Abstract—Business modeling for service engineering aims at flexible transformation of business logic into software code. The ISE framework is an interdisciplinary approach which embraces this concept to engineer services. This paper discusses work related to business modeling, introduces the ISE framework, and examines three areas for improvements. The first improvement addresses a firm terminology in that it reduces term ambiguity. The second improvement proposes additional concepts and meta models to advance the framework’s semantic. The last improvement presents an initial integrated procedure model with eleven steps, which will guide and support the modeler through the service engineering process.
