    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.

    Return on Security Investments – Design Principles of Measurement Systems Based on Capital Budgeting
    (Information systems technology and its applications – 6th international conference – ISTA 2007, 2007) Brocke, Jan vom; Strauch, Gereon; Buddendick, Christian
    IT-security has become a vital factor in electronic commerce nowadays. Thus, investments have to be made in order to safeguard security. However, the benefits of these investments are often hardly visible. In most cases, such investments are made only retroactively, after incidents occur. It is necessary to measure the value before preventing incidents. For this purpose ROSI (Return on Security Investments) has gained enormous attention in research and practice. In this paper, we discuss this measure from a methodological perspective. We argue that existing approaches for calculating ROSI lack a sound methodological basis and that these approaches can be misleading for decision support. In contrast to these approaches, we suggest a new approach for the calculation of ROSI on a capital budgeting basis.
