- ZeitschriftenartikelContradictions and Interventions in Health IS(Business & Information Systems Engineering: Vol. 63, No. 6, 2021) Weeger, Andy; Wagner, Heinz-Theo; Gewald, Heiko; Weitzel, TimThe study analyzes data collected in two case studies in the healthcare industry, which is characterized by a variety of social and technical elements forming an activity system where all elements interact with each other. The findings indicate that many problems emerging during the implementation of a health information system can be traced back to contradictions between elements of the activity systems that are created or amplified by the new IS. The authors find that some contradictions are latent and become salient when introducing a new IS, while other contradictions are (unintentionally) newly created. Also, the study shows that contradictions are more complex than hitherto assumed and often concern more than two elements of a healthcare activity system. In a similar vein, effective interventions geared toward countering these contradictions are found to account for additional complexity while not always achieving their goal. Drawing on activity theory, the authors develop a framework to coherently synthesize the findings. The study can help increase the understanding of the IS’s role within an activity system and help guide IS implementation projects aimed at avoiding unintended consequences.
- TextdokumentIntegrating DevOps within IT Organizations- Key Pattern of a Case Study(Projektmanagement und Vorgehensmodelle 2018 - Der Einfluss der Digitalisierung auf Projektmanagementmethoden und Entwicklungsprozesse, 2018) Wiedemann, Anna; Wiesche, Manuel; Gewald, Heiko; Kremar, HelmutTeam-oriented, service-centric approaches for software delivery processes are becoming more and more popular. One approach that has appeared on the scene in the last decade is called DevOps. To date, little is known about how cross-functional product-oriented teams can be integrated within traditional companies. Hence, we decided to contact organizations that have already started implementing DevOps-specific processes. We talked to 34 people from 10 organizations and derived new insights into the area of DevOps. We show that there are different patterns by which DevOps can be integrated within companies—e.g. with the help of platform-oriented teams. Further, we find that teams are organized in different setups and use extended workbenches for collaboration. Our case study highlights that for successful DevOps implementation, it is important to convince every stakeholder and to work with agile coaches who can foster awareness for the necessity of DevOps
- ZeitschriftenartikelThe 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, HelmutDigitalization 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.
