    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.

    Roadmaps for enterprise architecture evolution
    (Software Engineering 2010 – Workshopband (inkl. Doktorandensymposium), 2010) Ernst, Alexander M.; Schneider, Alexander W.
    Managing the enterprise architecture (EA) is a major challenge of every larger modern enterprise. Aligning business and IT in order to optimize their interaction is the main goal of EA management. The first step of an EA management approach typically is to analyze and document the as-is-situation. Subsequently, the second step has to be the management of the EA evolution in order to achieve the desired target EA. Although IT projects guide this evolution by implementing the transformations from a current to an envisioned architecture, they are considered sparsely by EA approaches. Therefore, this article presents a methodology pattern (M-Pattern) describing a process including all necessary tasks and associated roles, which help to cope with the challenge of EA evolution management.

    Teaching enterprise architecture management with student mini-projects
    (Software Engineering 2010 – Workshopband (inkl. Doktorandensymposium), 2010) Buckl, Sabine; Ernst, Alexander M.; Matthes, Florian; Schweda, Christian M.
    Enterprise architecture (EA) management is one of the major challenges of modern enterprises. It aims at aligning business and IT in order to optimize their interaction. Experts in this context are scarce and only limited proven practice to educate students in EA management is yet available. This paper presents a pattern on how to teach EA management based on experiences and best practices gained in a lecture at the Technische Universität München.
