A workflow system that automates the definition and execution of a procedure that can be carried out according to defined rules among agents. Agents may be individual users, work groups, organizations, or automatic systems. Automation is used to guarantee that all the individual activities are taken in the defined sequence, form, and time. The system separates the three basic elements necessary to perform a procedure-a co-ordination service, an organization service, and a transport service. The coordination service ensures proper sequence of the activities of the procedure. The organization services identifies a particular agent to perform a task within a procedure. The agent selection can be made when the procedure is defined, or it can be deferred until an instance using the procedure is performed. The transport service is used to move information between agents and an information service, which holds instance data, while processing an instance.
