Workflow management systems enjoy increasing popularity due to their ability to coordinate and streamline complex organizational processes within organizations of all sizes. Control of these processes allows an organization to reengineer and improve or adapt them. Interest in workflow management systems was demonstrated in the early 1990s by an increased number of commercial products in an estimated $2 billion market. This book addresses recent advances in workflow management systems. Based on a NATO workshop held in 1997, it is an integrated collection of papers by leading international researchers. Topics emphasized include interoperability, Internet technologies to improve system capabilities, scalable and dynamic cooperation technologies, and workflow system prototypes.
