Enterprise Engineering is defined as that body of knowledge, principles, and practices having to do with the analysis, design, implementation and operation of an enterprise. In a continually changing and unpredictable competitive environment, the Enterprise Engineer addresses a fundamental question: “how to design and improve all elements associated with the total enterprise through the use of engineering and analysis methods and tools to more effectively achieve its goals and objectives”...

An enterprise must be viewed from several perspectives if it is to be fully described and understood (Barnett 1994; ESPIRIT Consortium AMICE 1991). Previous work in the development of architectures by the Automation & Robotics Research Institute (Presley et al. 1993) describes a five view approach. The Business Rule (or Information) View defines the entities managed by the enterprise and the rules governing their relationships and interactions. The Activity View defines the functions performed by the enterprise (what is done) while the Business Process View defines a time sequenced set of processes (how it is done). The resources and capabilities managed by the enterprise are defined in a Resource View. Finally, the Organization View is used to define how the enterprise organizes itself and the set of constraints and rules governing how it manages itself and its processes.

The presence of an enterprise reference architecture aids an enterprise in its ability to understand its structure and processes. Similar to a computer architecture, the enterprise architecture is comprised of several views. The enterprise architecture should provide activity, organizational, business rule (information), resource, and process views of an organization.
