8 Technical Reference Model

8.1 Introduction

The Technical Reference Model (TRM) (Figure 8-1) is a component-driven, technical framework categorising the standards and technologies to support and enable the delivery of Service Components and capabilities. It also unifies existing agency TRMs and whole-of-government guidance by providing a foundation to advance the re-use and standardisation of technology and Service Components from a government-wide perspective.

Aligning agency capital investments to the TRM leverages a common, standardised vocabulary, allowing interagency discovery, collaboration and interoperability. Agencies and the Australian Government will benefit from economies of scale by identifying and re-using the best solutions and technologies to support their business functions, mission and target architecture.

Figure 8-1 illustrates the three-tiered TRM in a snapshot of the AGA metamodel Technical layer.  This snapshot shows the hierarchy of service areas, service categories and service standards in the AGA context and their connection to the Agency context through technology standards.  Further discussion is provided in the surrounding text.
