But with successful large-scale adoption also comes the observation that SOA is not immune to the unforgiving laws of software evolution. As SOA systems grow and evolve to meet continuously changing business needs, the complexity and ensuing cost of maintenance and adaptation rises.

 

To tackle the problem of rising complexity and cost of service-oriented systems, a research project has been initiated that aims to close the gap between the re-engineering solutions that have been developed for traditional information systems and the new re-engineering challenges posed by SOA. Partners in the Re-engineering Service-Oriented Systems (ReSOS) project are Delft University of Technology, KPMG, and SIG.
