Abstract : Due to business process automation development, process interconnection becomes an important matter. Actually, process interconnection mechanisms are indispensable to co-ordinate business processes within and beyond organisation boundaries, to strength awareness inside virtual enterprises, to facilitate multinational e-transactions, etc. Therefore, thinking and proposing mechanisms to insure interconnection between organisational business processes is becoming a hot topic of research. Actually, existing work co-ordination systems (workflows, shared agenda, co-operative authoring tools, revision and configuration control systems, etc.) have been mainly developed to suit the intern needs of enterprises. Thus most of these systems are not adapted to inter-enterprise co-operation. As we are interested in workflow process co-operation, we aim, through this paper, to provide a model supporting dynamic cross organisational process interconnection. This paper introduces our process model, then our process service model, and finally our process service interconnection model.
