The greatest challenge to organizations is the balance between continuity and change. You need both. At different times, the balance is slightly more over here, or slightly more over there, but you need both. And balance is basically the greatest task in leadership. Organizations have to have continuity, and yet if there is not enough new challenge, not enough change, they become empty bureaucracies, awfully fast.
