Collins and a team of researchers spent five years analyzing 1,435 companies to find those that made the transition from good to great, defined as sustained stock returns at least three times the general market for at least fifteen years after a transition point. They identified eleven companies that met the criteria, then compared each one to a carefully selected comparison company in the same industry that did not make the leap.
Several findings came out of the research. The leaders of the great companies tended to be quiet, determined, and humble, not the charismatic celebrity CEOs that business media favors. Collins calls this “Level 5 Leadership.” The great companies also did not start with a grand strategy. They started by getting the right people (and removing the wrong people), then figured out where to go. Collins sums this up as “first who, then what.”
Other concepts from the book include the Hedgehog Concept (finding the intersection of what you can be best at, what drives your economic engine, and what you are deeply passionate about), the Flywheel Effect (success comes from consistent effort in one direction, not from a single dramatic breakthrough), and the Stockdale Paradox (maintaining absolute faith that you will prevail while simultaneously confronting the brutal facts of your current situation).
Some of the specific companies Collins highlighted, like Fannie Mae and Circuit City, later failed spectacularly, which critics have used to question the methodology. Collins addressed this by noting that the research measured specific periods of performance and that no company stays great forever.
For founders, the most immediately useful ideas are about hiring (get the right people first), about patience (the flywheel takes time), and about honesty (confront brutal facts rather than ignoring them). The book is well-organized, clearly written, and has sold over four million copies. It remains one of the most-cited business books in boardrooms and startup pitch decks, even twenty years after publication.
