Within Australian Commonwealth government agencies, the Australian Bureau of Statistics (ABS) is perceived as a leader in its application of Enterprise Architecture (EA). This is a case study of some of the factors enabling ABS to successfully utilise EA. This paper examines how the ABS develops and applies EA (artefacts and processes) in its business environment. Outcomes of this study include some possible answers to organisations functioning without a formal EA. ISO 15704 (2005) was the basis for assessing completeness of the ABS EA. Further research needs to be undertaken to understand the value ABS is deriving from using an EA.
