Level of scope
Welcome » All things and their becoming » Techno Order (scope) » Level of scope


The Common Approach to Federal Enterprise Architecture (Federal Enterprise Architecture Framework ) which provides principles and standards for how architecture domains (business, information and technology architectures of Federal Enterprise Architecture Framework) should be developed across levels of scope that matter to the (US) Federal Government: international, national, federal, sector, agency, segment, system and application.

The figure below shows how the level of scope influences the level of detail and scope for analysis and documentation according to the requirements and planned usage for each architecture (Common Approach to Federal Enterprise Architecture (page 10).

For the planning detail and mission impact at the system and application levels, we propose to use the model elements at the Application Layer and Technology Layer of the ArchiMate Framework.

For the planning detail at the sector, agency and segment levels, we propose to use the model elements at the Business Layer of the ArchiMate Framework, and for the mission and business outcomes we propose to use the model elements of the Motivation Extension and the Implementation and Migration Extension.

The latter model elements are also relevant for the Mission impact at the federal, national and international levels.
