    On practical implications of trading ACID for CAP in the big data transformation of enterprise applications
    (Digital Enterprise Computing (DEC 2015), 2015) Tönne, Andreas
    Transactional enterprise applications today depend on the ACID property of the underlying database. ACID is a valuable model to reason about concurrency and consistency constraints in the application requirements. The new class of NoSQL databases that is used at the foundation of many big data architectures drops the ACID properties and especially gives up strong consistency for eventual consistency. The common justification for this change is the CAP- theorem, although general scalability concerns are also noted. In this paper we summarize the arguments for dropping ACID in favour of a weaker consistency model for big data architectures. We then show the implications of the weaker consistency for the business customer and his requirements when a transactional Java EE application is transformed to a big data architecture.

    Evolving enterprise architectures for digital transformations
    (Digital Enterprise Computing (DEC 2015), 2015) Zimmermann, Alfred; Schmidt, Rainer; Jugel, Dierk; Möhring, Michael
    The digital transformation of our society changes the way we live, work, learn, communicate, and collaborate. This disruptive change interacts with all information processes and systems that are important business enablers for the digital transformation since years. The Internet of Things, Social Collaboration Systems for Adaptive Case Management, Mobility Systems and Services for Big Data in Cloud Services environments are emerging to support intelligent usercentered and social community systems. They will shape future trends of business innovation and the next wave of information and communication technology. Biological metaphors of living and adaptable ecosystems provide the logical foundation for self-optimizing and resilient run-time environments for intelligent business services and related distributed information systems with service-oriented enterprise architectures. The present research investigates mechanisms for flexible adaptation and evolution of Digital Enterprise Architectures in the context of integrated synergistic disciplines like distributed service-oriented Architectures and Information Systems, EAM - Enterprise Architecture and Management, Metamodeling, Semantic Technologies, Web Services, Cloud Computing and Big Data technology. Our aim is to support flexibility and agile transformations for both business domains and related enterprise systems through adaptation and evolution of digital enterprise architectures. The present research paper investigates digital transformations of business and IT and integrates fundamental mappings between adaptable digital enterprise architectures and service-oriented information systems.

    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.

    Enterprise architecture management for the Internet of things
    (Digital Enterprise Computing (DEC 2015), 2015) Zimmermann, Alfred; Schmidt, Rainer; Sandkuhl, Kurt; Jugel, Dierk; Möhring, Michael; Wißotzki, Matthias
    The Internet of Things (IoT) fundamentally influences today's digital strategies with disruptive business operating models and fast changing markets. New business information systems are integrating emerging Internet of Things infrastructures and components. With the huge diversity of Internet of Things technologies and products organizations have to leverage and extend previous enterprise architecture efforts to enable business value by integrating the Internet of Things into their evolving Enterprise Architecture Management environments. Both architecture engineering and management of current enterprise architectures is complex and has to integrate beside the Internet of Things synergistic disciplines like EAM - Enterprise Architecture and Management with disciplines like: services \& cloud computing, semantic-based decision support through ontologies and knowledge-based systems, big data management, as well as mobility and collaboration networks. To provide adequate decision support for complex business/IT environments, it is necessary to identify affected changes of Internet of Things environments and their related fast adapting architecture. We have to make transparent the impact of these changes over the integral landscape of affected EAM-capabilities, like directly and transitively impacted IoT- objects, business categories, processes, applications, services, platforms and infrastructures. The paper describes a new metamodel-based approach for integrating partial Internet of Things objects, which are semi-automatically federated into a holistic Enterprise Architecture Management environment.

    Energiegenossenschaften - Geschäftsmodelle und Wertschöpfungsnetzwerke
    (Digital Enterprise Computing (DEC 2015), 2015) Küller, Philipp; Hertweck, Dieter; Krcmar, Helmut
    Die Energiewende bietet reichlich Fragen für verschiedenste Wissenschaftsdisziplinen einschließlich der Informatik und Wirtschaftsinformatik (WI). Bedauerlicherweise wurde bisher der Bereich der regionalen Energiegenossenschaften und kleinerer Energieversorgungsunternehmen weitgehend von der WI-Forschung vernachlässigt. Der vorliegende Beitrag stellt die aktuelle Situation dieser Organisationen dar und konzentriert sich auf die bestehende Wissenslücke von Ge- schäftsmodellen (GM) für Energiegenossenschaften (EG) als Zusammenschluss aus Privatpersonen oder kleinen Unternehmen, welche primär regionale, erneuerbare Energie produzieren. Die Modellund Theorieentwicklung basiert auf der klassischen Literaturrecherche, Fallstudien in der Energiewirtschaft (EW), sowie grafischer Modellierung. Als Ergebnis wird das Referenzgeschäftsmodell einer EG als morphologischer Business Model Canvas vorgestellt. Dieses singuläre GM wird um die Darstellung des Wertschöpfungsnetzwerks, welches die strukturelle Einbindung der Akteure in das digitale Ökosystem der EG berücksichtigt, erweitert. Das aus der Forschung resultierende Referenzmodell dient der kritischen Überprüfung empirisch vorfindbarer GM und zur weiteren Entwicklung von Unternehmensarchitekturen digitaler Unternehmensverbünde.

