This landmark book draws on Henry Mintzberg's observations of twenty-nine managers, in business, government, health care, and the social sector, working in settings ranging from a refugee camp to a symphony orchestra. What he saw-the pressures, the action, the nuances, the blending-compelled him to describe managing as a practice, not a science or a profession, learned primarily through experience. This book is vintage Mintzberg: iconoclastic, irreverent, carefully researched, and myth-breaking.
