The Firm: The Story of McKinsey and Its Secret Influence on American Business by Duff McDonald

A look at the history of the most prestigious management consulting firm of McKinsey. I thought the author did a fine job tracing the company’s origins and how it evolved and led corporations throughout the century. The company was highly selective with their clients. They also made it a point to only engage with upper management and decision makers within the company.

Above all, McKinsey seems to have a history of maintaining professional values with a few key exceptions (relating to Enron and insider trading by one of its executives). This book will not teach you how to be a top tier consultant. But it does provide a descent overview of one of the most influential organizations of our time.
