Replace the term CRM with the words "Good manners, good airmanship, and commonsense" because that is all it really is.
Sorry, I couldn't disagree more. If that was all it is, then it would be very, very easy. Without wishing to be personal, and therefore very specifically
not accusing HSWL of this since I don't know him/her, this can often be the sort of things said by people whose CRM is severely lacking and who seek to justify their lack of said CRM ability.
CRM is about far more. It is about communication (which includes ENABLING others to speak out without fear and LISTENING). It is about encouraging others to THINK. It is about knowing where your limitations (and those of others) begin and end, therefore considerable self-knowledge. It is about ensuring others are always in the loop (good airmanship is all very well, unless you are doing it all on your own).
I could go on for a long time. But you will be pleased to hear that I won't.
