Professor Julian Birkinshaw is a renowned authority on the ambidexterity of incumbent firms that face disruptive innovations. His newest book, co-authored with Pearson’s John Fallon and entitled Resurgence, provides a roadmap for companies in this position. The core message is that AI and other disruptions need not create Kodak moments for large incumbents. Great firms can find strength in their portfolios of capabilities and build strategies to respond.
