As consultant-educators, the authors created the extreme architecture framework (XAF) in order to quickly grasp an understanding of an organisation’s architecture from different perspectives. The framework is presented as a matrix of system types and architectural perspectives that is described by a single uncluttered diagram. Elements within the framework are defined along with the content that can include architectural representations, planning, and governance information. A discussion follows to show the relationship of the framework to planning, development, and governance activities. The minimalist framework presents a consolidated view of both human activity and software systems and can also help to foster a shared understanding between IT groups and business areas. It has been designed to answer a manager’s questions: • Which elements of the enterprise do I need to be aware of and understand; and • Which elements am I responsible for and need to manage?
