CRM is also being adopted by emergency responders (EMTs) and so on. I've started to use it whenever possible in important or high stress situations dealing with people. Stuff like repeating peoples questions to them so they hear your interpretation of what they said. Always responding to questions, even if the answer is "I don't know yet" or "I'm still working on it".

It's like taking a protocol like TCPIP and mapping it onto human interactions to provide a lot more robustness and remove many sources of mistakes.

There are more elements to CRM, but finding good breakdowns of examples seems to be tied up in paid or industry training and harder to dig up as a layman.
