In the decade since Fred Wiersema coauthored the #1 bestseller The Discipline of Market Leaders, a momentous shift has occured. We have entered an age of customer scarcity--an age in which exciting, often unorthodox companies are revolutionizing the global marketplace. In this path-cutting work, Wiersema provides new benchmarks for ranking businesses in this new economy and reveals the strategies that set winning companies apart. After tracking 5,000 companies worldwide for over six years, Wiersema discovered that just a few hundred of these of these exert tremendous influence on the new economy. Here, he explains why traditional measures of competitive prowess no longer apply and, using new yardsticks, identifies today's 100 most influential businesses. With practical strategies for managers and investors, Wiersema then shows how to recognize and emulate these dynamic new market leaders.
