In 1914, Edwin Booz had an idea. He believed that companies would be more successful if they could call on someone outside their own organizations for expert, impartial advice. In doing so, he created a new profession — management consulting — and the firm that would bear his name, Booz Allen Hamilton. With more than 16,000 employees on six continents, Booz Allen generates annual sales of $3 billion. This historical section charts the evolution and highlights of the firm's 90 years of client service and continual development. Booz Allen Hamilton's clients are the world's largest corporations, emerging growth companies, government agencies, and institutions that want to change their organizations and the world for the better. Our clients — in every industry sector and every country — face daunting challenges. They need to manage ever-deeper and faster change. They need to understand how mega-trends like globalization, industry consolidation, and discontinuities in traditional markets and products affect their organizations.
