    2nd european workshop on patterns for enterprise architecture management (PEAM2010)
    (Software Engineering 2010, 2010) Matthes, Florian; Buckl, Sabine; Schweda, Christian M.
    Enterprise architecture (EA) and the holistic management thereof are topics of ongoing interest from practitioners, standardization bodies, and researchers. Not surprisingly, a large number of different approaches, frameworks, and guidelines for EA management have been developed in the last years, all targeting different aspects of the architecture and the corresponding management function, respectively. Therefore, a multitude of linguistic communities emerged around the subject, each using its distinct terminology as well as forms of presenting the approaches, frameworks, and guidelines. In this light, especially practitioners may find it increasingly complex to contribute their experience to the body of knowledge in the field of EA management. EA management patterns (EAM patterns) form a technique to bring together practicedriven development and academic research. In the form of EAM patterns, both practitioners and researchers can identify, document, and exchange best practices for the management of EAs. An EAM pattern thereby describes a general, reusable solution to a common problem in a given organizational context. It identifies driving forces, known usages, and consequences. Such patterns can be specified on different levels of abstraction and detail, e.g. as a method for enterprise modeling, or a reference model for the EA management function. Furthermore, EAM patterns address social, technical, and economic issues in a balanced manner. The PEAM workshop wants to provide a platform on which EAM best practices can be discussed and promulgated among European researchers and practitioners with experience in EA management and nearby topics. This is also reflected in the workshop’s make-up consisting of a half-day “classical” workshop, during which research papers on EAM patterns are discussed, and a one-day pattern workshop. On this day, EAM patterns are subjected to intense discussions, where new ideas are collaboratively developed. With this twofold structure, the PEAM workshop brings together the advantages of classical paper-workshops and of pattern-workshops in the tradition of the pattern language conferences of the Hillside Group, as e.g. the PLoP®.

    A decision-making case for collaborative enterprise architecture engineering
    (INFORMATIK 2015, 2015) Jugel, Dierk; Kehrer, Stefan; Schweda, Christian M.; Zimmermann, Alfred
    In modern times markets are very dynamic. This situation requires agile enterprises to have the ability to react fast on market influences. Thereby an enterprise' IT is especially affected, because new or changed business models have to be realized. However, enterprise architectures (EA) are complex structures consisting of many artifacts and relationships between them. Thus analyzing an EA becomes to a complex task for stakeholders. In addition, many stakeholders are involved in decision-making processes, because Enterprise Architecture Management (EAM) targets providing a holistic view of the enterprise. In this article we use concepts of Adaptive Case Management (ACM) to design a decision-making case consisting of a combination of different analysis techniques to support stakeholders in decision-making. We exemplify the case with a scenario of a fictive enterprise.

    EA management patterns for consolidations after mergers
    (Software Engineering 2009, 2009) Buckl, Sabine; Ernst, Alexander; Kopper, Harald; Marliani, Rolf; Matthes, Florian; Petschownik, Peter; Schweda, Christian M.
    Mergers between enterprises or carved-out parts thereof are a common phenomenon in todays economic environment. They nevertheless form a major challenge for enterprise architects, who have to consolidate, i.e. to harmonize and integrate the business capabilities in the newly formed enterprise, reducing redundancy as far as possible. This article presents a best practice approach to this consolidation endeavor, detailing a methodology to do so together with a supporting viewpoint on the enterprise architecture (EA). An information model, which outlines the information demands for methodology execution, is presented to complement the approach.

    EA management patterns for smart networks
    (Software Engineering 2009, 2009) Lau, Armin; Fischer, Thomas; Wieß, Michael; Buckl, Sabine; Ernst, Alexander; Matthes, Florian; Schweda, Christian M.
    With the growing complexity of products and processes in a globalized market, companies are required to strive for a new quality of partnership. In Smart Networks, networking of partners goes beyond mere organizational networking, but involves also networking on the levels of knowledge and information/communication technology (ICT). The setup of ICT networking in newly formed Smart Networks requires not only information about already existing ICT infrastructure, but also a clear understanding of the organizational interconnections and knowledge interdependencies. This paper presents how the respective knowledge can be identified, visualized, and structured through information models in order to obtain decision support for the introduction of additional ICT support for the collaboration within a Smart Network.

    Generating Visualizations of Enterprise Architectures using Model Transformations
    (Enterprise modelling and information systems architectures – concepts and applications, 2007) Buckl, Sabine; Ernst, Alexander M.; Lankes, Josef; Schweda, Christian M.; Wittenburg, André
    Giving account to the importance of enterprise architecture (EA) modeling, this article sketches common issues in visualization handling that we came across dur- ing an extensive survey of the existing tool support for EA management in 2005. We introduce the research project software cartography, in which we develop an approach for EA modeling including a method for the automatic creation of EA models and vi- sualizations. This approach is based on model transformations, which we use to link the data to be visualized and their graphical representation, thereby circumventing the error prone and time consuming task of manual creation of the visual models. A brief overview of a prototypic implementation of this approach complements the theoretic findings and illustrates applicability for visual modeling and documenting the EA.

