Modeling business processes for web-based information systems development

We are entering the era off-business. Organizations are becoming more and more global and virtual. Modern ICT (Information and Communication Technology) offers the enabling potentials for realizing these organizations. However, the cui-rent practice of information system development Is not able to meet the new requirements. Not only do developers need a profound insight in the technological potentials; also do the business system architects need an appropriate understanding off-business and of the business processes in the future organizations. This paper presents such an appropriate understanding, in which an organization is modeled completely abstracted from all realization issues. The potentials of this new understanding, called the OER-paradigm, are presented and discussed, and the practical usefulness is demonstrated by applying the DEMO methodology, which is fully based an the OER-paradigm, to the example of a library (OER stands for: Order, Execution, Result).
