In his early career, Mintzberg was described as the “enfant terrible of strategy”. The Canadian business school professor has made a career out of looking at things differently. He started out by actually looking at what managers do. In The Nature of Managerial Work (1973) he revealed that managers flitted from task to task with the concentration span of gnats. Nothing much had changed when Mintzberg revisited this subject decades later in Managing (2009).
