Business Process Improvement (BPI) is a high priority topic for modern enterprises. However, due to the distributed knowledge, conducting BPI projects has become challenging in times of inter-organizational business networks. For supporting the elicitation, analysis, and sharing of knowledge by practitioners, we describe how semi-formally described domain knowledge on BPI and knowledge on problem-solving techniques is transformed into an implementation-oriented representation in the form of a modeling tool. Thus, we revert to the FDMM formalism (Formalism for Describing ADOxx Meta Models and Models) that permits to bridge the gap between semi-formal meta models and those that are executable on the ADOxx meta modeling platform.
