Workflow management systems enable the exact and timely analysis of automated business processes through the analysis of the logged audit trail data. Within the research project CONGO1 we develop a process analysis tool (PISA) that can be employed to analyze the audit trail data of different workflow management systems in conjunction with target data from business process modeling tools. A working prototype has been completed that integrates data of the ARIS Toolset and IBM MQSeries Workflow. The analysis focuses on three different perspectives – processes and functions, involved resources, and process objects. We outline the economic aspects of workflow-based process monitoring and controlling and the current state of the art in monitoring facilities provided by current workflow management systems and existing standards. After a discussion of the three evaluation perspectives, sample evaluation methods for each perspective are discussed. The concept and architecture of PISA are des...
