Sequence Flows
A Sequence Flow is used to show the order that activities are performed in a process flow.
A Sequence Flow is drawn as a line with a filled in arrowhead. It can only be drawn between processes and gateways and events within a pool. You cannot draw a Sequence Flow between symbols that are in different pools. Only Message Flows are allowed between pools or lanes.
