AN EVOLUTION PROCESS FOR SERVICE-ORIENTED SYSTEMS

Andrzej Zalewski, Marcin Szlenk, Szymon Kijas

Abstract


Evolution of service-oriented systems is quite a new research area, which becomes
more and more important as engineering challenges move from enabling
service-orientation onto the maintenance and evolution of already developed
service-oriented systems. However, the development of suitable evolution processes
and methodologies is still an open research problem. The evolution process
presented in this paper has been designed to address the evolution of serviceoriented
systems, which are technically built out of a set of service compositions.
The presented process comprises phases and tasks compliant with ISO 20000.
The underlying model of service-oriented system consisting of business processes
and corresponding service composition models has also been presented. A traceability
model and tools supporting change impact analysis have also been
provisioned for. Preliminary industrial validation indicates that the evolution
process should be easy to adapt by the industry.

Keywords
