    As a result of growing complexities in business processes, information systems, and the technical infrastructure, a key challenge for enterprise architecture management (EAM) is to guide stakeholders from different hierarchical levels with heterogeneous concerns. EA deliverables, such as models or frameworks, are often highly comprehensive and standardized. However, these can hardly be applied without greater adaption. Although the literature selectively covers approaches for tailoring EA deliverables closer to the concerns of affected stakeholders, these approaches are often vague or not very differentiated. In the paper at hand, we aim at introducing a stakeholder perspective to EAM research that considers stakeholder concerns on EAM across hierarchical levels. To this end, we conduct a case study: Our results show homogenous concerns among stakeholders on EA deliverables. In turn, we found different concerns on the role of EAM in applying these deliverables, dependent on the hierarchical level of stakeholders. These findings stress the necessity for a more differentiated understanding of stakeholder concerns on EAM. Finally, we discuss the implications of our findings for an exemplary EAM approach.

    Introducing a Coordination Perspective to Enterprise Architecture Management Research
    (IEEE Computer Society, 2017-10-10) ; ; ;
    Hallé, Sylvain
    ;
    Dijkman, Remco
    Enterprise Architecture Management (EAM) is a prominent discipline for purposefully guiding the complex, co-evolutionary business-IT relationships in organizations. Means to realize such guidance are, among others, mechanisms to coordinate heterogeneous and potentially conflicting stakeholder concerns. Yet, organizations face challenges to successfully leverage their EAM initiatives, often as a result of coordination mechanisms that only reach specific stakeholders or selected contexts. In the paper at hand, we aim at introducing coordination as a research lens for analyzing and designing EAM approaches. To this end, we substantiate the abstract notion of coordination through its underlying formal and informal mechanisms, which are implemented by artifacts, as well as through artifact modalities in an analysis framework. For illustrative purposes, we apply the developed analysis framework to The Open Group Architecture Framework (TOGAF). We find informal mechanisms (lateral relations, communication, and socialization) comparably underrepresented, which limits not only coordination effects but may also limit the success of the overall EAM approach. Our findings call for an extended and more comprehensive perspective on coordination in EAM, motivating the complementarity of informal mechanisms as an avenue for future research.

    Dynamics of Control Mechanisms in Enterprise Architecture Management: A Sensemaking Perspective
    Enterprise architecture management (EAM) has long been considered a governance means to impose enterprise-wide objectives to local information systems development projects. This perspective on EAM inevitably brings about formal control mechanisms with the aim of enforcing enterprise-wide objectives in a top-down fashion. This study takes a complementary perspective by investigating the portfolio of control mechanisms with and beyond formal control mechanisms. We examine control portfolios and their dynamics over time. We employ control theory to capture the portfolio of control mechanisms, and an organizational sensemaking perspective, to capture its dynamics. The longitudinal analysis of a financial service company over a decade reveals that EAM’s portfolio of control mechanisms emerges in an ongoing sensemaking process. In this process, various stakeholders continuously interpret cues in their environment and take actions in response to these cues. Further, we demonstrate that control portfolios are constantly (re)configured, through different combinations of formal and informal mechanisms.

    A Learning Perspective on Enterprise Architecture Management
    (Association for Information Systems, 2016-12-11) ; ; ;
    Enterprise architecture management (EAM) has long been propagated in research and practice as an approach for keeping local information systems projects in line with enterprise-wide, long-term objectives. EAM literature predominantly promotes strictly governed and centralized coordination mechanisms to achieve the promised alignment contributions. Notwithstanding the increasing maturity levels in practice, organizations still struggle with the successful establishment of EAM, mainly due to the inherent challenges of a firmly centralized approach in complex organizational settings. This study opts for cooperative learning as a theoretical lens to afford a distinctive, non-centralized conceptualization of EAM. We empirically demonstrate EAM as a stage-wise learning process in which knowledge acquisition and cooperative interactions among individuals contribute to project performance on the local level. Projects that benefit from this particular learning process, in turn, are found to significantly leverage enterprise-wide performance.

