PublicationCrossing the line: overcoming knowledge boundaries in enterprise transformationEnterprise transformations are fundamental changes in an organization. Such changes typically affect different stakeholder groups (e.g., program managers, business managers) that exhibit a significant diversity regarding their members' knowledge, goals, and underlying assumptions. Yet, creating shared understanding among diverse stakeholder groups in transformations is a main antecedent for success. In this paper, we analyze which properties of enterprise architecture models contribute to syntactic, semantic, and pragmatic capacities and thereby help to create shared understanding among stakeholder groups involved in enterprise transformation. We assess the differences among stakeholder groups through the lens of knowledge boundaries, and enterprise architecture models through the lens of boundary objects. We develop and empirically test a research model that describes which boundary object properties are required to overcome three progressively complex knowledge boundaries-syntactic, semantic, and pragmatic. Our findings show which boundary object properties contribute to a respective capacity needed to overcome each of the three knowledge boundaries. Specifically, we find that for (1) a syntactic capacity, concrete and modular EA models are helpful; (2) a semantic capacity, visual EA model properties are relevant, and (3) a pragmatic capacity, broad stakeholder participation is conductive.Type:Journal:Volume:Issue:

PublicationUnderstanding Continuous Use of Business Intelligence Systems: A Mixed Methods InvestigationBusiness intelligence (BI) systems play an important role in organizations' decision-making processes. The existing literature has long focused on the continuous use of information systems (IS). However, the specificities of BI systems such as voluntary use, long-term return of investments, heterogeneity of their use cases, and innovative rather than routine use in such systems motivate our investigating continuous use in the specific context of BI systems. To theorize continuous use of BI systems, we investigate the influencing factors and their interactions. By means of an exploratory and confirmatory mixed-methods research design that comprises a literature review, a single-case study, and a survey, we integrate the identified factors and hypothesize their influence on the continuous use of BI systems in a research model. We test the research model following a partial least squares (PLS) approach to structural equation modeling (SEM). The paper makes two primary contributions: 1) it confirms certain well-established constructs and relations in the specific context of BI systems, which are generally theorized for the continuous use of IS, and 2) it introduces either new constructs or new relations through the given investigation in the context of BI systems. Future studies can test these new constructs and relations as potential input for theorizing general IS continuous use.Type:Journal:Volume:Issue:

PublicationFail Early, Fail Often: Towards Coherent Feedback Loops in Design Science Research EvaluationWe propose feedback loops that increase the coherence between evaluation activities in a design science research (DSR) process. While several scholars have proposed DSR cycles with frequent evaluation activities to provide timely feedback on design activities, the question of how to ensure coherence between these activities has remained largely unaddressed. Yet, coherence is essential to claim validity not only for the DSR artifact, but also for the DSR process. Based on a review of existing DSR literature, we propose an approach that ensures coherence between initial problem definition and final evaluation activities by explicating the notion of relevance underlying the DSR project, and between design and construction activities by creating situational design specifications.We exemplarily apply our approach to an ongoing DSR project. We conclude with a research agenda, where we build on the recent debate on generalizability in information systems to identify six fruitful avenues for further research.
