Thanks to alf507h and will964 for those very illuminating posts. If you are willing to share I would be very interested in any training material that you produce. I currently teach the TEM theory then follow up with a practical exercise consisting of a real Heli tasking form, other background information and a weather forecast. The group then has to identify the threats and errors and suggest practical strategies to minimise the threats and CRM skills to cope with the errors. This is followed by a case study in which the group has to look at an incident using the TEM framework. The biggest practical application is that it has made us look more closely at our "routine" briefs and really think ahead in a more structured way.
