This is a series of several programs narrated by a former professor at the London Business School (a guru himself) Charles Handy.
One of the programs talks about Peter Drucker who gave us the concept of a "knowledge worker" that David Allen refers to in his books and seminars.
Peter Drucker's best book (in my mind) The Effective Executive www.palmdigitalmedia.com/product/detail/6838 talks about a lot of what we here like to talk about on this board.
Anyway, I thought this would be a great series for a beginner in the study of Management and a refresher for the rest of us. (I majored in Management myself and got a Bachelor's in it, so the series was a great way to hear again about the people whom my school books talked about and as well as those whom they neglected to mention much).
