I don't know Henry Mintzberg. I wish I did.
But I've read a bunch of his work and it resonates with me at a deep level for a host of reasons, but primarily because he sees enterprises as a collection of humans, not cogs of production. And secondly, he calls 'em as he sees 'em. He seems fearless in this regard.
If you've never read any of his work, and you want to get a sense of exactly what I'm talking about, just read this one short article in the Economist. This guy throws with serious heat.
