From Consultant News.com:
"Harvard Business Review has announced that Michael E. Porter and Mark R. Kramer are the first-place winners of the 2006 McKinsey Award for their article Strategy and Society: The Link Between Competitive Advantage and Corporate Social Responsibility. Gary Hamel is the second-place winner for The Why, What, and How of Management Innovation."
I believe that Hamel's approach to innovation is a bit of old-school, monolithic, enterprise focussed. However Porter and Kramer's work sounds very interesting. Have to get my hand on that article.
