Inter-organizational systems have significantly
been affected by Service-oriented Architectures (SOA) andWeb
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.
