    A Maturity Model for Assessing the Digitalization of Public Health Agencies
    (Business & Information Systems Engineering: Vol. 65, No. 5, 2023) Doctor, Eileen; Eymann, Torsten; Fürstenau, Daniel; Gersch, Martin; Hall, Kristina; Kauffmann, Anna Lina; Schulte-Althoff, Matthias; Schlieter, Hannes; Stark, Jeannette; Wyrtki, Katrin
    Requests for a coordinated response during the COVID-19 pandemic revealed the limitations of locally-operating public health agencies (PHAs) and have resulted in a growing interest in their digitalization. However, digitalizing PHAs – i.e., transforming them technically and organizationally – toward the needs of both employees and citizens is challenging, especially in federally-managed local government settings. This paper reports on a project that develops and evaluates a continuous (vs. a staged) maturity model, the PHAMM, for digitalizing PHAs as a cornerstone of a digitally resilient public health system in the future. The model supports a coordinated approach to formulating a vision and structuring the steps toward it, engaging employees along the transformation journey necessary for a federally-managed field. Further, it is now being used to allocate substantial national funds to foster digitalization. By developing the model in a coordinated approach and using it for distributing federal resources, this work expands the potential usage cases for maturity models. The authors conclude with lessons learned and discuss how the model can incentivize local digitalization in federal fields.

    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.

    Kennzahlenbasierte Analyse von Geschäftsprozessmodellen als Beitrag zur Identifikation von SOA Services
    (Modellierung betrieblicher Informationssysteme (MobIS 2008), 2008) Esswein, Werner; Weller, Jens; Stark, Jeannette; Juhrisch, Martin
    Seit 2005 läuft an der Universität Münster ein Projekt zum Aufbau einer Informationssystem-Architektur. Die Architektur folgt dabei dem Paradigma der Serviceorientierten Architektur (SOA). Im Verlauf des Projektes wurden Prozesse dokumentiert, auf deren Grundlage Services implementiert werden sollen. Eine manuelle Ermittlung der Prozesse die als Servicekandidaten geeignet sind hat sich jedoch als ineffizient herausgestellt. In diesem Beitrag wird deshalb ein Ansatz vorgestellt, bei dem die Identifikation von Servicekandidaten durch Kennzahlen unterstützt wird, die automatisiert aus Prozessmodellen generiert werden. Durch die Integration der Kennzahlengenerierung in ein Modellierungswerkzeug konnte der Aufwand der Serviceidentifikation wesentlich verringert werden.

    The selection of modeling grammars
    (Modellierung betrieblicher Informationssysteme (MobIS 2010). Modellgestütztes Management, 2010) Esswein, Werner; Stark, Jeannette; Schlieter, Hannes
    Information systems developers such as business process engineers use Conceptual Modeling to understand the information system's application domain and to derive such a system's requirements. For Conceptual Modeling an appropriate modeling grammar needs to be selected. Approaches have been identified to evaluate and select a modeling grammar. It is supposed that theorybased approaches contribute to a more effective selection of modeling grammars than non-theory-based approaches. However, only two approaches that are theorybased identified lead to a single modeling grammar: Cognitive Fit and Ontology. Using both approaches as complements results more effective to solve a specific (conceptual) modeling task than the individual approaches do. Therefore, we combine both approaches to a procedure that facilitates a theory-based approach to select a modeling grammar.
