    Advanced Reduction Rules for the Verification of EPC Business Process Models
    (SIGSAND-EUROPE 2008: Proceedings of the Third AIS SIGSAND European Symposium on Analysis, Design, Use and Societal Impact of Information Systems, 2008) Mendling, Jan; Aalst, Wil van der
    Conceptual business process models such as Event-driven Process Chains (EPCs) play an important role in the business process management life cycle. The pro- blem in this context is that most of today’s commercial business process management tools provide only limited support for quality assurance beyond simple syntax checks. In this paper we focus on verification of behavioral correctness as one of the major qua- lity issues for process models. To be more concise, we introduce advanced reduction rules for EPCs in order to address the requirements of performance and identificati- on of errors in practice. We present the verification tool xoEPC that implements the reduction rules. It provides detailed feedback to the modeler where errors are located in the model, and generates a report on quality issues in a process model collection. We present the application of xoEPC to the analysis of the SAP reference model to illustrate the tool.

    The Impact of Activity Labeling Styles on Process Model Quality
    (SIGSAND-EUROPE 2008: Proceedings of the Third AIS SIGSAND European Symposium on Analysis, Design, Use and Societal Impact of Information Systems, 2008) Mendling, Jan; Reijers, Hajo
    Quality issues and their connection with structural aspects of process models have been recently studied, but there is still a notable lack of research into quality aspects of activity labels in business process models. In this paper, we investigate whether the guideline to use verb-object labels actually contributes to improved model quality in terms of less ambiguity and higher usefulness. In an explorative analysis of the activity labels in the SAP Reference Model we identify three labeling styles that differ in the degree of ambiguity they bring about. Based on these styles we design a survey to test the hypothetical connection between labeling style and quality. The results suggest that indeed the verb-object style is superior to other ways of constructing labels. Our findings are deemed to be useful for modeling practice.
