Drawing on more than fifteen years of consulting experience - and on in-depth interviews with top executives and analysts - Cohan takes an up-close look at twenty of America's leading high-tech companies. In no-nonsense language, Cohan outlines and explains a framework for success based on the four sources of advantage that drive these companies' superior performance: entrepreneurial leadership, open technology, boundaryless product development, and disciplined resource allocation. He details new ways to structure and manage organizations, processes, and alliances so businesses can increase their levels of innovation and get competitive products to market more quickly. Most importantly, he provides a detailed road map that will help managers across all industries adopt the best practices of the nation's technology leaders for their own organizations.
