Rules can call a service and run that service: a service action. They can call a process and tell it to invoke (start) itself, or, if it is already running, to suspend itself/cancel itself/fail itself, OR, if it is suspended, to resume itself. Rules can also call a user task within a process in order 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 can then be dragged from there into decision tables, which can then be used in rules.
