Term Definition: Intermediate Event
Main Description

An Intermediate Event is an event that occurs after a Process has been started. It will affect the flow of the process, but will not start or (directly) end the process. An Intermediate Event will show where messages or delays are expected within the Process, disrupt the Normal Flow through exception handling, or show the extra flow required for compensating a transaction. The Intermediate Event shares the same basic shape of the Start Even and End Event, a circle, but is drawn with a thin double line.
