Bennis and O'Toole wrote a paper a few years back arguing that Business Schools had lost their way and were too focussed on quant methods and not enough on real world issues. Their article was widely criticized when it was published in the Harvard Business Review (a sort of B-school magazine).
I blogged about this a month or two back here.
Well, like a bad penny, they are back with an article in Businessweek updating us on the progress that has been made towards their vision.
But nothing has changed really, they were wrong 5 years ago and they are still wrong.
A great rebuttal of their argument is to be found here in an article by DeAngelo, DeAngelo and Zimmerman.
