Good to Great

What makes the differences between top performers and good performers? The author did a data analysis of companies that over‑performed the market for more than 15 years. He then tried to identify the key to their success. One answer is leadership—​not dictatorship. The author describes precisely what leadership means. It is a kind of parenting attitude that makes people autonomous while responsible. You need a leader, but also good people. People who are not passionate about what they do don’t have a place on the ship. There are two other factors, which are about discipline and the core business of the company. Even if two companies are in the same segment, doing approximately the same thing (for example, two banks), these factors make the difference.


Introduction

This book is about why some companies outperform the market.
The author selected several companies that outperformed the market for more than 15 years to avoid the luck effect.
He and his research team conducted interviews and questionnaires to understand why those companies succeeded while others did not.

The book is very easy and pleasant to read.
Concepts are well explained and illustrated with various large companies.
It is not about startups, so the discoveries for those companies may not apply to them.

The book is well structured.
The main ideas are presented first in each chapter, then illustrated by examples, and finally summarized in a two‑page recap.
You could read only those final pages, but the illustrations are helpful—​they always compare two companies in the same segment, showing why one failed while the other excelled.

Good is the Enemy of Great

The author started this research motivated by pure curiosity.
He performed the analysis in four phases:

  1. Search for “great” companies, selecting those that outperformed the market.
  2. Choose comparison companies from the same sector and evolving over the same period.
  3. Collect data—​all available articles and other sources—to understand what initiated the transformation.
  4. Develop ideas: discuss the data with the research team and clean it up to find the core drivers.

He identified three main characteristics that turned good companies into great ones:

  • Disciplined people
  • Disciplined thought
  • Disciplined action

The chapters are briefly described in one paragraph each.

The author underlines that because he studied companies over a long period and across different fields, the results are timeless and independent of the technology used.
It is mostly a human problem, not a business one.
The same concept could be applied to other “entities”: schools, newspapers, churches, government, etc.

Level 5 Leadership

The authors describe five levels of performance:

  1. Highly capable individual – someone with knowledge, talent, skills, and good habits.
  2. Contributing team member – contributes to a group by interacting with others.
  3. Competent manager – organizes people and resources to achieve defined goals.
  4. Effective leader – catalyzes commitment and shares a clear vision.
  5. Level 5 executive – builds enduring greatness with humility and will.

Great companies are often driven by Level 5 leaders.
They set aside ego and self‑interest and dedicate themselves to the company with ambition.
They are results‑oriented, rarely talk about themselves, and generally lead normal lives.

Sometimes they even say they are not necessary.
These leaders give autonomy and clear guidelines, so everyone knows what to do even when the leader is not present.
In the interviews, people described their leaders with words such as:

Quiet, humble, modest, reserved, shy, self‑effacing, …

When things go well, they look out the window.
When things go wrong, they look in the mirror.

Level 5 leaders can catalyze the transformation of lower‑level leaders into effective ones.

Leaders who put themselves first may select weak successors, leading to failure.
If an organization is too hierarchical, always accepting decisions from above, initiative never appears.
People need some freedom, to be recognized and respected; they are not children nor slaves.

Conflict is okay in a company as long as debate can occur to understand others’ positions.
However, if the louder voice always wins the debate, the process breaks down.

First Who … then What

During the transition, executives did not change the direction to take; they changed the people.
Assets are not people—they are good people.
A great vision without great people leads nowhere.
If you have the right people, it is easy to adapt.

Good people are:

  • competent
  • self‑motivated
  • endowed with human qualities

On the other hand, it is not advisable to have one genius and many helpers to implement his ideas.
If the genius leaves, only helpless helpers remain.
Geniuses are a type of Level 4: they would need to find what first, and then who would do it.

Pay does not really impact the outcome, nor does the compensation structure (stock options, salary, bonuses).
You need a minimal package, but putting more on the table won’t make people deliver more.
Level 4 leaders tend to earn more than Level 5 leaders, even though they may produce lower results.

Rigor doesn’t mean ruthlessness. The best people can concentrate on their work, not on office politics or fights.

Advice

  • If you are not sure when hiring, don’t hire.
  • If you need a people change, do it, even if it’s painful.
  • Put the best people on the best opportunities.

It is useless to hire many people and keep only the best after three years; that is not efficient.

Confront the Brutal Facts

Facts are better than dreams.
It is better to look at the future and possible new issues rather than dwell too long on past achievements.
What was true yesterday may no longer be true today; you need to adapt.

  1. Lead with questions, not answers. Let people think and propose different versions. Ask the three whys to fully understand the arguments, questions, and goals.
  2. Engage with dialogue and debate, not coercion. All voices are important. Seniority doesn’t guarantee better ideas; even interns can provide valuable insights.
  3. Conduct autopsies without blame. Learn from mistakes; blaming people does not help and can make them feel undervalued.
  4. Use “red flags.” All companies have access to the same information, but they manage it differently. A red flag is the right to highlight issues that cannot be ignored.

