Take monthly reports; these can be bothersome tasks for coordinators who have other work to get done. But the accounting team needs the report in order to settle each month's expenses, so it has to be done…
In this case the Timer Start Event—an event that automatically starts the task on, say, the first day of every month—can come in handy. (Hurray to the inventor of BPMN!)
Some people may dislike the idea of being commanded by a machine. In that case we can arrange a regular route for those who want to start the process manually, at their own timing.
