Exploiting an enterprise model during systems' requirements capture and analysis

The paper presents a framework for the inclusion of enterprise information in the development of a software requirements specification (SRS). An enterprise model is described which includes organisational, as well as business process components. The mission of an enterprise will determine a number of business objectives, which are translated into quantifiable goals under constraints imposed by the business environment. These goals specify targets for the associated business processes, and are critical in constraining and scoping the requirements for information systems. By ensuring the consistency of these requirements statements against the enterprise objectives, the process of iterative construction of an SRS is enhanced. Further, the impact of changes in customer requirements, both during and after the requirements engineering phase of software development may be assessed with greater reliability. The feasibility of the approach is illustrated with examples.
