This document’s common approach to Federal EA provides principles and standards for how business, information, and technology architectures should be developed across the Federal Government so they can be used consistently at various levels of scope within and between agencies, as well as with external stakeholders. The common approach provides integration points with other governance areas including strategic planning, capital planning, program management, human capital management, and cyber security. The meta-model for The Common Approach to Federal EA is depicted in Figure 1 below:
Standardization in the Common Approach to Federal EA is based on the following items: primary outcomes, levels of scope, basic elements, sub-architecture domains, reference models, current and future views, transition plans, and a roadmap. When implemented, this standardization promotes comparable architectures across the Federal Government that will be more useful in managing change and enabling mission success with a lower total cost of ownership, faster time to market, and reduced duplication.
