Peter Drucker

"Because its purpose is to create a customer, the business enterprise has two -- and only these two --  basic functions: marketing and innovation.  Marketing and innovation produce results; all the rest are "costs."
-- Peter Drucker, Ph.D., from People and Performance

Another giant has left us but what a legacy he provided.

My favorite Drucker book is Adventures of a  Bystander which gives a glimpse of the development of a man who was far from a "bystander."  I was especially struck by his description of his elementary school education and the learning contracts he wrote.
