Project management tools are used to manage projects from time as well as from resource leveling perspectives. Workflow management systems guide users through processes by driving the processes based on formal process definitions also called workflow types. This paper describes integrated process management system that will integrate project management, business process modeling, simulation and workflow technologies in order to support scheduled workflow execution. The target will be achieved by utilizing a tool for modeling work processes which can semi automatically generate workflow processes based on scheduling tool and then exported it to workflow engine via web services using XML process definition language (XPDL). Addition of simulation capability allows testing workflows before deployment.
