Upcoming conference

Next week Marco will present our paper “Inter-organizational Systems: From Business Values over Business Processes to Deployment” at the IEEE International Conference on Digital Ecosystems and Technologies in Phitsanulok (Thailand). More Information about this conference can be found here: http://www.ieee-dest.curtin.edu.au/2008/index.php

The abstract of the paper:

Inter-organizational systems have significantly been affected by Service-oriented Architectures (SOA) and Web Services – the state-of-the-art technology to implement SOA. SOA is said to enable quick and inexpensive changes of the IT in order to establish new business partnerships or to reflect changes in existing partnerships. However, current approaches to inter-organizational systems focus too much on existing Web Services standards and, thus, on the technology layer. In such an approach the technology drives the business. In this paper we analyze the shortcomings of this bottom-up approach. As an alternative we suggest a top-down methodology where the business requirements drive the technology. This methodology starts off with the business value perspective, leading to a business process perspective and resulting in an IT execution perspective. We do not invent any new approaches on each of these layers, rather we outline how existing approaches are used and combined into a business requirements driven approach to inter-organizational systems.

Pre-draft REA Profile for Enterprise Architect available

Yellow FolderFor those interested we have uploaded a first version of the UML Profile for REA for Enterprise Architect together with a (still incomplete) test model. We will continue our collaborative work with Prof. McCarthy in order to allow for a seamless integration of REA into the UMM.

REA will become a specialization module of UMM

Bill McCarthy from Michigan State university is currently in Vienna and we are working together on a UMM specialization module for REA (Resources-Events-Agents). The REA Enterprise Information Architecture covers the value chain and supply chain of an enterprise system. A first version of the specialization is scheduled for the UMM Forum meeting taking place in Mexiko City from the 7th – 11th April 2008.

More information on REA can be found on Prof. McCarthy’s website.
