Great post and wonderful video.

Kantor's four-player model http://mitleadership.mit.edu/r-fpmodel.php suggests much the same. Wayyy back in the last century (1999) William Isaacs adapted and wrote about Kantor's model http://www.dialogos.com/resources/files/systhink.pdf There's an iPhone app just out also, the four-player model mini assessment, that I quite like.

I posted about one way of using the model and process http://thoughtstreamblog.ca/defining-team-roles-score-big-with-the-four-player-model/ It's great to see this kind of thinking getting a bit more attention.

Another great resource supporting this is a book called The Opposable Mind by Roger Martin.

I do have a question, but it related more to your last post on complexity so will ask it there.
