Event An Event is represented with a circle and denotes something that happens(rather than Activities which are something that is done Icons within the circle denote the type of event(e. g envelope for message, clock for time) Events are also classified as Catching (as in, they might catch an incoming message to Start the process)or Throwing(as in, they might throw a message at the End of the process) Introduction to BPMN, BPEL, and XPDL 2/7202
Event An Event is represented with a circle and denotes something that happens (rather than Activities which are something that is done). Icons within the circle denote the type of event (e.g. envelope for message, clock for time). Events are also classified as Catching (as in, they might catch an incoming message to Start the process) or Throwing (as in, they might throw a message at the End of the process). 11 Introduction to BPMN, BPEL, and XPDL 2/7/2021
Event Start event. Acts as a trigger for the process; indicated by a single narrow border; and can only be Catch, so is shown with an open (outline)icon End event. Represents the result of a process; indicated by a single thick or bold border; and can only Throw, so is shown with a solid Icon Introduction to BPMN, BPEL, and XPDL 2/7202

Event )Intermediate event. Represents something that happens between the start and end events is indicated by a tramline border and can Throw or Catch(using solid or open icons as appropriate) for example, a task could flow to an event that throws a message across to another pool and a subsequent event waits to catch the response before continuing Introduction to BPMN, BPEL, and XPDL 2/7202
