"While there have been several books about Peter Drucker and his life, this is the first to present a comprehensive synthesis and in-depth analysis of his works and insights on management. Drawing from over forty years as a student, follower, and friend, John E. Flaherty has created a definitive account of Drucker's managerial achievements. An expert on management himself, Flaherty provides readers with a practical overview of Drucker's most important contributions to management and business strategy. He not only captures Drucker's fundamental management concepts and ideas but also shows how these principles have current relevance for today's practitioners."--Jacket.
