Federal Enterprise Architecture Framework
New FEA web site


The Federal Enterprise Architecture (FEA) is a set of interrelated service-based reference models designed to facilitate cross-agency analysis and the identification of investments, gaps and opportunities for collaboration within and across US government agencies.

As the FEA reference models are very much focused on the provision of services, it is a useful resource for organisations developing a Service Oriented Architecture and categorising and defining their own Business Services (using the BRM), Application Services (using the SRM) and Infrastructure Services (using the TRM). The example content is clearly based on the provision of government services to its citizens, but the example can easily be adapted for other organisations in other industry sectors.

All of these reference models and their content are fully described in a Consilodated Reference Model document

Business Reference Model (BRM)

This is a function-driven framework for describing business operations of the US Federal government independent of the agencies that perform them.
It is useful reference for identifying the Products and Business Services that are offered by an organisation to its customers and stakeholders.


Service Component Reference Model (SRM)

This is Business and performance-driven functional framework that classifies service components with respect to how they support business and/or performance objectives.
Service Components are similar to ArchiMate's Application Services or Organisational Services.


Performance Reference Model (PRM)

Standardized framework to measure the performance of major IT investments and their contribution to program performance.
The PRM is structured around Measurement Areas, Measurement Categories, Measurement Groupings, and Measurement Indicators.

  • Measurement Areas – The high-level organizing framework of the PRM capturing aspects of performance at the output levels. This layer is directly linked to the performance objectives established at the agency and program levels. The PRM includes six measurement areas: Mission and Business Results, Customer Results, Processes and Activities, Human Capital, Technology, and Other Fixed Assets.
  • Measurement Categories – Collections within each measurement area describing the attribute or characteristic to be measured. For example, the Mission and Business Results Measurement Area include three Measurement Categories: Services for Citizens, Support Delivery of Services, and Management of Government Resources, corresponding to the Lines of Business in the BRM.
  • Measurement Groupings – Further refinement of categories into specific types of measurement indicators. For the Mission and Business Results Measurement Area, these groupings align to the Sub-functions of the BRM.
  • Measurement Indicators – The specific measures, e.g., number and/or percentage of customers satisfied, tailored for a specific BRM Line of Business or Sub-function, agency, program, or IT initiative.

Data Reference Model (DRM)

Model describing, at an aggregate level, the data and information that support program and business line operations.
Data Reference Model

Technical Reference Model (TRM)

This is a Component-driven, technical framework used to identify the standards, specifications, and technologies that support and enable the delivery of service components and capabilities.
