"This will be an important textbook in classrooms bringing together not only [Mintzberg's] own research and thoughts but also weaving in a century of writings by others. It will also reassure individual managers that what they do is important and not easy, and no doubt provoke some changes in their thinking." --Harry Schacter, Globe and Mail"This is an excellent, must-read book for managers and aspiring managers." --Mary Whaley, BooklistNamed one of Library Journal's Best of 2009 Business Books.Mintzberg calls attention to numerous popular but false views about the nature of managerial work, separates fact from folklore, and provides the best information yet published on what managers do and how they do it. He analyzes models, characteristics, and approaches to managing. He examines commonalities and differences in managing in various contexts, including business, government, health care, and social services. By shadowing 29 managers through a day in their lives, he reveals how managing is affected by many factors -- including national and industry cultures, organizational differences, level of the manager in the organization, and personal styles -- and examines the various strategies that managers adopt to deal with these factors. Mintzberg then identifies the main "conundrums" or dilemmas that managers must wrestle with (such as delegating versus retaining control, balancing order and flexibility, and gathering more data versus needing to take action) and describes how managers deal with those conundrums. And he offers provocative and powerful new understandings of what makes managers effective and ineffective.
