FEAF 1 – integrated Reference Model Architect (iRMA)

The integrated Reference Model Architect (iRMA) extension for System Architect assists departments and agencies in incorporating and using the Office of Management and Budget (OMB) reference models as efficiently as possible.

iRMA supports use of the OMB reference models, and subsequent creation and publishing of Exhibit 300/Exhibit 53 reports, in the following ways:

▪It provides a single, consistent location for capturing the different reference model components that are supported, provided by, or used by an agency’s systems and or applications.

▪It provides utilities to automatically import the XML files that reflect the Office of Management & Budget (OMB) reference models.

▪It automatically generates Exhibit-300/53 output reports from repository information into Microsoft Word table format. These reports are for the BRM, PRM, SRM and TRM, and are generated in exact E300 format. The tables output can be pasted into the appropriate sections of the E300.

▪It provides consistency reports for Exhibit 300/53 and enterprise architecture repository data validation.

The following sections provide background information concerning the OMB reference models:

The metamodel used in the iRMA product to capture the FEA Reference models is pictured below.

The Business Reference Model (BRM) is a graphical, hierarchical representation of the federal government day-to-day business operations and activities. The BRM represents the first layer of the Federal Enterprise Architecture, which presents the business using a functionally driven approach.

For more information, see Business Reference Model (BRM)

Performance Reference Model (PRM) has a four level hierarchy (Measurement Area, Measurement Category, Generic Measurement Indicator, and Operational Measurement Indicator) as shown below.

For more information, see Understanding the Performance Reference Model (PRM)

The Service Component Reference Model (SRM) is a business-driven, functional framework that classifies Service Components with respect to how they support business and performance objectives. The SRM, constructed hierarchically, is structured across horizontal service areas that, independent of the business functions, can provide a foundation for reuse of applications, application capabilities, components, and business services.

For more information, see Understanding the Service Component Reference Model (SRM)

The FEA Technical Reference Model (TRM) provides a foundation to describe the standards, specifications, and technologies supporting the secure delivery, exchange, and construction of business (or Service) components and e-Gov solutions. The FEFA TRM unifies existing Agency TRMs and electronic Government (e-Gov) guidance by providing a foundation to advance the reuse of technology and component services from a Government-wide perspective.

The OMB’s Exhibit 300 and Exhibit 53 have been in use for several years as part of the Federal Government’s capital planning and investment control process. Reflecting the multiple purposes and uses of the budget information, they are complex data input forms, which are continually evolving.
