    ITIL als Common-Practice-Referenzmodell für das IT-Service-Management — Formale Beurteilung und Implikationen für die Praxis
    (Wirtschaftsinformatik: Vol. 46, No. 5, 2004) Hochstein, Axel; Zarnekow, Rüdiger; Brenner, Walter
    In the course of increasing customer orientation in the IT sector, IT service management becomes more important. Especially the de facto standard ITIL receives attention of IT management at present. Deficits of the ITIL reference model are often ignored, benefits are only assumed and a lot of misunderstandings exist. Uncertainties, unfulfilled expectations and problems during the accomplishment of ITIL projects are the result. In this context the paper deals with a critical analysis of the ITIL reference model. It fulfils a formal evaluation of the model on the basis of established criteria. On the basis of this evaluation implications for IT management are derived. Findings are derived from four case studies as well as an in-depth analysis of the ITIL documentation itself.

    Referenzmodellbasierte Einführung von Führungsinformationssystemen Grundlagen, Anforderungen, Methode
    (Wirtschaftsinformatik: Vol. 46, No. 5, 2004) Goeken, Matthias
    Due to the fact that still many Executive Information System (EIS) Projects fail, it seems to be worthwhile to improve the likelihood that these efforts finish successfully. Reference models can foster the development of EIS because they provide reference solutions for a specific Domain. This paper presents a method for the Development of EIS based on reference models. The method includes a life cycle model which supports the adaptation of reference models and an extension of multidimensional data models allowing the management of variants and adaptation points. Furthermore, it provides construction patterns for a specific domain. The development of an EIS at Universities is used as a motivating example.

    Internetbasierte Referenzmodellierung — State-of-the-Art und Entwicklungsperspektiven
    (Wirtschaftsinformatik: Vol. 46, No. 5, 2004) Brocke, Jan
    Die Referenzmodellierung lebt von der interpersonellen Abstimmung. Das Intenet bietet hierzu vielversprechende technische Möglichkeiten. Mit diesem Beitrag wird untersucht, in welchem Ausmaß das Internet im gegenwärtigen State-of-the-Art der Referenzmodellierung genutzt wird. Auf dieser Grundlage können Perspektiven zur weiteren Erschließung des Potenzials einer internetbasierten Referenzmodellierung aufgezeigt werden.

    E-MEMO: Referenzmodelle zur ökonomischen Realisierung leistungsfähiger Infrastrukturen für Electronic Commerce
    (Wirtschaftsinformatik: Vol. 46, No. 5, 2004) Frank, Ulrich
    For many companies, the development of a competitive E-Commerce strategy and even more so its implementation is a huge challenge. This paper presents a method that is aimed at reducing substantially cost and risk of such an endeavour. The method has been adapted from an existing method for multi-perspective enterprise modelling. It supports strategy analysis and design as well as the corresponding organisational design. It also fosters the configuration of supporting information systems. Besides specialized process models, the method offers reference models for strategy design and a library of business process models. The process models can be transformed automatically into workflow schemata.

    Organisationsformen in der Referenzmodellierung — Forschungsbedarf und Gestaltungsempfehlungen auf Basis der Transaktionskostentheorie
    (Wirtschaftsinformatik: Vol. 46, No. 5, 2004) Brocke, Jan; Buddendick, Christian
    Reference models are built in order to increase the efficiency of information system development. By means of exchanging solutions for typical design problems the reuse of information models can be enhanced. Although there is an affluent number of works on reference modeling, existing reference models are rarely used in practice. One reason can be seen in the existence of various different institutional arrangements for the exchange of models that have not yet been at the focus of research. With this article, we recommend to enlarge the field of research on reference modeling by taking organisation theory into account. By considering Transaction Cost Economics alternative organisational patterns can be identified and examined by means of their „fit“ to a specific environmental situation. The implementation of hybrid organisations seems to be a promising approach for promoting the diffusion of reference models in practice. Therefore we explain how to apply networks as hybrid organisations in reference modelling.
