A formal business process model serves as a common understanding of how business tasks are carried out to achieve end goals. The business process life cycle is managed using Business Process Management tools and methodologies. Business Activity Monitoring provides (near) real-time visibility into process execution notifying relevant personnel of process exceptions. Business process modelling captures business and execution semantics, but lacks any foundation for process analysis. This chapter will outline a model for process performance management for use in the monitoring phase of the process life cycle and how this model is leveraged within the iWISE architecture. iWISE provides a single view of business processes spanning disparate systems and departments.
