I was listening again to Andy Stanley's presentation from The Leadership Summit 2003, and was struck by this statement:
Vision doesn't stick when you're successful because when you are successful, you have options and if you have too many options you get unfocussed...You wake up one day in a large organization and the largeness has made it complex, and complex organizations are stupid organizations. The smartest [my organization] has ever been - unbelievably efficient - was when there was just six of us.
But as you are successful, you become complex, and complexity is the enemy of efficiency and complexity is the enemy of vision. It could be that you're in a successful organization, but the vision hasn't stuck. Everybody's busy, but you've lost the connection.
