What is it that great management teams do? How do they create sustained competitive advantage? In Purpose, Nikos Mourkogiannis turns the entire idea of strategy on its head, presenting a model that will redefine the way we do business. Strategy is typically thought of as management’s plan for a company, but Mourkogiannis argues that companies must satisfy the need for purpose–a set of values that defines a company and inspires its employees. Rather than organization and structure, ideas are what determine a company’s success. This groundbreaking book looks at companies like WalMart, IBM, and Berkshire Hathaway, identifying the ideas that point the way toward excellence.
