    Do We Need a Standard for EPC Modelling? The State of Syntactic, Semantic and Pragmatic Quality
    (Enterprise Modelling and Information Systems Architectures (EMISA 2013), 2013) Fellmann, Michael; Bittmann, Sebastian; Karhof, Arne; Stolze, Carl; Thomas, Oliver
    The quality determination of business process models is a complex and demanding task. In literature, a plethora of different quality criteria can be identified and are respectively used by practitioners. The selection of quality criteria depends on the one hand on the respective preferences of the individual modeller. On the other hand, it is prescribed by the modelling language in use, as it has embodied specific criteria e.g. based on its syntax. For the widespread EPC, no comprehensive overview of existing aspects for the evaluation of an EPC model's syntactic, semantic and pragmatic quality exists. With this investigation, we present such an overview and put the identified aspects into a holistic perspective based on the identified and relevant literature.

    Invigorating event-driven process chains - towards an integrated meta model for EPC standardization
    (Modellierung 2016 - Workshopband, 2016) Jannaber, Sven; Karhof, Arne; Riehle, Dennis M.; Thomas, Oliver; Delfmann, Patrick; Becker, Jörg
    When deciding about appropriate modelling languages, the degree of standardization often represents an important decision criterion. Although the EPC is commonly used for process modelling in the last decades, the absence of an official standard leads more and more to its nonconsideration. A coherent meta model is a pillar for the specification of process modelling languages. Accordingly, this work builds the basis for further standardization by providing an integrated meta model for the EPC. The resulting meta model therefore supports the invigoration of the EPC by impelling the future standardization effort.

    On the de-facto standard of event-driven process chains: how EPC is defined in literature
    (Modellierung 2016, 2016) Riehle, Dennis M.; Jannaber, Sven; Karhof, Arne; Thomas, Oliver; Delfmann, Patrick; Becker, Jörg
    The Business Process Modelling Notation (BPMN) and the Event-driven Process Chain (EPC) are both frequently used modelling languages to create business process models. While there is a well-defined standard for BPMN, such a standard is missing for EPC. As a standard would be beneficial to improve interoperability among different vendors, this paper aims at providing the means for future EPC standardization. Therefore, we have conducted a structured literature review of the most common EPC variants in IS research. We provide a structured overview of the evolution of different EPC variants, describe means and capabilities and elaborate different criteria for decision-making in regard to including EPC variants in a standardization process.

    On the de-facto standard of event-driven process chains: reviewing EPC implementations in process modelling tools
    (Modellierung 2016, 2016) Karhof, Arne; Jannaber, Sven; Riehle, Dennis M.; Thomas, Oliver; Delfmann, Patrick; Becker, Jörg
    Nowadays, most process modelling tools implement popular modelling languages such as the Business Process Model and Notation (BPMN) or the Event-driven Process Chain (EPC). However, in contrast to BPMN, no effort has yet been undertaken to standardize the EPC language, thus rendering EPCs as being merely a de-facto standard for business process modelling. Subsequently, this paper addresses this issue by laying ground for a successful EPC standardization. To achieve this task, several process modelling tools have been evaluated regarding their implementation of the EPC language with the objective to derive consensus about important language constructs. The evaluation reveals that there is a high degree of variety in the way tools implement EPCs. Especially syntax, semantic and pragmatic of the EPC language are not perceived homogenously and, in fact, commonly neglected. Hence, our research provides valuable implications for further EPC standardization by highlighting the state-of-the-art of the EPC from a software point of view.
