Chapter 1

Good Is the Enemy of Great

§

The book begins with the idea that being good can stop a company from becoming great. When a business is doing reasonably well, it may stop pushing for deeper improvement.

Collins explains that greatness is not usually the result of one lucky decision. It is built through consistent choices, strong leadership, disciplined people, and clear focus.

This chapter encourages businesses to question comfort. A company must ask whether it is simply functioning or truly becoming excellent.

For clinics and service businesses, this is a useful reminder. Stable operations are good, but long-term excellence requires continuous improvement in patient experience, systems, team culture, and brand trust.
