Ever since his first book was published some six decades ago, Peter Drucker has been essential to everyone serious about the ''management of an enterprise (and) the self-management of the individual, whether executive or professional, within an enterprise and altogether in our society of managed organizations.'' This distinguished 30-year Claremont University professor has continuously identified critical principles in management, economics, politics, and the world in general. And he has redirected our thinking about them through more than two dozen books, including an autobiography and a couple of works of fiction. Now, with The Essential Drucker, he has overseen the compilation of his most important fundamentals into one indispensable book.Reaching back as far as 1954 with his treatise ''Management by Objectives and Self-Control'' (''Each manager, from the 'big boss' down to the production foreman or the chief clerk, needs clearly spelled-out objectives'' that clarify expected contributions ''to the attainment of company goals in all areas of the business''), Drucker's now-established ideas take on a surprising new relevancy when remixed equally pioneering ideas from the 1960s, '70s, '80s, and '90s. Between the thoughtful ''Management as Social and Liberal Art'' through the provocative ''From Analysis to Perception — The New Worldview'' (both originally published in 1988's The New Realities), this book revisits some of modern management's most inspired writing and presents it in a way that should appeal to both newcomers and those needing a refresher course on Drucker's basic beliefs
