“Understanding Organizations … Finally!” by Henry Mintzberg is a book that will transform how you think about organizations, not because it says anything radical, but because its conclusions are so robust, you’ll wonder at how you ever got along without it./1/ With this book Mintzberg has reworked and updated his 1979 classic “The Structuring of Organizations”./2/ Given that Mintzberg has studied organizations as professor of management at McGill University for over fifty years, its title is quite modest. If he has “finally” understood organizations, we ought to pay attention. I nevertheless waited in vain for a discussion of lean and agile methods and how they fit within his framework. So, in this review, I will try to figure out why, as the readers of Teamworkblog may have similar questions.
