The Start and End activities allow you to clearly mark where your workflow starts and ends.
Executing a workflow starts with activities without an inbound transition, and stops when there are no longer any tasks in progress. Nevertheless, you can add Start and End activities to clearly mark the starting and ending points of a workflow. This is especially helpful for relatively complex workflows.
It is a best practice to use an End activity instead of leaving the last transition of a workflow on its own to ensure that the workflow properly ends.
Using the External signal tab of an End activity, you can trigger another workflow. Refer to the External signal section.
The following example shows how a complex workflow is executed with a Start activity and several End activities. The Stop all tasks in progress box has been checked for the first End activity. Once the corresponding task is finished, the entire workflow will be stopped: it will have the same effect as if the button had been selected (refer to the Action bar section).
