This paper identifies the process for developing information system for Situation Awareness application domain and identifies novel process artifacts that need to be introduced along with existing approaches. Appropriately engineered method is an important requirement for successful implementation of any software system targeted at situation awareness. When it comes to Information System Development (ISD) for dynamic organizations, the method engineering plays even more critical role. The existing approaches for architectural description, method composition and process guidance are derived based on experiences from successful past implementations. Yet, how existing team utilizes the experience is the determining factor for its efficient use. Today?s organization, where one information system is the result of continuous efforts of multiple teams forming a virtual organization, calls for extending the approaches to get proper benefit from Method Engineering.
