    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.

    Institutionalization and the Effectiveness of Enterprise Architecture Management

    Enterprise Architecture Management (EAM) has become a prominent discipline for managing increasingly complex Business/IT relationships in organizations. The more tangible aspects of EAM like modeling, planning, principles or governance structures are widely discussed and understood. However, institutionalizing EAM in an organization remains a challenging issue. Therefore, actually realized EAM benefits can be observed to vary widely across organizations. To address these issues, we take an institutional theory perspective and propose nine hypotheses which are tested based on quantitative empirical data. Our findings confirm seven institutional factors as antecedents for institutionalizing EAM in terms of positive stakeholder response, EA consistency and a realization of EAM benefits for the organization. Our research supports the understanding of the relevant phenomenon of institutionalization of EAM as a rather practice-driven discipline, where theoretical foundations as well as research into non-technical issues are limited so far.

    An Institutional Framework for Analyzing Organizational Responses to the Establishment of Architectural Transformation
    (Association for Information Systems, 2012-06-11)

    The need for constant transformation of enterprises is omnipresent. A discipline that has been proposed to support the coordination of enterprise transformation is Enterprise Architecture Management (EAM) which has grown to a mature discipline in academia and practice. However, it can be observed in practice that it still is a challenge to introduce such an architectural coordination approach for supporting enterprise transformation. This may be due to the reason that the institutional context of EAM is only little understood, that is, the interplay between the pressures EAM exerts on the organisation and the response strategies of this organisation. The paper reviews existing work on institutional theory and confirms by means of a case study that the institutional factors of cause, constituents, content, control, and context are not only relevant for EAM but may be consistently linked to response strategies of acquiesce, compromise, avoid, defy, and manipulate. Moreover the case study implies to add additional institutional factors for EAM, namely trust and participation.

    Facilitating Enterprise Transformation Through Legitimacy - An Institutional Perspective

    Much research has been conducted in order to design sophisticated enterprise transformation (ET) methods, for instance in terms of enterprise architecture management. However, only little attention has been paid to the factors that, to some extent independent of a method's sophistication, exert pressure on a transformation approach's desirability, appropriateness, and acceptance. Grounded in institutional theory, this paper structures and exemplifies design factors that should be obeyed in order to build and anchor an effective enterprise transformation approach in an intra-organizational context. Specifically we found the factor of legitimacy to be crucial for successful ET. Strategies for gaining legitimacy are discussed accordingly. Overall, this paper's institutional perspective contributes to better understand and design ET approaches.

    While elaborate enterprise architecture management (EAM) methods and models are at architects' disposal, it remains an observable and critical challenge to actually anchor, i.e. institutionalize, EAM in the organization and among non-architects. Based on previous work outlining design factors for EAM in light of institutional theory, this work discusses the theoretical grounding of respective design factors and proposes measurement items for assessing the institutionalization of EAM in organizations. The work identifies measurement items for the factors legitimacy, efficiency, stakeholder multiplicity, organizational grounding, goal consistency, content creation, diffusion and trust, contributing to evaluate and inform EAM design from several, partially new perspectives.

    In this Chapter we present a reference framework, more specifically a catalogue of capabilities, needed for doing ACET. As such, it also provides guidance on which elements/artefacts of enterprise architecture can be used to support which aspects of enterprise architecture. For architects, it shows where their services might generate value, if requested. For transformation managers, it provides a “capability catalogue”, describing for which parts of enterprise architecture they may seek advice from the enterprise architects. The framework as a whole provides a structure for the solution components that addresses the challenges as presented in Part II, and it comprises of the perspectives of strategy, value and risk, design, implementation, and change. The capabilities of all the perspectives together support transformation management, which is concerned with the management tasks at the overall transformation level, and with the architectural coordination function, which forms an umbrella function of integrating the individual perspectives into a consistent whole.
