PublicationService-Oriented Business-IT Alignment: A SOA Governance Model(The International Association for Information, Culture, Human and Industry Technology (AICIT), )The concept of Service Oriented Architecture (SOA) has had a significant impact not only on software engineering but on the analysis of an organization’s business layer as well. It contributes to developing information systems that are compatible with the needs of agile organizations. This fact brings us to investigate the new approach of Business-IT Alignment (BITA) by utilizing SOA features. In this paper we will first examine the importance of SOA in both business and IT perspectives. We will proceed by showing the SOA governance as a roadmap for bringing the concept of SOA in the context of BITA (as one of the major IT challenges). Finally, we will propose a SOA Governance Model (SOAGM) that should help aligning IT investments with business strategies.

PublicationGovernance Mechanisms in Digital Platform Ecosystems: Addressing the Generativity-Control TensionDigital platform owners repeatedly face paradoxical design decisions with regard to their platforms’ generativity and control, requiring them to facilitate co-innovation whilst simultaneously retaining control over third-party complementors. To address this challenge, platform owners deploy a variety of governance mechanisms. However, researchers and practitioners currently lack a coherent understanding of what major governance mechanisms platform owners rely on to simultaneously foster generativity and control. Conducting a structured literature review, we connect the fragmented academic discourse on governance mechanisms with each aspect of the generativity-control tension. Next to providing avenues for prospective digital platform research, we elaborate on the double-sidedness of governance mechanisms in fostering both generativity and control.

PublicationThe Mechanics of Enterprise Architecture Principles(Assoc. of Information Systems, 2021-09-05)Inspired by the city planning metaphor, enterprise architecture (EA) has gained considerable attention from academia and industry for systematically planning an IT landscape. Since EA is a relatively young discipline, a great deal of its work focuses on architecture representations (descriptive EA) that conceptualize the different architecture layers, their components, and relationships. Beyond architecture representations, EA should comprise principles that guide architecture design and evolution toward predefined value and outcomes (prescriptive EA). However, research on EA principles is still very limited. Notwithstanding the increasing consensus regarding the role and definition of EA principles, the limited publications neither discuss what can be considered suitable principles nor explain how they can be turned into effective means to achieve expected EA outcomes. This study seeks to strengthen the extant theoretical core of EA by investigating EA principles through a mixed methods research design comprising a literature review, an expert study, and three case studies. The first contribution of this study is that it sheds light on the ambiguous interpretation of EA principles in the extant research by ontologically distinguishing between principles and nonprinciples, as well as deriving a set of suitable EA (meta)principles. The second contribution connects the nascent academic discourse on EA principles to studies on EA value and outcomes. This study conceptualizes the “mechanics” of EA principles as a value creation process, where EA principles shape architecture design and guide its evolution and thereby realize EA outcomes. Consequently, this study brings the underserved, prescriptive aspect of EA to the fore and helps enrich its theoretical foundations.

PublicationSimulation-Based Research in Information Systems: Epistemic Implications and a Review of the Status QuoSimulations provide a useful methodological approach for studying the behavior of complex socio-technical information systems (IS), in which humans and IT artifacts interact to process information. However, the use of simulations is relatively new in IS research and the current presence and impact of simulation-based studies is still limited. Furthermore, simulation-based research is quite different from other approaches, making it difficult to position and evaluate it adequately. Therefore, this paper first analyses the epistemic particularities of simulation-based IS research. Based on this analysis, a structured literature review of the status quo of simulation-based IS research was conducted, to understand how IS scholars currently employ simulation. A comparison of the epistemic particularities of simulation-based research with its status quo in IS literature allows to critically examine epistemic inferences in the respective research process. The results provide guidance for prospective simulation-based IS research through discussing the theory-based derivation of simulation models, as well as different simulation techniques, validation techniques, and simulation uses.Type:Journal:Volume:Issue:
