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.

The FEA Service Component Reference Model (SRM) is intended for use in discovering government-wide business and application service components in IT investments and assets. It is a component-based framework that provides (independent of business function) a leveraged foundation to support the reuse of applications, application capabilities, components, and business services.

The Service Reference Model (SRM) Domain has a three level hierarchy (Service Domain, Service Type, and Service Component), as shown below.

Each definition in each level of the SRM Hierarchy has two properties: name and description. Depending on where they are in the hierarchy, some definitions have parents and child properties as well. For FY05, SRM definitions did not have IDs.

There are seven service domains (see image below) that provide a top-level categorization of the service capabilities and categories from a business perspective.

These seven service domains comprise 29 service types that further categorize and define the capabilities of a service domain.

The service types define the second level of detail that describe a business-oriented service.

The next and final layer of the SRM is the component level. These 168 components (not shown) represent the lower level, logical “building blocks” of a business or application.
