    Cognitive Efficient Modelling Using Tablets
    (Enterprise Modelling and Information Systems Architectures (EMISA 2013), 2013) Stark, Jeannette; Burwitz, Martin; Braun, Richard; Esswein, Werner
    Recently, conceptual modellers have to choose between modeling tools running on tablets or in a common PC environment. This choice has some implications on how cognitive efficient the modeling process is. While using touch input (given on a tablet) eyes and hand are directly coordinated, which supports human gaze behaviour. On the contrary, modelling with a mouse (given in a common PC environment) does not allow direct eye-hand coordination and therefore needs additional effort to coordinate eye and hand. This effect is investigated within a two-group laboratory experiment using BPMN as a modeling language and thus assesses if modeling on tablet is cognitive efficient. Furthermore, we derive assumptions how improve cognitive efficiency of modeling tools.

    Integrated enterprise modeling lectures for master classes
    (Modellierung 2016 - Workshopband, 2016) Braun, Richard; Wendler, Hannes; Benedict, Martin; Burwitz, Martin; Gand, Kai; Richter, Peggy; Rößler, Richard; Schlieter, Hannes; Stark, Jeannette; Esswein, Werner
    This paper presents the structure and contents of an integrated curriculum on teaching enterprise modeling for master students at a large German university. The module is composed of two main master classes (Business Engineering and Enterprise Modeling) and supplemented by an additional seminar and the final master thesis. The major classes respectively consist of twelve lectures and a large practical exercise part, in which the students have to solve given modeling tasks from two realistic case studies. The curriculum is organized and arranged according to an enterprise architecture framework in order to provide an integrated view on enterprise modeling and respective learning contents. It covers business-related and IT-related perspectives and their consequences for applicable modeling languages.

    Towards a multi-faceted framework for semantics in enterprise modeling languages
    (Modellierung 2016 - Workshopband, 2016) Braun, Richard
    The semantic specification of Enterprise Modeling Languages (EMLs) is a challenging task that is primarily caused by the immanent subjectivity in the context of enterprise modeling. This covers the interpretation of respective meta model constructs due to their references to the reality. In contrast, EMLs may also contain formal semantics in regard of automating specific parts. Despite the generally accepted relevance of semantics for the application of EMLs, current research lacks in the provision of appropriate description means and largely omits semantic investigations. This paper therefore proposes a multi-faceted framework for the analysis and description of EML semantics in order to increase the awareness of relevant influences. The framework consists of an ontic and epistemological dimension in its core, as material semantics finally address such fundamental aspects. On this basis, several wrapping dimensions are outlined: Conceptualization dimension, pragmatic dimension, representation dimension and the final consensus dimension.
