    Development of a Domain-Specific Language for Run-Time Process Modelling
    (INFORMATIK 2017, 2017) Jannaber, Sven; Zobel, Benedikt; Riehle, Dennis M.; Thomas, Oliver; Becker, Jörg
    Wearable devices pose novel challenges to the BPM field. The advanced functionality in combination with the increased mobility has rendered devices such as smart glasses particularly suited for mobile process support. However, whereas this support is predominantly limited to information provision and workflow management, the glasses’ capability to be utilized for actual process modelling has yet to be investigated. As a first step, this paper proposes an outlook on the development of a process modelling language that is specifically tailored towards the application domain smart glasses and can be applied for both modelling and representing business processes using a glasses-based modelling environment. A demonstration case is provided to highlight the utilization of process modelling on smart glasses.

    Do not disturb! trust in decision support systems improves work outcomes under certain conditions
    (Mensch und Computer 2020 - Tagungsband, 2020) Müller, Lea S.; Meeßen, Sarah M.; Thielsch, Meinald T.; Nohe, Christoph; Riehle, Dennis M.; Hertel, Guido
    Organizations provide their employees with decision support systems (DSS) to facilitate successful decision making. However, the mere provision of a DSS may not be sufficient to facilitate beneficial work outcomes because employees often do not rely on a DSS. Therefore, we examined whether users’ trust in a DSS increases positive effects of DSS provision on several core work outcomes (i.e., performance, well-being, and release of cognitive capacities). Moreover, we examined whether trust effects on these work outcomes depend on specific context conditions (i.e., user accountability, distraction, and market dynamics). We tested our hypotheses in a laboratory experiment with N = 201 participants who received assistance by a DSS in a simulated sales planning scenario. In line with our assumptions, trust in the DSS was positively related to users’ performance and well-being. Moreover, the link between trust and strain as well as release of cognitive capacities were qualified by distraction, so that higher distraction diminished these links. No such moderation occurred for user accountability and market dynamics.

    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.
