This framework is being used in a number of other countries and some state governments in Australia. The framework and these reference models have been endorsed by the Australian Government’s Chief Information Officers’ Committee. Developing an architecture framework is a large undertaking and one that is never really finalised. As a result, we decided to release the AGA in a series of versions, with each new version building on the last. This version adds value by incorporating the Performance Reference Model, further feedback from agencies and a substantial revision of the Business Reference Model. We look forward to further feedback as the reference models are used by agencies for projects and proposals. Agencies are not required to replace their existing frameworks with the AGA. However, for those that do not already have an architecture in place, or have one that is under review, we strongly recommend that you adopt the AGA. A sound architecture framework will support government by providing a useful context for decision- making and help agencies develop capabilities needed for the future. In particular, it will support agencies to operate across traditional boundaries to improve service delivery and deliver more responsive policy implementation. While this version extends the use of Australian examples, there are several US examples, some US terminology and other parts that are yet to be assessed. Their replacement with contemporary Australian examples will continue over time, but at present they have been retained. The framework contains five reference models. In this version, we present the Business Reference ii Model and have also refreshed the Service, Data and Technical Reference Models.
