    Geschäftsmodelle für dienstebasierte Informationssysteme
    (Wirtschaftsinformatik: Vol. 50, No. 1, 2008) Nüttgens, Markus; Dirik, Iskender
    In diesem Beitrag wird ein Marktmodell entwickelt, welches eine Kategorisierung und Positionierung der Anbieter von Webservices und ihrer Geschäftsmodelle ermöglicht. Die fünf resultierenden Geschäftsmodelle basieren auf drei Differenzierungskriterien: Der Branche der Webservice-Anbieter, dem Nutzen und der strategischen Bedeutung für den Webservice-Anbieter. Als Erlösmodelle für Webservices können direkte und indirekte sowie transaktionsabhängige und transaktionsunabhängige Erlösformen un-terschieden werden. Durch die Einordnung konkreter Fallbeispiele von Webservice-Anbietern in eine Geschäftsmodellmatrix kann der Nutzen des erarbeiteten Instru-mentariums aufgezeigt werden.AbstractIn this article a web service provider model is developed that allows the categorization of suppliers of web services and their underlying business models. The resulting five business models are based on three criteria of differentiation: The branch, the value and the strategic relevance for the supplier of the web services. The revenue models of web services can be direct or indirect and dependent or independent of the underlying transactions. By mapping case studies of existing web service suppliers towards a business model matrix, the benefit of the developed concept can be shown.

    Interpretation des Sourcings der Informationsverarbeitung: Hintergründe und Grenzen ökonomischer Einflussgrößen
    (Wirtschaftsinformatik: Vol. 45, No. 5, 2003) Dibbern, Jens; Heinzl, Armin; Leibbrandt, Silvia
    This article aims to develop a more profound understanding of the heterogeneous behaviour in the field of Information Systems (IS) Outsourcing in German organizations. Based on multiple case studies in the German Manufacturing Industry, it demonstrates that resource deficits serve as an overriding contingency for the outsourcing decision. However, specific knowledge on internal business processes may lead to production cost advantages for the firm and, thus, inhibits the outsourcing of IS functions. Furthermore, cultural variables like distrust and sociability serve as additional contingencies for explaining heterogeneous outsourcing patterns.

    PBroker und Contracker — Web-gestützte Plattformen für das Management von Freelancern und das Vertragsmanagement
    (Wirtschaftsinformatik: Vol. 45, No. 2, 2003) Wägli, Daniel; Knolmayer, Gerhard F.
    The Internet may change existing structures of value chains and outsourcing relationships and lead to disintermediation, reintermediation, and metamediation. In this paper we describe PBroker, a web-based external service which supports the procurement and administration of freelancer services. Based on a description of the freelancer market, the functionalities of the PBroker platform are described. We discuss the business model of and present experiences with the system. One of the tasks supported by the PBroker system is the management of freelancer contracts. This contract management module has recently been enlarged to a system called „ConTracker“ which supports the management of all types of contracts by structured documentation of contractual issues and alert mechanisms for time-dependent events.
