The Firm

Founded in 1926, McKinsey & Company has become one of the world's leading management consulting firms, helping to invent American business and shaping its course for decades. Ushering in the age of American industrial dominance, McKinsey remapped the power structure in the White House, helped create the bar code, revolutionised business schools, and introduced the idea of budgeting as a management tool. McKinsey consultants have people in the world. With unrivalled access to company documents and current and former employees, Duff McDonald reveals the inner workings of what just might be the most influential private organisation in America.
