PublicationManagement of Enterprise-Wide Information Systems(Springer, 2021)This article offers a short retrospective on the research streams about enterprise-wide IS management at the chair of Robert Winter. Both research project streams on analytical integration (data warehousing, information integration etc.) and transactional integration (application integration, enterprise architecture, transformation management) reside in the same understanding of the extended application landscape developed by Robert Winter.Type: book section

PublicationDesign Pattern as a Bridge Between Problem-Space and Solution-Space(Springer, 2021)
;Dickhaut, ErnestineDesigning novel technologies provide challenges to developers. To support developers in designing these technologies, design knowledge must be codified and made applicable for the future. In systems development, design patterns provide proven solutions to solving recurring problems. They contain templates for describing design information, often in tabular form, and are established tools for making complex knowledge accessible and applicable. Design patterns play a critical role in both practice and research in finding potential solutions. For researchers, patterns can provide a method for codifying design knowledge for future research. For practitioners, design patterns provide established solutions to recurring problems. By applying them in a particular context, the pattern represents elements of both the problem-space and the solution-space, providing an opportunity to bridge the gap between the two spaces. Due to the abstraction of design patterns, they can be used for different application scenarios. The preparation of the design knowledge in the design pattern is a critical step to support the user in the best possible way, that determines the usefulness of the pattern. -
PublicationEnterprise Architecture as a Public Goods Dilemma: An Experimental Approach(Springer, 2020)
;Aveiro, David ;Guizzardi, GiancarloBorbinha, JoseEnterprise 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.Type: book sectionVolume: 374Scopus© Citations 2 -

PublicationThe Institutional Logic of Harmonization: Local vs. Global Perspectives(Springer Nature, 2019)
;Aveiro, David ;Guizzardi, Giancarlo ;Guerreiro, SérgioGuédria, WidedPerspectives 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.Type: book sectionVolume: 334Scopus© Citations 5 -
PublicationTransformation Intelligence Capability Catalogue(Springer International Publishing - Springer, 2017)
;Proper, Henderik A.de Kinderen, SybrenIn 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.Type: book sectionVolume: 1st edition 2017Scopus© Citations 2 -
PublicationA Literature Review of Coordination Mechanisms: Contrasting Organization Science and Information Systems Perspectives(Springer Nature, 2017)
;Aveiro, David ;Pergl, Robert ;Guizzardi, Giancarlo ;Almeida, Jose ;Magalhães, RodrigoLekkerkerk, HansInformation 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.Type: book sectionVolume: 284Scopus© Citations 2 -
PublicationA Major Transformation at a Global Insurance Company(Springer International Publishing - Springer, 2017)
;Proper, Henderik A.de Kinderen, SybrenIn 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.Type: book sectionVolume: 1st edition 2017 -
PublicationExtending CCM4DSR for Collaborative Diagnosis of Socio-Technical Problems(Springer, 2017-05-23)
;Maedche, Alexander ;Brocke, Jan vomHevner, AlanThe identification of a problem, its causes and its consequences are integral parts of designing useful solutions in Design Science Research (DSR). Many problems addressed in DSR are of a socio-technical nature, and they are collaboratively solved in multidisciplinary teams. Accordingly, analysis techniques are needed which integrate diverse perspectives of problem analysis. Colored Cognitive Mapping for DSR (CCM4DSR) is such a technique. By applying CCM4DSR to an exemplary socio-technical problem, this paper reports on observed challenges and offers four extensions to CCM4DSR. These extensions provide guidance in adequately stating the problem, considering path dependencies, explicating different stakeholder perspectives, and integrating dif-ferent perspectives through a comprehensive process.Type: book sectionIssue: 10243Scopus© Citations 7 -
PublicationSituational Adaptations of ACET(Springer, 2017)
;Proper, Henderik A.de Kinderen, SybrenIn this chapter we address the fact that not all ACET problems are equal, and ACET solutions therefore need to be configured to address the specifics of the respective ACET problem. We approach this configuration problem by the means of situational method engineering. We find that the two most important differences of ACET problem situations result from the enterprise architecture management approach used, and the respective type of the transformation. We therefore present classifications for enterprise architecture management and enterprise transformation, and propose an appropriate ACET problem situation matrix. We finally demonstrate how ACET solutions are configured to a given problem situation.Type: book sectionScopus© Citations 1
