End Events
Concept
An end event indicates where a process will end. In terms of sequence flow, the end event ends the flow of the process, and thus, will not have any outgoing sequence flow. An end event can have a specific result that will appear as a marker within the center of the end event shape. End event results are error and signal. The end event shares the same basic shape of the start event and intermediate event, a circle, but is drawn with a thick single line.
