Sales 2.0 in business-to-business (B2B) networks: conceptualization and impact of social media in B2B sales relationship
(Gesellschaft für Informatik e.V., 2015) Rossmann, Alexander; Stei, Gerald; Zimmermann, Alfred; Rossmann, Alexander
In recent years, the rise of the digital transformation received significant importance in Business-to-Business (B2B) research. Social media applications provide executives with a raft of new options. Consequently, interfaces to social media platforms have also been integrated into B2B salesforce applications, although very little is as yet known about their usage and general impact on B2B sales performance. This paper evaluates 1) the conceptualization of social media usage in a dyadic B2B relationship; 2) the effects of a more differentiated usage construct on customer satisfaction; 3) antecedents of social media usage on multiple levels; and 4) the effectiveness of social media usage for different types of customers. The framework presented here is tested cross-industry against data collected from dyadic buyer-seller relationships in the IT service industry. The results elucidate the preconditions and the impact of social media usage strategies in B2B sales relations.
Feasibility of Bluetooth ibeacons for indoor localization
(Gesellschaft für Informatik e.V., 2015) Estel, Marcel; Fischer, Laura; Zimmermann, Alfred; Rossmann, Alexander
Location-based Services in buildings represent a great advantage for people to search places, products or people. In our paper we examine the feasibility of Bluetooth iBeacons for indoor localization. In the first part we define and evaluate the iBeacon technology through different experiments. In the second part our solution application is described. Our system is able to estimate the position of the user's smartphone based on RSSI measurements. Therefore we used the built-in smartphone sensor and a building map with required sender information. Trilateration is used as positioning technique in contrast to fingerprinting to minimize beforehand effort. Results are promising but cannot reach the same accuracy level as sensor-fusion or fingerprinting approaches.
Appflation - A phenomenon to be considered for future digital services
(Gesellschaft für Informatik e.V., 2015) Benzerga, Sheherazade; Pretz, Michael; Riegg, Andreas; Bounfur, Ahmed; Reimann, Wilfried; Zimmermann, Alfred; Rossmann, Alexander
In recent years, the society has experienced a remarkable change that induced shifts in behavior of people and companies. This effect is reinforced by the evolution of current and the emergence of new technologies such as Smartphones. In this paper it is aimed to contribute to the establishment of a research area for both academic and industrial researchers on what will be described in the following as appflation. First a brief evaluation of the effects of mobile devices and application services on the ongoing digital transformation and the customer/company relationship is provided. Second a definition of appflation is given and the origin and impact of this phenomenon is analyzed by considering the customer and the company side. This analysis is supported by a survey amongst Smartphone users, generally confirming that amongst a vast number of installed apps only a very small number actually is used. Additionally, this survey was used to briefly analyze the usage behavior of the participants in relation to the so called primary IT trends. Finally, in order to encourage researchers to advance the field future areas of interest are identified and drivers that will affect the appflation phenomenon in the future are outlined.
User Engagement in Corporate Facebook Communities
(Gesellschaft für Informatik e.V., 2015) Rossmann, Alexander; Stei, Gerald; Zimmermann, Alfred; Rossmann, Alexander
The stimulation of user engagement has received significant attention in extant research. However, the theory of antecedents for user engagement with an initial electronic word-of-mouth (eWoM) communication is relatively less developed. In an investigation of 576 unique user postings across independent Facebook (FB) communities for two German firms, we contribute to the extant knowledge on user engagement in two different ways. First, we explicate senders' prior usage experience and the extent of their acquaintance with other community members as the two key drivers of user engagement across a product and a service community. Second, we reveal that these main effects differ according to the type of community. In service communities, experience has a stronger impact on user engagement; whereas, in product communities, acquaintance is more important.
Experiencing adaptive case management capabilities with cognoscenti
(Gesellschaft für Informatik e.V., 2015) Collenbusch, Danielle; Sauter, Anja; Tastekil, Ipek; Uslu, Denise; Zimmermann, Alfred; Rossmann, Alexander
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.
Herausforderungen der Projektfertigung - eine Fallstudie zur Informationsbedarfsanalyse
(Gesellschaft für Informatik e.V., 2015) Brümmel, Steffen; Schößler, Martin; Lantow, Birger; Zimmermann, Alfred; Rossmann, Alexander
Insbesondere bei Standardlösungen für ERP-Systeme gestaltet sich die Abbildung der fachlichen bzw. technologischen Zusammenhänge der Projektfertigung im ERP-System schwierig. Mit wechselnden Anforderungen in einer Vielzahl von Projekten stoßen die Systeme an die Grenzen ihrer Flexibilität. Ein Großteil der wesentlichen Informationen zu Fertigungsprojekten liegt außerhalb des ERP-Systems. Mit dem Fernziel einer Assistenzfunktion zur Planungsunterstützung in der Projektfertigung, stellt diese Arbeit exemplarisch die Durchführung einer Analyse zur Informationsbedarfsermittlung nach Lundqvist et al. dar. Ergebnisse sind der Nachweis der grundsätzlichen An- wendbarkeit dieser Methode für dieses Ziel, Erfahrungen bei der Anwendung und Analyseergebnisse sowohl für den konkreten Fall als auch in verallgemeinerter Form.

