Overview

Why do some companies soar to greatness while others remain stuck in mediocrity? In Good to Great, Jim Collins investigates this question through one of the most rigorous research studies ever conducted in business. Over five years, Collins and his team examined 1,400 U.S. companies, identifying just 11 that transformed from average performers to long-term market leaders—and sustained that success for at least fifteen years.

The study revealed that greatness is not about luck or one-time innovation; it’s about consistent discipline, strong leadership, and unwavering focus. Great companies move forward gradually, not through sudden revolutions, but through small, steady actions that build unstoppable momentum.

The Quiet Strength of Level 5 Leaders

At the core of every great company is a special kind of leader—what Collins calls a Level 5 leader. These individuals are humble, reserved, and modest, yet they possess an extraordinary resolve to achieve lasting success for their organizations. Their ambition is not for personal fame but for the company’s enduring prosperity.

One powerful example is Darwin Smith, the unassuming CEO of Kimberly-Clark. In the 1970s, he made the bold move to sell the company’s paper mills and focus entirely on consumer brands like Kleenex and Huggies. Many thought he was crazy, but his quiet confidence and clear vision transformed Kimberly-Clark into an industry leader that outperformed even Procter & Gamble.

Similarly, Colman Mockler of Gillette led the company through repeated takeover attempts. Instead of cashing out, he reinvested heavily in research and development, producing cutting-edge razors that kept Gillette at the top of the market for decades.

These leaders share a paradoxical blend of humility and determination. They take the blame when things go wrong, credit others when things go right, and never allow ego to interfere with the company’s mission. Their leadership is quiet, persistent, and transformational.

Building a Great Team Before Building a Strategy

Collins found that great companies start not with a vision or strategy, but with the right people. Before deciding where to go, they make sure the right people are on board—and the wrong people are not. Once the right team is in place, direction becomes clear and adaptable.

Wells Fargo exemplified this during the deregulation of the banking industry. Instead of chasing growth through risky acquisitions, the company focused on recruiting disciplined, capable individuals who could navigate uncertainty. When the industry shifted, Wells Fargo thrived while competitors like Bank of America stumbled.

The key insight is simple: the right people don’t need micromanagement or excessive motivation. They are self-driven, committed to the mission, and capable of steering the company through change. Strategy evolves, but great people are the foundation that keeps a company resilient.

Facing Harsh Truths Without Losing Hope

A defining trait of good-to-great companies is their ability to face uncomfortable facts while maintaining faith in their ultimate success. Collins calls this mindset the Stockdale Paradox, named after Admiral James Stockdale, a Vietnam POW who survived years of torture by combining brutal realism with unbreakable optimism.

In business, this means acknowledging failures, market threats, or internal weaknesses—without losing confidence in the company’s long-term vision.
