Australian Government Architecture Reference Models Version 3.0

At an agency level, these business capabilities are represented by business services that are enacted through
the business processes created by the agencies. Business processes are, in turn, delivered and supported by
service components that are described in the Service Reference Model.
Refer to Figure 2-4 for the BRM tiered hierarchy 1 and its relationship to business services and business
processes.
2.3 Service Reference Model
Figure 2-4: BRM Structure
The Service Reference Model (SRM) is a business-driven, functional framework classifying services according
to how they support business and performance objectives. It serves to identify and classify horizontal and
vertical service components supporting agencies and their ICT investments and assets. The model aids in
recommending service capabilities to support the re-use of business components and services across the
Australian Government.
The SRM is organised across horizontal service areas, independent of the business functions, providing a
foundation for sharing and re-use of business services, applications, application capabilities and components.
Refer to Figure 2-55 for the SRM hierarchical structure.