Stockdale Paradox – even when facing a crisis (the brutal fact), great leaders stay consistent and keep faith.

The Hedgehog Concept

The fox knows many things, but the hedgehog knows one big thing.

The fox is diffused, trying to do several things at once with different goals.
The hedgehog focuses: it simplifies a complex world into a unified vision.

Finding the core of a company is not straightforward; it can take up to four years.

Three circles help identify what you are good at:

  • What you can be the best in the world at
  • What drives your economic engine
  • What you are deeply passionate about

Great companies know the answer to the three questions and can translate it into a single concept/direction.

Also, consider what you cannot do better than other companies.

The hedgehog concept is not about being the best; it is an understanding of what you can be the best at.

The economic driver can be expressed as the variable you need to optimize:

  • € / person
  • Persons reached / mi²
  • Amount of steel processed
  • Number of ATMs or stores per area

The economic driver allows a deep analysis of the situation. Growth alone is not measurable and does not apply.

One hiring strategy is to select only people who are passionate about the company’s product or mission. Skills can always be learned; passion cannot.

Some pages (e.g., p. 104) explain how to run the analysis:

  • 5‑12 people, informal body, not a formal title
  • Each member must be able to argue
  • Members come from different branches of the company
  • The council belongs to the company; it is not an external group
  • Do not seek consensus: executives select ideas from the discussion.

A Culture of Discipline

Few startups become successful because they ignore the hedgehog concept.
People have a lot of imagination and try many things, but taking many directions prevents the creation of a strong foundation.

Typical symptoms:

  • Many products
  • Many markets/customers, each with a different reaching strategy

Result: disorganization, lack of planning, and weak commitment.

We need to avoid bureaucracy; innovation disappears when bureaucracy and hierarchy take over.
These two “stuff” compensate for incompetence and a lack of discipline.
Bureaucracy is both symptom and disease.

  Entrepreneurship Discipline
Bureaucracy Low Low
Hierarchy Low High
Startup High Low
Great organization High High

To have a great organization, culture must be oriented toward:

  • Freedom and responsibility
  • Self‑disciplined people willing to go further
  • Not confusing tyranny with discipline
  • Consistently adhering to the Hedgehog Concept

Great companies set rules and clear constraints while giving freedom.

Everyone wants to be the best; what prevents that is ego.

Anything that does not fit with our Hedgehog Concept, we will not do.

A great company is more likely to die from too many opportunities than from starvation. It must select the best opportunities.

Do you have a to‑do list? What about a not‑to‑do list?

If you couldn’t justify to your peers the need for at least fifteen people reporting to you to fulfill your responsibilities, then you would have zero people reporting to you.

Technology Accelerators

How can we use new technologies to enhance our current jobs?
Great companies become great when they figure out how to apply technology.

We must be careful about bubbles. Bubbles have always existed; we must not be fooled by them.
Great companies must not rely solely on bubbles; they select the most relevant technologies.

Mediocrity is often a management failure, not a technological failure.

Technology is a liability, not an asset. It is accessible to all.

Great companies focus on strategy—not merely competitive strategy—but first on their direction. They don’t wait for the competition to sink.

The Flywheel and the Doom Loop

Good‑to‑great transformation doesn’t happen in one day. It takes time to build momentum.
Companies become great thanks to cumulative effort.

Labeling the transformation doesn’t help; the substance matters.
The process must be continuous—it must not have a fixed end.
People become aware of the transformation when it is well underway.
Saying “we will put program X in place” will not make people feel the change or commit to it.

The doom loop occurs when a manager says, “let’s go in this direction,” tries to motivate the troops, then changes direction because results are not immediate. People tire after a few rounds, and progress stalls.

From Good to Great to Built to Last

One of the author’s previous books is Built to Last; this chapter connects the two works.

The research for Good to Great was conducted as if the previous book did not exist.

  1. Startups focus on getting off the ground, while great companies figure out how to transform established firms. Level 5 leaders appear in both.
  2. The Good‑to‑Great process precedes Built to Last.
  3. To transform into a Built‑to‑Last organization, the goal shifts from making money to pursuing a transcendent purpose.
  4. The two books are complementary.

BHAG – Big Hairy Audacious Goal.

In Built to Last, money is like blood flowing: it’s not scarce, so focusing on it alone is not the main objective.

There is a need to preserve core elements while changing others.

Key ideas:

  • Clock building, not time‑telling: focus on building a lasting system rather than merely tracking time.
  • Genius of AND: do not focus on only one thing; combine extremes—freedom and responsibility.
  • Core ideology: values that guide decisions and inspire people.
  • Stimulate progress: preserve the core while accepting change, innovation, and improvement.

Turning good into great takes energy, but it adds energy back, fueling motivation.
However, perpetuating mediocrity leads to stagnation.

Conclusion

Good people, clear vision, discipline.

These answers are not surprising, yet the book provides vivid examples and clear definitions.
