Consolidated Reference Model

Federal Enterprise Architecture Framework Version 2

Overview of the Consolidated Reference Model

The Consolidated Reference Model of the Federal Enterprise Architecture Framework equips OMB and Federal agencies with a common language and framework to describe and analyze investments. It consists of a set of interrelated “reference models” designed to facilitate cross-agency analysis and the identification of duplicative investments, gaps and opportunities for collaboration within and across agencies. Collectively, the reference models comprise a framework for describing important elements of federal agency operations in a common and consistent way. Through the use of the FEAF and its vocabulary, IT portfolios can be better managed and leveraged across the federal government, enhancing collaboration and ultimately transforming the Federal government.

The five reference models in version 1 the Federal Enterprise Architecture have been regrouped and expanded into six in the current version of the Federal EA.


The Performance Reference Model (PRM) links agency strategy, internal business components, and investments, providing a means to measure the impact of those investments on strategic outcomes.


The Business Reference Model (BRM) describes an organization through a taxonomy of common mission and support service areas instead of through a stove-piped organizational view, thereby promoting intra- and inter-agency collaboration.


The Data Reference Model (DRM) facilitates discovery of existing data holdings residing in “silos” and enables understanding the meaning of the data, how to access it, and how to leverage it to support performance results.


The Application Reference Model (ARM) categorizes the system- and application-related standards and technologies that support the delivery of service capabilities, allowing agencies to share and reuse common solutions and benefit from economies of scale.


The Infrastructure Reference Model (IRM) categorizes the network/cloud related standards and technologies to support and enable the delivery of voice, data, video, and mobile service components and capabilities.


The Security Reference Model (SRM) provides a common language and methodology for discussing security and privacy in the context of federal agencies’ business and performance goals.

These reference models provide standardized categorization for strategic, business, and technology models and information. Using a common language to describe investments supports analysis and reporting across agency Enterprise Architectures and facilitates identification of opportunities for sharing and reuse of services and applications across agencies. Each reference model has its own taxonomy, methods, touch points, and use cases that provide examples of how the reference model can be applied.

The relationships between the reference models are important to understanding the overall CRM and its ability to provide value to the Federal Government. This is illustrated through the entity diagram of the meta-model below. The PRM is initiates the line of sight from the agency strategic plan, through the BRM, to the rest of the Enterprise Architecture. The SRM is ubiquitous, informing decisions made throughout the other sub-architectures to ensure that security is baked into IT systems from the beginning.

The reference models are consolidated via a highlevel metamodel:


The work with the metamodel and other details of FEAF-II is ongoing, partly internally in the US federal administration, but also in the wider EA community.
