Service oriented architectures have been introduced for various reasons over the previous couple of years. Analogous to the introduction of EAI (enterprise application integration) technologies before re-use and cost cutting potentials have been among the most prominent reasons. But considering the increasing complexity of an application landscape following the introduction of a service oriented architecture, the re-use and cost cutting arguments will lead to disappointment. But service oriented architectures offer a great potential to increase corporate agility. To contribute to this goal it is necessary to manage the enterprise architecture in a sustainable way. This paper discusses the problems of re-use and cost cutting expectations in service oriented architectures and contrasts them with the potentials related to corporate agility. Structures to realize these potentials are discussed with reference to selected case studies.
