What are the three powerful components of an EA Repository?

The Architecture Requirements Specification, controls, and gaps are fundamental components of an Enterprise Architecture (EA) Repository because they focus on the core elements necessary for managing and aligning architecture with business objectives. The Architecture Requirements Specification serves as a documentation tool that details the precise specifications needed to fulfill both business and technical requirements. This ensures that all stakeholders are aligned on what the architecture must achieve.

Controls are mechanisms put in place to ensure adherence to the defined architecture. They help guide decision-making and ensure compliance with the overall architectural vision. This is crucial in managing risks and ensuring that the architecture evolves as intended without straying from its strategic objectives.

Gaps refer to the discrepancies between the current state of the architecture and the desired future state. Identifying these gaps is essential as it helps organizations understand what needs to be addressed to meet strategic goals. This identification process promotes targeted planning and resource allocation, aiding in the overall effectiveness of the EA effort.

In contrast, the other options include elements that, while relevant to enterprise architecture, do not encapsulate the core operational components that form the backbone of an EA Repository. Strategic plans, milestones, and performance metrics focus more on the planning and measurement aspect rather than on the structural documentation and compliance required for effective architecture management.
