Typical examples are engineering design activities, office procedures, and banking systems.
All these human-centered systems are characterized by the interaction among people, and between people and computerized tools. To support these systems, process-centered environments and workflow management systems have been recently developed. They can be collectively identified with the term process technology . The model specifies the kind of support that has to be provided to human agents. An essential property that process technology mut exhibit is the ability of tolerating, controlling, and supporting deviations and inconsistencies of the real-world behaviors with respect to the proocess model.
