    While there is a general agreement on the need for tools, which guide the evolution of complex organizational systems, and while there already exists a wealth of tools and approaches for the measurement and management of complexity, it seems that in practice these approaches often fail to achieve the desired impact during transformation processes. Based on focus group data and based on related literature, we analyze the factors that hinder current complexity management systems from guiding enterprise transformations and contribute a set of design principles, which address these factors. In particular, it is important to be aware of the context, to use a consistent ontology, to pay attention to visualization and to raise awareness and support.

    In this paper we explore the role of pressure for the use of enterprise architecture (EA) artifact. Based on a quantitative dataset on EA artifacts and enterprise architecture management (EAM) benefits, we specifically explore the relationships between the use intensity of EA artifacts, pressure to use these artifacts, and EAM benefit realization. Focusing on the role of pressure to use EA artifacts, we conceptualize four different classes of artifacts based on (1) how intensively they are used in practice and (2) to what degree pressure increases the use intensity. Our results suggest that each class (EA shelf-warmers, EA superstars, EA annoyances, EA pressure beneficiaries) requires different approaches to foster its use intensity. We derive pressure-based and pressure-free approaches for each class aiming at increasing the use intensity of EA artifacts. Additionally we identify the EA artifacts that have the highest impact on EAM utility (e.g., map of company goals, target process map, target application landscape, and the principle ease of use). We discuss management implications accordingly. Keywords-enterprise architecture, use, utility, pressure, EA management

    Enterprise transformations (ET) fail in many cases or do not accomplish the expected goals. Enterprise architecture management (EAM) is often considered to be an appropriate means to tackle this problem by providing information that is relevant to ET managers. Therefore, we analyze, which types of information provided during an ET contributes to its success. In addition we discuss if EAM can appropriately support ETs by providing relevant information. The results show that value can be provided to ET management when business-related information on a detailed level is offered. Examples are business requirements, business functions, or qualitative measures. We find information that can be provided by EAM to be an important success factor for ETs.

    Enterprise architecture management (EAM) in organizations often requires coping with conflicts between long-term enterprise-wide goals and short-term goals of local decision-makers. We argue that these goal conflicts are similar to the goal conflicts that occur in public goods dilemmas: people are faced with a choice between an option (a) with a high collective benefit for a group of people and a low individual benefit, and another option (b) with a low collective benefit and a high individual benefit. Building on institutional theory, we hypothesize how different combinations of institutional pressures (coercive, normative, and mimetic) affect decision makers’ behavior in such conflictive situations. We conduct a set of experiments for testing our hypotheses on cooperative behavior in a delayed-reward public goods dilemma. As preliminary results, we find that normative and mimetic pressures enhance cooperative behavior. Coercive pressure, however, may have detrimental effects in settings that normative and mimetic pressures are disregarded. In future work, we plan to transfer the abstract experimental design of an onlinelab experiment into a field experiment setting and thus into the real-world context of EAM.

    The Institutional Logic of Harmonization: Local vs. Global Perspectives

    Perspectives in organizations differ to which extent information systems (IS) should be tailored towards local (e.g., business unit) needs or toward organi-zation-wide, global goals (e.g., synergies, integration). For contributing to overall IS performance success, the harmonization of different perspectives becomes essential. While many scholars have highlighted the role of IS management approaches, institutional studies argue that harmonization is not solely the result of managerial action, but a consequence of institutional pressures that guide organizational decision-making. In the paper at hand, we follow the call for adopting institutional theory on the intra-organizational level of analysis and study the logic of attaining harmoniza-tion along institutional pressures. By means of a revelatory case study, we find harmonization attained in a dynamic interplay between different institu-tional pressures. Mimetic pressures influence normative pressures, which in turn influence coercive pressures. Our findings as well as our implications for enterprise engineering guide prospective research in studying the attain-ment of harmonization through an institutional lens.

    Information systems (IS) research has long been promoting the necessity of aligning local IS investments in organizations with their enterprise-wide objectives. One of the prominent means to realize such an alignment are mechanisms that coordinate various stakeholders in different organizational entities. Despite its prominent origins and manifold translations from organization science (OS), there is no coherent body of coordination theory. The research at hand con-ducts a literature review of coordination mechanisms to offer a more coherent understanding of coordination for prospective IS research. To this end and structured in eight categories of mechanisms, we contrast a reflection of coordination in OS and IS research. We also discuss how IS studies follow and complement OS research, outlining implications for future research.
