    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.

    Goal-oriented Decision Support in Collaborative Enterprise Architecture
    (Digital Enterprise Computing (DEC 2015), 2015) Hamm, Thomas; Kehrer, Stefan
    Decision-making in the field of Enterprise Architecture (EA) is a complex task. Many organizations establish a set of complex processes and hierarchical structures to enable strategydriven development of their EA. This leads to slow and inefficient decision-making entailing bad time-to-market and discontented stakeholders. Collaborative EA delineates a lightweight approach to enable EA decisions but often neglects strategic alignment. In this paper, we present an approach to integrate the concept of Collaborative EA and goal-driven decision-making through collaborative modeling of goal-oriented information demands based on ArchiMate's Motivation extension to reach a goal-oriented EA decision support in a collaborative EA environment.

    Providing EA decision support for stakeholders by automated analyses
    (Digital Enterprise Computing (DEC 2015), 2015) Jugel, Dierk; Kehrer, Stefan; Schweda, Christian M.; Zimmermann, Alfred
    Enterprise architecture management (EAM) is a holistic approach to tackle the complex Business and IT architecture. The transformation of an organization's EA towards a strategyoriented system is a continuous task. Many stakeholders have to elaborate on various parts of the EA to reach the best decisions to shape the EA towards an optimized support of the organizations' capabilities. Since the real world is too complex, analyzing techniques are needed to detect optimization potentials and to get all information needed about an issue. In practice visualizations are commonly used to analyze EAs. However these visualizations are mostly static and do not provide analyses. In this article we combine analyzing techniques from literature and interactive visualizations to support stakeholders in EA decision-making.
