Rules can call a service and run that service: a service action. They can call a process to invoke (start), suspend, cancel, fail or if it is suspended, to resume itself. Rules can also call a user task within a process, so that a human can make a decision as to the way in which the rule is ultimately applied. This is a unique process action known as a manual decision, sometimes referred to as a task action.

Rule actions are constructed in the Rules Explorer view and then dragged and dropped into decision tables, which are used in rules.
