A system and method for performing scalable distribution of process flow activities in a distributed workflow management system is described. The distributed workflow management system operates over the computer network which includes a plurality of interconnected computers. Each computer includes a processor, memory and input/output facilities. A plurality of resources are each operatively coupled to at least one of the computers and execute at least one of the activities in the process flow. A process flow engine, including a database in which is stored data used in effecting each of the process flow activities, coordinates and schedules execution of the process flow activities on the resources. Bidirectional proxy components are operatively interposed between the process flow engine and the resources. The bidirectional proxy components include logic for handling application data for the resources, logic for handling worklists for access by the resources and logic for managing transport of messages between the process flow engine and each of the resources.
