Abstract: Petri nets are seen as suitable process modeling language since they lead to graphical process descriptions that can be understood by different people, since formal process analysis can be performed, and enaction of processes can be done on the basis of a process model described by Petri nets. We have developed a Petri net based process modeling language and applied it to various practical projects. From the experiences we have derived new concepts and techniques in order to enhance our approach. In this part we mainly discuss two aspects (1) modeling semi-structured process parts and (2) gathering the relevant information to be put into process models.
