The Innovator's Dilemma: When New Technologies Cause Great Firms to Fail

The book that gave us the language to talk about why great companies fail. Clayton Christensen, the Harvard Business School professor who died in 2020, showed that well-managed companies lose their market leadership not because they make mistakes, but because they do everything right: they listen to customers, invest in improving their products, and focus on profitability. The problem is that this rational behavior blinds them to disruptive technologies that start small and cheap, then improve until they swallow the market whole.

Why Start Here

The Innovator’s Dilemma is the foundation for nearly every serious conversation about innovation in business. Before Christensen, disruption was just a word. After this book, it became a framework that explains patterns across industries from disk drives to steel mills to excavators. Steve Jobs called it the only business book that deeply influenced him.

What makes the book enduringly valuable is its counterintuitive core insight: doing what your best customers want is often the fastest path to obsolescence. Christensen does not just describe the problem. He provides a theory for why it happens and what managers can do about it. The research is rigorous, the examples are detailed, and the implications are uncomfortable in the best possible way.

What to Expect

A research-driven business book that reads like a series of detective stories. Christensen builds his argument methodically through case studies, primarily from the disk drive industry, then extends his theory to other sectors. The prose is academic but clear. Expect to underline passages and rethink assumptions about your own industry.
