My question is can you seriously tech CRM? You can put individuals in a classroom, you can force into them all the theory and they will learn all the right answers. But when it comes into applying them will they do it willingly if they don't have to?
This is a very good question not really addressed by most of the answers above.
Starting at the beginning you cannot teach anybody anything to anyone if they do not wish to learn, ask any secondary school teacher.
We had an instructor (large UK airline) who wasnt a pilot and had become a bit of a laughing stock, no one respected his opinion or his views, the course was dead in the water before it started.
So for starters you need properly motivated students and properly qualified instructors who can teach with authority and are respected. I cannot see how any instructor without years of airline flying experience can be a CRM instructor.
I also believe a lot more CRM checking should take place during line checks.
