Big Visible posted a great photo / poster a few weeks ago with their article Velocity Is Like A Helium Balloon.

Jason Jennings' book Less is More: The main idea: focus. Focus on one thing - one thing for the long term, not one thing this quarter. And that one thing is the big idea of the organization - why is the organization on the planet? That big idea sets the direction and the yardstick by which everything is measured.
