I think it depends in the task, and what the interest of the various groups are. If you have 10 engineers but only 2 of them are really passionate about it, and the other 8 would rather be doing something else, but due to incentives based on their minority status, they decided it was worth the extra money, you'd probably do a lot worse than a company which had 10 engineers that were all hired based on merit.
