We are beginning to see distributed dynamic workflow management systems being implemented using CORBA services. However, these systems do not use events as the mechanism for co-ordinating workflows. Instead, workflow components use messages to communicate with each other, thereby resulting in tightly coupled systems. We investigate the use of events as the co-ordinating mechanism for implementing dynamic event-based workflow solutions using existing CORBA services. This paper shows the limitations of the CORBA Event Service for dynamic workflow solutions based on a prototype implementation and proposes a more specialised Workflow Event Channel (WEC) that overcomes these limitations. A CORBA implementation of the WEC design enables event-based workflow execution environments within a CORBA framework
