For business and nonprofit leaders, policymakers, and academics, Porter (Harvard Business School) collects 15 articles he wrote for Harvard Business Review between 1979 and 2008, on topics relating to competition and value creation, with seven new articles in this edition on health care, philanthropy, leadership, and corporate social responsibility. Sections address competitive advantage, including the five forces and strategic positioning; the role of location, including his "diamond theory"; using strategic thinking in addressing societal issues such as environmental sustainability and income inequality; the application of strategy by nonprofits and corporations as a means of philanthropy; and leadership. The essay on competitive forces that shape strategy has been revised. Annotation ©2009 Book News, Inc., Portland, OR (booknews.com)
