Every year America becomes more diverse, but change in the makeup of the management ranks has stalled. The problem has become an urgent matter of national debate. How do we fix it? Frank Dobbin and Alexandra Kalev draw on more than thirty years of data from eight hundred companies as well as in-depth interviews with managers to show just how little companies gain from standard practice: sending managers to diversity training to reveal their biases, then following up with hiring and promotion rules, and sanctions, to shape their behavior. Almost nothing changes. It's time, Dobbin and Kalev argue, to focus on changing the management systems that make it hard for women and people of color to succeed. They demonstrate how the best firms are pioneering new recruitment, mentoring, and skill training systems, and implementing strategies for mixing segregated work groups to increase diversity. And they argue that as firms adopt new systems, the key to making them work is to make them accessible to all-not just the favored few. Powerful, authoritative, and driven by a commitment to change, Getting to Diversity is the book we need now to address constructively one of the most fraught challenges in American life.
