The organisational change that comes along with the evolution of enterprise architectures (EA) towards service-oriented architectures (SOA) requires a consolidation of the enterprise's information system. Though, the SOA paradigm is not restricted to application system functionality, but takes also semiautomatic and manual services of an organization into consideration. In order to reach the inter-organizational transparency over the shared resources and processes and to facilitate the reuse of services, a consistent SOA management is recommended. A catalogue system was developed enabling access to both technical and organisational services. Benefits of this approach are illustrated in a pilot study implemented by the MIRO project at the University of Muenster.
