Federal Enterprise Architecture Framework (FEAF) does that for any U.S. federal agency and helps systems transcend interagency boundaries.  FEAF offers a shared approach for the consolidation of strategic, business, and technology management as a component of Organization Design and Performance Management.  The Enterprise Architecture methodology introduced under FEAF transcended several interagency boundaries.

The FEAF comprises of 6 interconnected Reference Models, linked through Consolidated Reference Model (CRM), each relating to a sub-architectural domain of the framework.

These Reference Models convey word-based abstractions of original architectural data and deliver a structure for relating significant elements of the FEA in a collective and uniform manner:

  1. Strategy Domain -> Performance Reference Model (PRM)
  2. Business Domain -> Business Reference Model (BRM)
  3. Data Domain -> Data Reference Model (DRM)
  4. Applications Domain -> Application Reference Model (ARM)
  5. Infrastructure Domain -> Infrastructure Reference Model (IRM)
  6. Security Domain -> Security Reference Model (SRM)

Discussed here is 1 of the 6 reference models of the Federal Enterprise Architecture Framework—the Business Reference Model (BRM), its structure, framework, touchpoints with other reference models, and BRM Taxonomy.


BRM is employed to explain the type of business functions at the system, segment, agency, sector, Federal, national, or international levels rather than giving an organizational vantage point.

Cross-government cooperation between the Executive departments and subsidiary agencies—as well as external partners—is promoted by describing the Federal government in this manner enabling:

  • Uncovering of possibilities for cost reduction.
  • Collaboration.
  • Shared services.
  • Solution reuse in agency IT portfolios and collaboration between and within agency.

BRM elucidates the “what we do” of the organization via the delineation of outcome-oriented and measurable functions and services.

BRM’s real usefulness and worth is gained when it is put to use effectively in business analysis, design, and decision support that aids in improving the working of an agency, bureau, or program.

BRM classification is organized as a 3-layer order, embodying Executive Branch Mission Sectors, Business Functions, and Services.

  • Mission Sector – Pinpoints 10 business functions of the Federal government in the Common Approach to Enterprise Architecture.
  • Business Function – Defines the Federal government functioning at high level, by means of budget function classification codes.
  • Service – Elaborates further what the Federal government does at a subsidiary or section level.

Mission Sector is exclusive to the executive branch of the Federal government.  This layer should be used appropriately for other organizations.

The 3 layers allow arrangement and analysis of IT investments and applications for an assortment of purposes.

All reference models are envisioned to work jointly.  BRM’s further mappings to other reference models contribute added context for the investment or activity.  Input for BRM is through Performance Reference Model (PRM) enabling BRM to feed other reference models.

BRM is intended to deliver agencies with a uniform means to classify their capital investments, detect areas for collaboration and reuse, centered on delivery of business capability.

BRM also aids in refining the general IT architecture to further improve mission outcomes. It extends decision-support abilities to stakeholders and various levels of staff, within and outside an agency, and across the Federal government.  From a Federal viewpoint, BRM permits discovery of prospects for joint effort and reuse of shared services, government-wide.  This collaboration takes 2 forms:

  1. Inter-agency
  2. Intra-agency

BRM is usable in combination with several architecture, development, or analysis methods to deliver all-inclusive standardized design, development, and governance abilities.  There are 3 primary types of BRM methods:

  • Business Architecture for Decision Support
  • Business Process Modeling
  • Business Process Modeling Notation (BPMN)
