Susan Mazza... loved this-
"Interdisciplinary efforts only work well when there is a clear and compelling goal the participants share.  This creates the experience of being on one team which is essential to turning us and them into a we."

Can you elaborate a little? How do we set that "clear and compelling goal"?  Is that something the leader does alone?  With a small group of leaders within the organization?   Also, does it have to just one goal, or can it be several?

I want to be the leader that turns "us and them" into "we"!  Thanks for the encouragement!
