Goal Events allow to set a contact Goal for a workflow. The moment a contact enters the workflow the system will be "listening" for the specified Goal Event to occur regardless of the step the contact is in. Once the contact has met the goal conditions, the contact will be pulled into the goal step, regardless of where they are in the workflow

Goal Events will remove the need for any secondary workflows that you've created that removes, continues or ends a workflow for a contact.
