Nice post Brian. I would add a factor to the discussion, though, and that is the idea that transformative change is often associated with great "trauma" (which is often why people vote for incremental). Gary Hamel tackles that issue in his recent book, and I blogged about it in June. There are ways to achieve what he calls "trauma free renewal" in organizations, and i think that is required more than we might admit. That's not to say incremental change is bad. I thought your example was excellent. But I think if we did change differently we'd be able to do transformative work when we need to.
Thanks for the comment Jamie. You're absolutely right. I like the reference to change as renewal.
