Enterprise Architecture Body of Knowledge
Using an EA

The EA is a tool for many individuals within an enterprise to include executives, managers, engineering staff, cost analysts, domain experts, and end users. Managers and executives use the EA to ensure investments and systems are linked to the mission and strategy for an organization. They also use the EA for planning and sequencing of acquisitions to make sure investments are effective and non-redundant. Engineers analyze the EA for redundancy, consistency, integration, interoperability, performance, adherence to standards, and quality of design. They also use it as the basis for the supporting system / infrastructure implementation. The EA provides visibility and control over investments while providing a shared vision of the future direction across the enterprise.

This knowledge area provides references and guidance on how to use the EA. It may cover case studies on the use of EA to inform business, management, engineering, operations, or financial decisions. It may also include tools and techniques for cost/benefit analysis, systems engineering design, operations improvement, or EA data visualization.
