    How to Preserve Agility in Service Oriented Architectures - An Explorative Analysis
    (Ges. für Informatik, 2010) ;
    Although companies introduced enterprise application integration (EAI) a couple of years ago, the complexity of corporate application landscapes is ever increasing. The current wave of technology being introduced into these application landscapes are service oriented architectures (SOA). Not unlike EAI before the introduction of these technologies is associated with re-use of software components and reaping cost cutting potentials. But when looking at the still increasing complexity of application landscapes following the introduction of SOA, the re-use and cost cutting arguments lead to disappointment. However, SOA offers a great potential to increase corporate agility. In order to gain and preserve corporate agility it is necessary to explicitly manage enterprise architecture. This paper discusses the problems of re-use and cost cutting expectations in SOA and contrasts them with the potentials related to make sustainable contributions to corporate agility. Structures, processes, and instruments to realize these potentials are discussed with reference to a literature review as well as to selected case studies.

    On the Conceptualization of Information Systems as Socio-Technical Phenomena in Simulation-Based Research
    (Association for Information Systems, 2015-12-13) ; ;
    Information Systems (IS) are specified as complex socio-technical systems that display dynamic and emergent behaviors. Simulation-based studies provide a useful tool for analyzing such systems; however, the current presence and impact of simulation-based IS studies is limited. The socio-technical interactions and inherent dynamics of information systems make the development of IS simulations attractive, but challenging. Building simulations in this context requires both accurate conceptualizations of the underlying socio-technical systems as well as a sound transfer of these conceptualizations into simulation models. This study proposes an analysis framework that conjointly captures both the socio-technical system models as well as the derived simulation models. This allows for a critical assessment of the status quo of the extant simulation-based IS research. The identified relations are analyzed and seven propositions are derived, which provide guidance for prospective simulation-based research.

    Visualizing and Measuring Enterprise Application Architecture: An Exploratory Telecom Case

    We test a method for visualizing and measuring enterprise application architectures. The method was designed and previously used to reveal the hidden internal architectural structure of software applications. The focus of this paper is to test if it can also uncover new facts about the applications and their relationships in an enterprise architecture, i.e., if the method can reveal the hidden external structure between software applications. Our test uses data from a large international telecom company. In total, we analyzed 103 applications and 243 dependencies. Results show that the enterprise application structure can be classified as a core-periphery architecture with a propagation cost of 25%, core size of 34%, and architecture flow through of 64%. These findings suggest that the method could be effective in uncovering the hidden structure of an enterprise application architecture.

    Business Models in the Data Economy: A Case Study from the Business Partner Data Domain
    (Universität Leipzig, 2013-02-27) ; ; ;
    Franczyk, Bogdan
    Data management seems to experience a renaissance today. One particular trend in the so-called data economy has been the emergence of business models based on high-quality data. In this context, the paper examines the business partner data domain. Business partner data comprises unique identifiers, unambiguous names, or subsidiary information of business partners. The paper explores as to how and why business models of business partner data providers differ. Based on a study of six cases, the paper identifies three different business model patterns. A resource based view is used to explore the details of these patterns. Furthermore, the paper develops a set of propositions with regard to the establishment and evolution of certain business models. Furthermore, the paper discusses a market transformation from a traditional value chain toward a value network paradigm-a change which would seriously threaten the business models of established data providers such as Dun Bradstreet.

    Crossing the line: overcoming knowledge boundaries in enterprise transformation
    Enterprise 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.

    Architectural Coordination of Enterprise Transformation
    (Springer, 2017)

    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.

    Criteria of Progress for Information Systems Design Theories
    (Springer, 2011-03-01) ;
    Fischer, Christian
    According to Kuhn, science and progress are strongly interrelated. In this paper, we define criteria of progress for design theories. A broad analysis of the literature on information systems design science reveals that there is no consensus on the criteria of progress for design theories. We therefore analyze different concepts of progress for natural science theories. Based on well-founded criteria stemming from the philosophy of science and referring to natural science theories, we develop a set of criteria of progress for design theories. In summary, our analysis results in six criteria of progress for design theories: A design theory is partially progressive compared to another if it is ceteris paribus (1) more useful, (2) internally more consistent, (3) externally more consistent, (4) more general, (5) simpler, or (6) more fruitful of further research. Although the measurement of these criteria is not the focus of this paper, the problem of measurement cannot be totally neglected. We therefore discuss different methods for measuring the criteria based on different concepts of truth: the correspondence theory of truth, the coherence theory of truth, and the consensus theory of truth. We finally show the applicability of the criteria with an example.

    On the role of complexity for guiding enterprise transformations
    (Springer, 2015-06-15) ; ; ;
    Aveiro, David
    ;
    Pergl, Robert
    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.

    A Major Transformation at a Global Insurance Company
    (Springer International Publishing - Springer, 2017) ; ; ;
    Proper, Henderik A.
    ;
    In this chapter we report on the case of a globally operating insurance company that has leveraged enterprise architecture management to support business transformations. In order to do so, the company has developed enterprise architecture management capabilities that help the business structuring the business transformation particularly in the early stages before handing over respective responsibilities to more specialized corporate functions later on. This case is interesting for understanding ACET because it is one of the rare cases where enterprise architecture management truly bridges the business–IT gap.
