What It TakesMinorities in the Executive Suite Research by David A. Thomas and John J. Gabarro Volume III, Number I We are on the cusp of a new millennium; yet the face of corporate power in the United States remains overwhelmingly white. People of color hold less than one percent of all senior executive posts. But what about leaders such as Kenneth Chenault, president and chief operating officer of American Express; Solomon Trujillo, president and CEO of US West Communications; and Ann Fudge, president of Maxwell House Coffee Company and Post Cereals? How did these people of color overcome the odds and break through the glass ceiling that hangs over the heads of most minority managers in large U.S. companies? In their book, Breaking Through: The Making of Minority Executives in Corporate America (HBS Press: 1999), two HBS faculty members, Professor David Thomas and Professor John Gabarro, explain that the road to success for such corporate leaders takes them through some difficult twists and turns. Promotions, for instance, are typically much harder to come by in the early stages of their careers than they are for whites. And once they make the leap into middle and upper management, these trailblazers have to put together a stellar record of performance while building a network of mentors to support and advise them.To uncover the processes that promote the development and advancement of minority executives, Thomas and Gabarro embarked on a six-year study analyzing promotion data and then comparing the career experiences of 54 minority and white executives and managers from three companies. Masked by the pseudonyms Acme Industries, Gant Electronics, and Advanced Technology, these firms represent very different industries, products, and cultures, but they all share a commitment to diversity and a record of promoting people of color to leadership positions. Minority managers are promoted only after proving themselves again and again.
