Towards Requirements for a Reference Model for Process Orchestration in e-Government

A big challenge for governments all over the world is to improve the service provisioning to their clients, citizens and businesses. One way of improving service-provisioning is by means of a a one-stopshop that integrates services that are performed by different semi autonomous agencies. This requires the coordination of service-delivery processes that run across different agencies. This is also called process orchestration. As little is known about process orchestrators, governmental decision-makers need support in designing them. This paper investigates the applicability of existing reference models from domains that are closely related to process orchestration, the Workflow Reference Model and the extended SOA reference model, to governmental decision-makers for implementing process orchestration in e-government, and identifies several main requirements for a reference mode for process orchestration, based on a case study performed at a business counter.
