Good to Great

What is this book about?

Collins and his research team compare companies that made a sustained leap in performance with similar companies that did not, and identify patterns associated with the transition — level 5 leadership, first who then what, and the hedgehog concept.

Why read it?

It is a widely used case-based study of organizational change, and its methods — matched comparison, explicit criteria — are worth examining as an example of empirical management research. Later scrutiny of some sample companies makes it a good case study in how findings can decay.

Core Ideas

• Leadership that combines personal humility with professional will is associated with sustained results.
• Getting the right people on the bus precedes deciding where to drive.
• A hedgehog concept — the intersection of passion, best-in-world capability, and economic engine — focuses effort.
• Disciplined culture and disciplined action matter more than dramatic transformation programs.

What questions does this book try to answer?

• What turns an ordinary company into an exceptional one?
• Can research of this kind reliably identify causation?

Who should read it?

For managers and business-school readers. Read the critiques of its method and sample alongside it, so correlation is not mistaken for cause.
