The method bases on object-orientation to handle complexity, reuse to gain efficiency as well as product quality, and prototyping to enable test-based verification and valida- tion early in the development process. To demonstrate the applicability and efficiency of this method, the results of an extensive case study are introduced.enText/Conference Paper1617-5468
