Gary Hamel

Gary Hamel is the originator (with C K Prahalad) of the concept of core competencies... His academic standing took a dent soon after publication of the hardback version of Leading The Revolution, in which he had written a very positive profile of Enron. Following the strong reception of Leading the Revolution, Hamel began work on Resilience in Business Strategy. http://en.wikipedia.org/wiki/Gary_Hamel
