I think that the requirement is for a PDM (Pilot Decision Making) Course. Similar to CRM.
CRM is not only a Crew Resource Management skill specifically, but a Cockpit Resource Management utilization, in the case of a single pilot.
Whether you are Single or Multi Pilot, you must always make use of all resources available to you in the case of a single pilot, Cockpit and in the case of Multi Pilot, Crew.
Hope that helps.
