Center node: "Towards Guiding Process Modelers Depending upon Their Expertise Levels"
  Abstract: Business process modeling is an important task for supporting business process management. One challenge of process modeling is the diversity of expertise from novice modelers to expert designers, which defines the need to provide different sorts of guidance during modeling. In this paper, we discuss these expertise differences based on the cognitive load theory and present an experiment that tested how people with different levels of expertise work with different instructional material presented as automatic feedback of a tool. Our conclusions suggest that guidance on reworking models needs to take different levels of expertise into account.
