Process Model Driven Requirements Engineering

This paper demonstrates an approach to requirements engineering with process models as the hub for a family of consistent sub-models. The process model taken as a starting point gives focus, and the different requirement perspectives are served through the enrichment of the process model in several dimensions. Different views into the model family give the well-known specification models; information models, exchange models, service models, etc. The family of related sub models are refined iteratively to describe the need for information (NFI), the need for services (NFS), a shared common information model (CIM) and refined domain information models (DIM). We call this family of interrelated sub models of information systems knowledge models, since they capture both the structure and the behaviour of the subject matter domain. Working in an integrated way with several models serves to enhance consistency and to test the quality of each particular model.
