This illustration shows the Travel Request Process, which contains the following:

Two equal horizontal regions called swimlanes.

The top swimlane is labeled Employee and the bottom swimlane is labeled Manager.

Each swimlane contains flow elements (left to right) and sequence flows.

The process starts at the left end of the Employee swimlane with the Submit Travel Request start event.

There is a sequence flow from Submit Travel Request to the Approve Travel Request approve human task in the Manager swimlane.

From the Approve Travel Request the process flows to the right to the Approved? gateway.

There are two sequence flows coming out of the Approved? gateway.

The No sequence flow points to the Redo Travel Request submit human task in the Employee swimlane.

The Yes sequence flow points to the Fulfill Travel Request submit human task in the Manager swimlane.

The Fulfill Travel Request task has a sequence flow that points to the Completed end event which signifies the end of the process.

The Redo Travel Request task has a sequence flow pointing to the Approve Travel Request task.
