Mainstream justification for Agile?

Dave Murphy at the On Be(come)ing Agile Blog talks here about a Harvard Bussiness Review article by Nitin Nohria and Thomas A Stewart title "Risk, Uncertainty and Doubt" available here I haven't read the article but Dave has an interesting take on how this article supports the justification for an Agile approach. I think it's interesting to see an article like this in such a mainstream publication that is so widly read at the top levels of management. Maybe this is the start of management seeking out Agile practisioners to help manage their risk rather than than the othe way round. Perhaps not. Still an interesting read.
