- 1-Implementing C 4 ISR Architecture Framework-- An Australian Case Study

Architectures are an emerging approach for capturing complex knowledge about organisations and systems. Architectural approaches range from broad, enterprise focused approaches, through to approaches aimed at specific user communities. Within defence community, the US DoD's C4ISR Architecture Framework (C4ISR AF) is emerging as one method for capturing the knowledge of how a defence force can be organised for particular situations. This paper describes the process undertaken for the development of a case study of the C4ISR AF, the Joint Operational Architecture Demonstrator. The paper includes recommendations on the product construction sequence and the implications for the dependencies between the various C4ISR AF products. It also describes the development of tool support, in the form of customised extensions to PTech Inc.'s Framework, used by the team to develop the C4ISR AF products.
