An approach to the design of knowledge-based systems D. Landes Institut fur Angewandte Informatik und Formale Beschreibungsverfahren Universitdt Karlsruhe, D-76128 Karlsruhe, Germany ABSTRACT The issue how to achieve a principled transition from knowledge acquisition to implementation such that a knowledge-based system (kbs) of high quality results is rarely discussed in the knowledge engineering literature. Here, this topic is ad- dressed in the context of the design phase of the MIKE approach to kbs develop- ment. In MIKE, design decisions are motivated primarily by non-functional requirements. Due to the iterative nature of the design process, design decisions have to be evaluated early. In MIKE, this can be achieved by experimental pro- totyping, but also by quantitative measures associated to requirements. Further- more, in order to improve transparency and traceability, the description of the design includes a record of the design decisions and their motivation in addit
