Abstract
To fit economical constraints, enterprises are more and more involved in collaborative strategies and require agile organization. To support such agile organizations, an efficient and agile IT system should be set. This can be partially achieved thanks to Service Oriented Architectures (SOA) that are able to implement opened and agile information system. The collaborative model we built on this approach is based first on the services exposed by each potential partner and then on a convenient assembly process used to build a cooperation process, designed as a services composition. This architecture impacts the enterprise own organization, leading to a service oriented enterprise (SOE). After describing the context we present the SOE framework and its components. Then the assembly process is described.