    I*Gov a feeling - ein studienportal für das interaktive heute
    (Digital Enterprise Computing (DEC 2015), 2015) Breu, Manuel; Berndl, Klaus; Heimann, Thomas
    In Deutschland ist der Weg vom Studieninteressenten zum Studenten geprägt von redundanten Datenerfassungen, vielfältigen Anlaufstationen und komplexen Prozessen. Dieses Beispiel ist symptomatisch für viele weitere digitale Leistungsangebote der öffentlichen Hand. Eine niedrige Akzeptanzrate des eGovernments in der Bevölkerung ist damit kaum verwunderlich. Das Rahmenwerk i*Gov liefert Konstruktionsprinzipien um digitale Leistungsangebote so zu gestalten, wie sie der Bürger erwartet. Dieses Positionspapier skizziert ein interaktives, nutzerorientiertes Studienportal, das sich an diesen Konstruktionsprinzipien orientiert.

    Customer services in the digital transformation: social media versus hotline channel performance
    (Digital Enterprise Computing (DEC 2015), 2015) Rossmann, Alexander; Stei, Gerald
    Due to the digital transformation online service strategies have gained prominence in practice as well as in the theory of service management. This study examines the efficacy of different types of service channels in customer complaint handling. The theoretical framework, developed using complaint handling and social media literature, is tested against data collected from two different channels (hotline and social media) of a German telecommunication service provider. We contribute to the understanding of firm's multichannel distribution strategy in two ways: a) by conceptualizing and evaluating complaint handling quality across traditional and social media channels, and b) by testing the impact of complaint handling quality on key performance outcomes like customer loyalty, positive word-of-mouth, and cross-purchase intentions.

    Experiencing adaptive case management capabilities with cognoscenti
    (Digital Enterprise Computing (DEC 2015), 2015) Collenbusch, Danielle; Sauter, Anja; Tastekil, Ipek; Uslu, Denise
    In a world with rapidly changing customer requirements and the increased role of technology, companies need more flexible systems to adapt their processes and react dynamically to changes. Adaptive Case Management (ACM) comes into consideration by providing a concept to adapt to changing business conditions. Within our research project we did a first foundational evaluation of the potential of ACM in supporting unpredictable sales processes. Based on a set of criteria we tested the concept of ACM with the open source tool Cognoscenti. The evaluation gave us the possibility to experience the concept of ACM. Hence we were able to provide a statement about the potential of ACM within the context of an unpredictable sales process, setting the path to further research and discussion of ACM in the area of sales processes.

    Rollenkonzepte im Enterprise Architecture Management
    (Digital Enterprise Computing (DEC 2015), 2015) Wißotzki, Matthias; Köpp, Christina; Stelzer, Paul
    Um die Flexibilität und somit schnelle Anpassung an Veränderungen zu ermöglichen, motiviert durch innere und/oder äußere Einflüsse, haben sich seit Jahren Methoden und Werkzeuge des Enterprise Architecture Managements (EAM) bewährt. Des Weiteren optimiert es die Abstimmung von Geschäftszielen und dessen Strategie mit anderen Architekturebenen. Dies gelingt nur, wenn die damit verbundenen Aufgaben und benötigten Kompetenzen bekannt sind. Obgleich die Fachliteratur auf die Bedeutung von Rollen nachdrücklich hinweist, wurden diese bislang nur spärlich diskutiert. Diese Arbeit analysiert eine Auswahl an Beiträgen in Hinblick auf darin enthaltene Rollenkonzepte. Ziel der Arbeit ist die Erstellung einer Gruppierung von Rollen im EAM, mitsamt den dazugehörigen Aufgaben und benötigten Kompetenzen.
