Hambrick 'Insightful . . . reminds us why and how expertise matters' Herminia Ibarra What makes a great leader? This is the question Amanda Goodall has been asking for the last twenty years. From boardrooms and F1 race tracks to healthcare and scientific innovation, her research has proven time and again that when it comes to leadership, we need bosses with a deep understanding of the worlds in which they operate. That's what makes the people around them feel happier, more motivated and productive.
