The good-to-great examples that made the final cut into the study attained extraordinary results, averaging cumulative stock returns 6.9 times the general market in the fifteen years following their transition points.
Larger-than-life, celebrity leaders who ride in from the outside are negatively correlated with taking a company from good to great. Ten of eleven good-to-great CEOs came from inside the company, whereas the comparison companies tried outside CEOs six times more often.
We found no systematic pattern linking specific forms of executive compensation to the process of going from good to great. The idea that the structure of executive compensation is a key driver in corporate performance is simply not supported by the data.
Strategy per se did not separate the good-to-great companies from the comparison companies. Both sets of companies had well-defined strategies, and there is no evidence that the good-to-great companies spent more time on ...
This highlight has been truncated due to consecutive passage length restrictions.
The good-to-great companies did not focus principally on what to do to become great; they focused equally on what not to do and what to stop doing.
Technology and technology-driven change has virtually nothing to do with igniting a transformation from good to great. Technology can accelerate a transformation, but technology cannot cause a transformation.
The good-to-great companies paid scant attention to managing change, motivating people, or creating alignment. Under the right conditions, the problems of commitment, alignment, motivation, and change largely melt away.
The good-to-great companies had no name, tag line, launch event, or program to signify their transformations. Indeed, some reported being unaware of the magnitude of the transformation at the time; only later, in retrospect, did it become clear. Yes, they produced a truly revolutionary leap in results, but not by a revolutionary process.
Level 5 Leadership. We were surprised, shocked really, to discover the type of leadership required for turning a good company into a great one. Compared to high-profile leaders with big personalities who make headlines and become celebrities, the good-to-great leaders seem to have come from Mars. Self-effacing, quiet, reserved, even shy—these leaders are a paradoxical blend of personal humility and professional will. They are more like Lincoln and Socrates than Patton or Caesar.
First Who . . . Then What. We expected that good-to-great leaders would begin by setting a new vision and strategy. We found instead that they first got the right people on the bus, the wrong people off the bus, and the right people in the right seats—and then they figured out where to drive it. The old adage “People are your most important asset” turns out to be wrong. People are not your most important asset. The right people are.
The Hedgehog Concept (Simplicity within the Three Circles). To go from good to great requires transcending the curse of competence. Just because something is your core business—just because you’ve been doing it for years or perhaps even decades—does not necessarily mean you can be the best in the world at it. And if you cannot be the best in the world at your core business, then your core business absolutely cannot form the basis of a great company. It must be replaced with a simple concept that reflects deep understanding of three intersecting circles.
A Culture of Discipline. All companies have a culture, some companies have discipline, but few companies have a culture of discipline. When you have disciplined people, you don’t need hierarchy. When you have disciplined thought, you don’t need bureaucracy. When you have disciplined action, you don’t need excessive controls. When you combine a culture of discipline with an ethic of entrepreneurship, you get the magical alchemy of great performance.
Yes, the world is changing, and will continue to do so. But that does not mean we should stop the search for timeless principles. Think of it this way: While the practices of engineering continually evolve and change, the laws of physics remain relatively fixed. I like to think of our work as a search for timeless principles—the enduring physics of great organizations—that will remain true and relevant no matter how the world changes around us. Yes, the specific application will change (the engineering), but certain immutable laws of organized human performance (the physics) will endure.
Smith, the company’s mild-mannered in-house lawyer, wasn’t so sure the board had made the right choice—a feeling further reinforced when a director pulled Smith aside and reminded him that he lacked some of the qualifications for the position.2 But CEO he was, and CEO he remained for twenty years.
Darwin Smith stands as a classic example of what we came to call a Level 5 leader—an individual who blends extreme personal humility with intense professional will. We found leaders of this type at the helm of every good-to-great company during the transition era. Like Smith, they were self-effacing individuals who displayed the fierce resolve to do whatever needed to be done to make the company great.
Level 5 leaders channel their ego needs away from themselves and into the larger goal of building a great company. It’s not that Level 5 leaders have no ego or self-interest. Indeed, they are incredibly ambitious—but their ambition is first and foremost for the institution, not themselves.
