Service-Oriented Architecture for Supporting Distributed User Interaction Design

Professionals working in organizations conducting user interaction design are more and more involved in a collaborative setup where competences and resources are distributed in time and space. In order to support this shift of practice, a service-oriented architecture is defined and developed according to principles of model management. In this paradigm, user interaction design is decomposed into activities, which could be supported by model management operations. These operations are in turn converted into services, developed according to the architecture. A distributed user interaction design life cycle consequently involves the following steps: a method engineer defines the activities to be conducted for a user interaction project, the method definition is imported in the architecture to enact the method by assigning responsibilities to team members, and these members then perform their responsibilities through the services corresponding to the operations