Providing EA decision support for stakeholders by automated analyses
(Gesellschaft für Informatik e.V., 2015) Jugel, Dierk; Kehrer, Stefan; Schweda, Christian M.; Zimmermann, Alfred; Zimmermann, Alfred; Rossmann, Alexander
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.
Identitäts- und Zugangsmanagement für Kundenportale - Eine Bestandsaufnahme
(Gesellschaft für Informatik e.V., 2015) Weierich, Peter; Weich, David; Abeck, Sebastian; Zimmermann, Alfred; Rossmann, Alexander
Das Identitätsund Zugangsmanagement (engl. Identity and Access Management, IAM) entwickelt sich zu einer Schlüsseltechnologie zur Umsetzung von digitalen Transformationen und der damit einhergehenden Personalisierung. An der Interaktionsschnittstelle zum Kunden ist eine gute Benutzerfreundlichkeit gefragt, damit die Kundenakzeptanz gewährleistet werden kann. Die hier vorgestellte Studie evaluiert die Benutzerfreundlichkeit des IAM von 112 Unternehmensportalen der Branchen Banken, Versicherungen, Automobilindustrie und E-Commerce. Lösungen innerhalb einer Branche sind sich häufig ähnlich, profitieren jedoch nicht von den Erfahrungen anderer Branchen. Jedes der betrachteten Portale hat kleinere und größere Schwachstellen hinsichtlich der Benutzerfreundlichkeit.
Automatisiertes Data Discovery innerhalb eines Provisionierungstools
(Gesellschaft für Informatik e.V., 2015) Bonhorst, Heiko; Kopf, Patrick; Meawad, Fekkry; Zimmermann, Alfred; Rossmann, Alexander
Das Provisioning Tool automaIT wurde prototypisch um die Möglichkeit eines Data Discovery erweitert, mit dem Ziel nicht durch automaIT verwaltete Systeme anbinden und steuern zu können. Daten aus dem Data Discovery werden mittels dem Tool Facter gesammelt und können dynamisch in ausführbare Modelle von automaIT integriert und ausgewertet werden. Dadurch kann der Verlauf weiterer Provisionierungsschritte gesteuert werden, ohne dass es eines manuellen Eingriffs bedarf.
Bottom-up EA Management Governance using Recommender Systems
(Gesellschaft für Informatik e.V., 2015) Govedarski, Konstantin; Hauptman, Claudius; Schweda, Christian; Zimmermann, Alfred; Rossmann, Alexander
Enterprise Architecture (EA) Management is an activity that seeks to foster the alignment of business and IT, and pursues various goals further operationalizing this alignment. Key to effective EA Management is a framework that defines the roles, activities, and viewpoints used for EA Management in accordance to the concerns that the stakeholders aim to address. Consensus holds that such frameworks are organization-specific and hence they are designed in governance activities for EA Management. As of today, top-down approaches for governance are used to derive organization-specific frameworks. These usually lack systematic mechanisms for improving the framework based on the feedback of the responsible stakeholders. We outline a bottom-up approach for EA Management governance that systematically observes the behavior of the actors to learn user concerns and recommend appropriate viewpoints. With this approach, we complement traditional top-down governance activities.
Enterprise architecture management for the Internet of things
(Gesellschaft für Informatik e.V., 2015) Zimmermann, Alfred; Schmidt, Rainer; Sandkuhl, Kurt; Jugel, Dierk; Möhring, Michael; Wißotzki, Matthias; Zimmermann, Alfred; Rossmann, Alexander
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.
Customer services in the digital transformation: social media versus hotline channel performance
(Gesellschaft für Informatik e.V., 2015) Rossmann, Alexander; Stei, Gerald; Zimmermann, Alfred; Rossmann, Alexander
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.
I*Gov a feeling - ein studienportal für das interaktive heute
(Gesellschaft für Informatik e.V., 2015) Breu, Manuel; Berndl, Klaus; Heimann, Thomas; Zimmermann, Alfred; Rossmann, Alexander
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.
Energiegenossenschaften - Geschäftsmodelle und Wertschöpfungsnetzwerke
(Gesellschaft für Informatik e.V., 2015) Küller, Philipp; Hertweck, Dieter; Krcmar, Helmut; Zimmermann, Alfred; Rossmann, Alexander
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.
Goal-oriented Decision Support in Collaborative Enterprise Architecture
(Gesellschaft für Informatik e.V., 2015) Hamm, Thomas; Kehrer, Stefan; Zimmermann, Alfred; Rossmann, Alexander
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.

Mittels disruptiver Innovationsmethoden haben Google, Apple, Facebook und Co. bereits Branchen grundlegend verändert und Marktführer wie Nokia oder Otto innerhalb weniger Jahren abgelöst. Die folgende Arbeit befasst sich mit diesen Methoden und der Fragestellung, wie sie in den automotiven Produktentstehungsprozess integriert werden können, um nachhaltig erfolgreiche Geschäftsmodelle am Markt platzieren zu können.
On practical implications of trading ACID for CAP in the big data transformation of enterprise applications
(Gesellschaft für Informatik e.V., 2015) Tönne, Andreas; Zimmermann, Alfred; Rossmann, Alexander
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
(Gesellschaft für Informatik e.V., 2015) Zimmermann, Alfred; Schmidt, Rainer; Jugel, Dierk; Möhring, Michael; Zimmermann, Alfred; Rossmann, Alexander
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.
