The Innovator’s Dilemma by Clayton M. Christensen is a seminal work that examines how successful, outstanding companies can do everything "right" yet still lose their market leadership—or even fail—as new, unexpected competitors rise and take over the market. Christensen introduces the concept of disruptive innovation, which explains how smaller companies with fewer resources can successfully challenge established businesses by targeting overlooked segments, then gradually moving upmarket. The book details why companies struggle with disruptive innovations and provides insights on how they can anticipate and adapt to these changes. It has become a must-read for business leaders and strategists aiming to navigate the complexities of innovation and change in their industries.
