I cringe when I read this type of article. Affirmative action doesn't work well in most environments because the diverging views can cripple an organizations ability to act. Just put the best person for the job in the job. By best person I mean the person who is going to fit in, and do the function they are charged with, shaking things up by adding a diversified member just causes trouble, and doesn't make sense in a competitive market. 

If you don't believe me just look at the boards/executive teams of any successful organization. Maybe on the surface there could be some diversification, but at the end of the day the successful boards are made up of individuals who were cut from the same cloth.
