    Legal Compatibility as a Characteristic of Sociotechnical Systems
    (Business & Information Systems Engineering: Vol. 57, No. 2, 2015) Hoffmann, Axel; Schulz, Thomas; Zirfas, Julia; Hoffmann, Holger; Roßnagel, Alexander; Leimeister, Jan Marco
    Legal compatibility as a characteristic of sociotechnical systems aims at the greatest possible compliance with higher-order legal goals for minimizing social risks of technical systems and extends legality, which refers to the prevention of lawlessness. The paper analyzes the criteria for legal compatibility by reviewing specifications of legally compatible systems and shows goals and resulting requirements to foster legal compatibility. These comprise the following areas: avoiding personal reference in data, ensuring information security, enabling freedom of decision, increasing transparency, ensuring traceability, and increasing usability, whereby traceability and the avoidance of personal reference pursue conflicting goals. The presentation of the goals including their dependencies, relationships, and conflicts in form of standardized requirements explains legal compatibility and summarizes the requirements necessary for the development of legally compatible systems.

    The Negative Effects of Institutional Logic Multiplicity on Service Platforms in Intermodal Mobility Ecosystems
    (Business & Information Systems Engineering: Vol. 62, No. 5, 2020) Schulz, Thomas; Böhm, Markus; Gewald, Heiko; Celik, Zehra; Krcmar, Helmut
    Digitalization is changing the mobility sector. Companies have developed entirely new mobility services, and mobility services with pre-digital roots, such as ride-sharing and public transport, have leveraged digitalization to become more convenient to use. Nevertheless, private car use remains the dominant mode of transport in most developed countries, leading to problems such as delays due to traffic congestion, insufficient parking spaces, as well as noise and air pollution. Emerging intermodal mobility ecosystems take advantage of digital advances in mobility services by providing individual, dynamic and context-aware combinations of different mobility services to simplify door-to-door mobility and contribute to the reduction of private car use. However, the service platforms are limited in terms of functional range, for example they may lack integrated ticketing and rely on static data, which makes intermodal mobility inconvenient. This article adopts the service-dominant logic perspective to analyze service ecosystems for intermodal mobility and their service provision. Drawing on traditional institutional literature, the authors question the assumption that service logic is dominant for all actors of a service ecosystem. By applying activity theory, the article illustrates how an institutional logic multiplicity among actors can negatively affect the functional range of service platforms. The results of a qualitative study in Germany show that, in particular, the state logic of some actors, which is characterized by the obligation to provide mobility, impairs the quality of service platforms in supporting citizens in intermodal mobility.

    Vorschläge zur rechtskonformen Gestaltung selbst-adaptiver Anwendungen
    (INFORMATIK 2011 – Informatik schafft Communities, 2011) Schulz, Thomas; Skistims, Hendrik; Zirfas, Julia; Comes, Diana; Evers, Christoph
    Durch neue Paradigmen wie Ubiquitous Computing ergeben sich neue Möglichkeiten und Anwendungsgebiete für die Informationstechnik, angefangen bei einfachen Alltagsaufgaben wie dem Einkaufen bis hin zur Planung und Durchführung von Terminen oder Veranstaltungen. Dieser Beitrag beschäftigt sich mit der Frage, inwiefern das grundgesetzlich garantierte Persönlichkeitsrecht durch neue Techniken und technikorientierte Paradigmen beeinflusst wird und welche Möglichkeiten es gibt, diese Beeinflussung bei der Technikentwicklung zu berücksichtigen. Bei dieser Analyse liegt der Schwerpunkt auf der Grundfunktionalität der Adaption sowie der Entdeckung und Integration externer Dienste als elementare Bestandteile von ubiquitären Systemen. Ausgangspunkt für die rechtliche Analyse ist die selbst-adaptive und kontextsensitive Anwendung „Meet-U“.
