defined layers, including Business Architecture, Information Architecture, and Delivery Systems Architecture. Each of these layers has a specific focus within the framework of an enterprise. Business Architecture addresses the business strategy, governance, organization, and key business processes. Information Architecture deals with the structure of information and how it’s managed and governed within the organization. Delivery Systems Architecture pertains to the technology and infrastructure needed to deliver services and applications effectively. In contrast, System Analysis, while an important discipline within IT and project development, is not a formal layer of Enterprise Architecture. It often involves assessing and evaluating systems to ensure they meet organizational needs but does not constitute a part of the architectural layers outlined in EA frameworks. Thus, recognizing that System Analysis is a different discipline helps clarify the integrity and composition of Enterprise Architecture.
