Abstract

Service orientation has been a major
buzz-word in recent years. While the
buzz is on a decline, organizations are
slowly, but steadily moving towards
service oriented designs. However, service
orientation turns out to be as much
of a managerial challenge as of a technical
one. The most important complexity
drivers in the service oriented
design of information systems seem
to be (a) inconsistent design goals of
stakeholders and (b) the pursuit of exhaustive
service orientation coverage.
This research focuses on the following
two questions: (1) What are the characteristics
of successful implementations
of service oriented information
systems, and (2) what are the critical
success factors influencing, driving
and/or, determining these characteristics?
Data of an empirical analysis is
used to test a set of cause-effect relationship
hypotheses based on nine latent
variables. In the core of this model
we differentiate the variables “overall
service orientation infrastructure success”
and “service orientation project
success”. The hypothesized interrelationships
between the nine variables
lead to a causal model which is proven
to hold.
