    Applying the Minimal Cost of Change Approach to inductive Reference Enterprise Architecture Development
    (Digital Enterprise Computing (DEC 2017), 2017) Timm, Felix; Sauer, Valentina
    Enterprise architectures (EA) help organizations to analyze interrelations among their strategy, business processes, responsibilities, application landscape and information structures. Such ambitious endeavors can be supported by using reference models for EAM. Although research thoroughly addresses the development of reference models, the characteristics of EA models are not investigated in this context. Our work therefore applies one approach for inductively constructing reference process models to the EA domain. We thus contribute to the reference modeling research field in general and its application to development of reference enterprise architectures in detail.

    The Data Perspective of Sensor-enabled Personal Work Support Systems
    (Mensch und Computer 2018 - Workshopband, 2018) Lambusch, Fabienne; Fellmann, Michael; Sauer, Valentina
    In today’s working world, work intensification and blurring boundaries between life domains pose major challenges. Stress resulting from high working pressure combined with a lack of opportunities for recre-ation can cause serious physical and mental health problems. As sensor technology has become ubiqui-tous and enables new kinds of data collection, it can serve as a foundation for sensor-enabled personal work support systems (SPWSS) assisting users in coping with high work demands while considering individual resources. Such systems could interpret collected data and generate recommendations geared towards maintaining the user’s health, productiveness and wellbeing. However, building systems of this type is a complex task due to the large number of sensors, devices, and software components that have to be integrated. Moreover, this kind of work support relies on processing personal and intimate data from users and thus, require the willingness to share these data. As a first step towards building SPWSS, we investigate the data perspective of such systems. In doing so, we present an architecture of connected devices. Since the willingness of users to share their personal data is a crucial prerequisite for such sys-tems, we furthermore present results from an empirical investigation concerning the willingness of users to share selected data for specific purposes.

    HCI-Patterns für kollaborative Unternehmensmodellierung am Multi-Touch-Tisch
    (Modellierung 2020, 2020) Gutschmidt, Anne; Sauer, Valentina; Sandkuhl, Kurt
    Sollen Unternehmensmodelle kollaborativ durch die Stakeholder selbst erstellt werden, bieten sich insbesondere Multi-Touch-Tische (MTT) als nützliches digitales Werkzeug an. Für die Gestaltung von Software und insbesondere deren Benutzungsoberfläche sollte auf bewährte Lösungen - sogenannte HCI-Patterns - zurückgegriffen werden. Das von uns betrachtete Anwendungsfeld bringt jedoch besondere Anforderungen an die Modellierungssoftware für einen Multi-Touch-Tisch mit sich. In einer Studie, angelehnt an die Repertory-Grid-Technik, ließen wir acht Modellierungsexperten, die wir in drei Gruppen einteilten, vier verschiedene Modellierungsprogramme vergleichen und ermittelten so wesentliche Merkmale von Modellierungsoftware für MTT. Diese haben wir mit Katalogen von HCI-Patterns abgeglichen und die Patterns selektiert, die am besten auf die von den Experten geäußerten Bedürfnisse passen.