    Design Science Research in Business Innovation
    Business innovation research either aims at describing and understanding business innovation phenomena, or at changing a present world it into a better or preferred one. This article discusses the later approach, which has the goal to contribute new theories for design and action. Such design theories comprise useful business innovation artifacts such as products and services, business processes, or business models. In this article we advocate the opportunities that design-oriented business innovation research offers to researchers and to practice, we provide an overview on the relations of design-oriented business innovation research to other research paradigms in business research, we summarize and link to state-of-the-art guidance for conducting design-oriented business innovation research, and we present exemplars of design-oriented business innovation research and discuss their positioning in the field of design-oriented research.

    Success Factors for Federated Enterprise Architecture Model Management

    Recent approaches for managing Enterprise Architecture (EA) models provide technical systems to procure information from existing repositories within the application landscape of an organization. Beyond technical solutions, social factors are of utmost importance to implement a successful EA initiative. Institutional theory has for example been employed to understand crucial factors for realizing EA management (EAM) benefits through architectural thinking. Yet, it remains unclear how these social factors influence a federated approach for EA model management. Based on a socio-technical systems perspective, we investigate success factors for Federated EA Model Management (FEAMM) by conducting qualitative interviews with industry experts. Our findings suggest that success factors for FEAMM are related to the model sources, modeling instruments, and model integration aspects from a technical perspective as well as to organizational grounding, governance, enforcement, efficiency, goal alignment, and trust from a social perspective.

    Simulation-Based Research in Information Systems: Epistemic Implications and a Review of the Status Quo
    Simulations 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.

    Untangling EA’s Long Path of Becoming a Partner for Business Transformation: The Case of Swiss Federal Railways
    (IEEE Computer Society, 2016-09-05) ; ; ;
    Rytz, Bernhard

    We analyze the enterprise architecture management (EAM) ‘journey’ of the Swiss Federal Railways over the last twenty years. Fundamental organizational changes were matched by shifts of EAM’s focus from advocating an enterprise-wide perspective over developing the enterprise architecture toolbox to establishing business transformation support. Beyond maturity considerations, insights from this longitudinal case study can be gained from an institutional perspective, i.e., by describing the EAM journey not only as a process of establishing the EAM function, but also as a process that extends EAM effects beyond the boundaries of IT. We identify four principles that guided this process: (1) Consistency of norms and values (2) Focus on reinventing rather than maturing (3) Picking the right EAM ‘battles’, and (4) Playing on EAM’s holistic perspective.

    Architectural coordination of enterprise transformation (ACET) integrates and aggregates local information and provides different viewpoints, such as financial, structural, or skill perspectives to the respective stakeholder groups, with the aim of creating a consensus and shared understanding of an enterprise transformation among the stakeholders. Its core purpose is to inform decision-makers with both local and enterprise-wide concerns so that the overall transformation goals can be successfully pursued, i.e. reducing inconsistencies and including local decisions in the overarching goals. This book consists of three major parts, framed by an introduction and a summary. To enable readers to gain a better understanding of the issues involved in real-world enterprise transformations as well as the possible role of architectural coordination and the associated challenges, Part I provides an analysis of status quo of corporate ACET practice. Part II then continues with an exploration of the challenges facing ACET from a theoretical perspective. Based on these challenges, Part III then presents a collection of components for a possible design theory for ACET. Instead of an integrated method, this collection of components constitutes method fragments that can be arranged in different ways depending on the perspective taken, the actual enterprise architecture management approach, the enterprise transformation type and the transformation’s context.

    The discipline of enterprise architecture (EA) has become well-established in many organizations and is continuously discussed in academic literature. However, EA's effectiveness beyond IT is limited. The paradigm of architectural thinking aims at reaching the 90% of an organization that is not related to IT. The paper contrasts the abstract definitions of architectural thinking with empirical case study data. We find that practice has developed implementations of these abstract definitions. However, we also find new characteristics of architectural thinking that have not yet been discussed in literature. Specifically, these are the role of decisions and the role of formal governance mechanisms.