    Generating Visualizations of Enterprise Architectures using Model Transformations
    (Enterprise Modelling and Information Systems Architectures - An International Journal: Vol. 2, Nr. 2, 2007) Buckl, Sabine; Ernst, Alexander M.; Lankes, Josef; Matthes, Florian; Schweda, Christian M.; Wittenburg, André
    Giving account to the importance of enterprise architecture (EA) modeling, we identify issues in visualization handling that we came across during an extensive survey of existing tools for EA management. We then point to the fundamental principles of software cartography, an approach for EA modeling, including a method for the automatic creation of visualizations based on EA models. This approach is based on model transformations, which link the data to be visualized and their graphical representation, thereby circumventing the error-prone and time-consuming task of manual creation of the visual models. A brief overview of a prototypic implementation of this approach illustrates the practical applicability for visual modeling and documenting EA.

    Interrelating concerns in EA documentation – Towards a conceptual framework of relationships
    (Software Engineering 2010 – Workshopband (inkl. Doktorandensymposium), 2010) Buckl, Sabine; Matthes, Florian; Schweda, Christian M.
    Over the last years a multitude of approaches and frameworks making prescriptions on how to document an enterprise architecture (EA) have been developed. These approaches target different purposes and correspondingly different concerns (areas of interest) in the architecture. In this way, a company seeking to develop or evolve an organization-specific EA documentation technique based on different approaches most likely runs into difficulties to understand the interdependencies between the different frameworks. In this research-in-progress paper, we revisit well-known documentation approaches to devise different types of concern relationships that may be helpful during development and evolution of an organization-specific EA documentation technique.

    Leichtgewichtiges, unternehmensspezifisches IT-Management
    (HMD Praxis der Wirtschaftsinformatik: Vol. 51, No. 5, 2014) Schweda, Christian M.; Schmidt, Werner
    Für die unternehmensspezifische Ausgestaltung des IT-Managements zur Unterstützung des Business-IT-Alignment gibt es eine Vielzahl von Ansätzen und Frameworks. Sie auf die konkrete Situation einer bestimmten Organisation zuzuschneiden und anzuwenden, stellt jedoch insbesondere für KMU eine Herausforderung dar. Der vorgestellte Lösungsansatz sieht vor, nicht nur harte Einflussfaktoren wie Stakeholder und strategische Ziele zu berücksichtigen, sondern geht stärker auch auf weiche Faktoren ein. Dabei werden im Speziellen der Stellenwert und Reifegrad der IT sowie der Reifegrad weiterer Managementsysteme der Organisation wie der strategischen Unternehmensplanung betrachtet. Mit Hilfe von Pattern werden praxiserprobte Lösungen und Vorgehensweisen für bestimmte Problemstellungen des IT-Managements in einem definierten Kontext aufgezeigt. Auf diese Weise können ausgehend von den konkreten Bedürfnissen eines Unternehmens die benötigten Bausteine für das IT-Management identifiziert werden. Anstatt „top down“ ein umfassendes Framework wie TOGAF aufwändig auf die individuellen Belange zurechtzuschneiden, entwickelt man mit der vorgeschlagenen Vorgehensweise das IT-Management eher pragmatisch und „bottom up“, was im Ergebnis zu einem vergleichsweise leichtgewichtigen Konzept führt.

    A method for constructing enterprise-wide access views on business objects
    (INFORMATIK 2010. Service Science – Neue Perspektiven für die Informatik. Band 2, 2010) Buckl, Sabine; Matthes, Florian; Roth, Sascha; Schulz, Christopher; Schweda, Christian M.
    Modern application landscapes consist of a multitude of inter-connected business applications exchanging data in manifold ways. These business applications are used by employees who take on several organizational roles. However, when broadening the scope to an enterprise-wide perspective, lack of clarity and uncertainty prevail regarding the questions which roles have access on which business applications as well as the business objects managed by them. In contrast to alternative approaches, e.g. single sign on, this paper focuses on the enterprise-wide availability of business objects. Motivated by a case study from the car manufacturing industry, this article describes a method to analyze and justify an enterprise-wide access matrix. Respective viewpoints are presented facilitating a business object access management on enterprise level. The method and concepts are further substantiated by means of the case study.

    Patterns of evolution in enterprise architecture information models
    (INFORMATIK 2013 – Informatik angepasst an Mensch, Organisation und Umwelt, 2013) Buckl, Sabine; Schweda, Christian M.
    Enterprise architecture (EA) models are key artifacts for managing the development of the enterprise and in particular its IT landscape, i.e. are central to EA management. The EA models are used to document the current state of the enterprise according to the information demands of EA stakeholders. These demands are reflected in the architecture models' corresponding meta-models, the EA information models. With rising maturity of EA management the group of stakeholders as well as the stakeholders' information demands change. Further, EA management is embedded into a changing environment, where recent regulatory constraints on the one hand and novel technological paradigms keep changing the perspective on the enterprise. Consequently, the EA information models are adapted to accommodate the changed requirements. In this paper, we revisit existing approaches in the area of EA information modeling and discuss the identified lack of support regarding information model evolution. To close the experienced gap, we discuss recurring patterns of adaptation that we observed in the field of EA modeling.
