Tool integration in evolving information systems environments

Abstract

Evolution is a fact of life in information systems. Not only systems evolve but also their development processes. IS environments must therefore be designed for accommodating and managing change. The management of process meta models in repositories is one important step; we show how process traceability models and process guidance models can be developed and related in a standard repository framework. In addition, the currently available tool integration along the presentation, data, and control perspectives have to be augmented for process integration. In our process-adaptable and interoperable tool concept, tool behavior is directly influenced by the process guidance model and automatically traced according to the traceability model. The approach is demonstrated with a prototype requirements engineering environment developed in ESPRIT project NATURE.
