1. Introduction Workflow management systems [1] support the definition and execution of business processes. The major constructs in drawing processes are activities and control connectors. The activities describe the tasks to be performed, and the control connectors describe the potential sequence in which the activities are to be carried out. Figure 1 shows schematically the structure of such a process graph. Figure 1 Process Model Activities are represented as named circles; the name typically describes the purpose of the activity. Activities come in various flavors to address the different tasks that may need to be performed. They may have different activity implementations to meet these diverse needs. Program activities are performed by an assigned program, process activities are performed by another process, and blocks implement a macro with a built-in do-until loop.
