Sorry for the delay, I have been so deeply engaged in class (and doing the homework) that it has been hard to come up with a central idea for a post. Then it occurred to me that the topic is excellence, and how it differs from perfection. We been looking at a variety of organizations that focus on excellence through action and iteration. While this may seem obvious to those of you not in health care, specifically academics, we tend to operate on the precautionary principle... Know every possible risk before taking a step. This obsession with starting perfect is what has hindered so much value. But where does it come from?
