Drucker identifies and explains the practices, decisions, and priorities for achieving business performance and executive effectiveness. The books cover "the three dimensions of the successful practice of management." Managing for Results was the first book to explain business strategy. Drucker shows how the existing business has to focus on opportunities rather than problems to be effective, for it is the opportunities that will bring growth and performance. Innovation and Entrepreneurship analyzes the challenges and opportunities of America's new entrepreneurial economy. It is a superbly practical book that explains what established businesses, public service institutions, and new ventures have to know, learn, and do to prepare and create the successful business of tomorrow. In The Effective Executive, Drucker discusses the five practices and habits that must be learned for executive effectiveness. Ranging widely through business and government, he demonstrates the distinctive skill of the executive and offers fresh insights into old and seemingly obvious situations. Together these three books have sold more than a million copies; they have been published throughout the world and continue to sell actively. (text from the publisher)
