> "There's been this belief that if you do an MBA or other forms of management training, then that means you're [automatically] a good manager, but all of our evidence shows that that's absolutely not the case,"

as an mba holder myself, i can only say what i know, but i went in there with the explicit knowledge that im going to be learning the tools of business and management (statistics, accouting/book keeping, finance, marketing, strategy, management control etc) and that to be a real manager you have to be experienced actually managing things (and learn what works and fails, how people are really motivated etc)

i guess if some people go into mba programs expecting to be managers or able to manage people right from the start, they are very likely to be in for a rude awakening

maybe i live in a bubble, but do people actually expect that just getting an mba = compitent manager??
