Concerning object modeling, conceptual predesign proved useful in overcoming the impedance mismatch between conventional requirements analysis based on natural language and conceptual design. Within this contribution we will present first results on how the conceptual predesign model KCPM (Klagenfurt conceptual predesign model) may be used for the collection and mapping of dynamic requirements specifications (natural language text) to a state chart. This mapping is based on identifying specific requirements patterns within a predesign scheme that may be transformed into state diagram patterns.
