Here here Fernando.
In my forums I always call it Company Resource Management.
One of the original definitions came from John Lauber (NTSB 1982) <one of the original CRM Gurus>:
"CRM is the use of all available resources - Software, Hardware, and Liveware - to accomplish a safe and efficient flight."
(Yes - the term "Liveware" does make me shudder a little.... but I use this quote because it is "from the horse's mouth" so to speak!)
Or, alternatively, you could try:
CRM = Captain's Right Mate!!!
.....works for some people!!
