Other than in airplanes can you think of places where CRM might be important?
Helicopters ;-) Ok, smartaleckness aside, sure CRM can be utilized outside of aviation. The meat and potatoes of the matter is dealing with different personalities to accomplish a common goal effectively and, key word: safely. Does it always have a positive outcome? I don't believe there are absoloutes in anything, but lack of CRM in aviation has certainly led to some pretty tragic accidents such as the L-1011 over the everglades that lawn darted in because the crew was focused on a gear light.
