The US Federal Governement has defined a [[Federal Enterprise Architecture]] structures of the five FEA reference models<ref name="WH05"/>:
* [[Performance Reference Model]] (PRM)
* [[Business Reference Model]] (BRM)
* [[Service Component Reference Model]] (SRM)
* [[Technical Reference Model]] (TRM)
* [[Data Reference Model]] (DRM)
The Federal Governement Business Reference Model (FA BRM) provides an organized, hierarchical construct for describing the day-to-day business operations of the Federal government. While many models exist for describing organizations - org charts, ___location maps, etc. - this model presents the business using a functionally driven approach. The Lines of Business and Sub-functions that comprise the BRM represent a departure from previous models of the Federal government that use antiquated, stovepiped, agency-oriented frameworks. The BRM is the first layer of the Federal Enterprise Architecture and it is the main viewpoint for the analysis of data, service components and technology<ref name="WH05"/>.
