If you wrote a list of what a great leader brings an organisation I'll bet direction and vision would be on there but this should never mean getting to a final destination - that would be fatal. Business models that can't change, teams that don't innovate and cultures that wont develop are going to get stuck exactly there - at a final destination.
We are not talking about change for changes sake here, we are talking about continuous betterment of what we offer, the ways we work and indeed the leaders we are.
