Routes are the links between Actions and Tasks which build relations within the process diagram.
You can draw multiple routes, from a single action to the multiple tasks to split workflow in more than a one branch. If no route is found, or all of the routes are invalid, workflow is automatically terminated.
For a route you can configure the following properties from the context menu:

Validation Rule
