    Additional Information in Business Processes: A Pattern-Based Integration of Natural Language Artefacts
    (Modellierung 2014, 2014) Bittmann, Sebastian; Metzger, Dirk; Fellmann, Michael; Thomas, Oliver
    Business process modelling initiatives frequently make use of semi-formal modelling languages for depicting the business processes and their control flows. While these representations are beneficial for the analysis, simulation and automatic execution of processes, they are not necessarily the best option to communicate process knowledge required by employees to execute the process. Hence, textual process representations and their transformation to semi-formal models gain importance. In this paper, a pattern-based modelling approach positioned in between the two extremes of informal text and semi-formal process models is derived. The patterns offer a basis for a seamless integration of natural language and business process models. In particular the business process modelling patterns, which have to rely on human interactions are focussed. For those patterns an integrated representation of information that support the manual execution is developed. The approach fosters the contribution by employees of the operative business, since it does not rely on classical modelling paradigms, but uses natural language for modelling business processes.

    The Next Generation – Design and Implementation of a Smart Glasses-based Modelling System
    (Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 13, Nr. 18, 2018) Metzger, Dirk; Niemöller, Christina; Jannaber, Sven; Berkemeier, Lisa; Brenning, Lukas; Thomas, Oliver
    Technical services in innovative business models are becoming increasingly complex. Thus, comprehensive IT-support is crucial for service delivery. Content for those IT-support systems is captured by modelling relevant service processes. Aside the intangibility and integrativity, services are characterized by the complexity of their structure. So, the traditional modelling approaches executed by modelling experts are challenging. To overcome those challenges, we developed a concept to model service processes at the point-of-service while executing the service itself. The process executer (e. g. the technician) is empowered by smart glasses that do not limit his scope of actions. Additionally, the glasses guide through the (runtime) modelling and allow easy capturing of service processes during the execution. We followed a design science-oriented approach. First, we identified relevant process blocks from literature for runtime modelling (analysis). Afterwards, we built related software components for the process blocks (design). We do so by proposing an implementation and an architecture for a smart glasses-based modelling system. Finally, we evaluated the concept by prototyping and demonstrating the system by means of a real-world service process (evaluation). Our approach tackles challenges on how new technology can enhance the modelling at the point-of-service, which process blocks are relevant and how domain experts can be integrated into the modelling process itself. The practical implications are towards new chances of capturing processes.

    Process Modeling Recommender Systems - A Generic Data Model and Its Application to a Smart Glasses-based Modeling Environment
    (Business & Information Systems Engineering: Vol. 60, No. 1, 2018) Fellmann, Michael; Metzger, Dirk; Jannaber, Sven; Zarvic, Novica; Thomas, Oliver
    The manual construction of business process models is a time-consuming, error-prone task and presents an obstacle to business agility. To facilitate the construction of such models, several modeling support techniques have been suggested. However, while recommendation systems are widely used, e.g., in e-commerce, these techniques are rarely implemented in process modeling tools. The creation of such systems is a complex task since a large number of requirements and parameters have to be taken into account. In order to improve the situation, the authors have developed a data model that can serve as a backbone for the development of process modeling recommender systems (PMRS). This article outlines the systematic development of this model in a stepwise approach using established requirements and validates it against a data model that has been reverse-engineered from a real-world system. In a last step, the paper illustrates an exemplary instantiation of the data model in a Smart Glasses-based modeling environment and discusses business process agility issues. The authors expect their contribution to provide a useful starting point for designing the data perspective of process modeling recommendation features that support business agility in process-intensive environments.
