The absolute classic of theory of organization. The book reveals hidden assumptions made by the organizations' members, the beliefs of 'consultants' or researchers - and divides the presumptions into four separate categories (named 'paradigms' after Kuhn's specification). The authors brilliantly show, how the paradigms influence our perceptions and the ways we look at the organizations. All the approaches are fairly exemplified. The pros and cons of every paradigm become evident. A different light is shed on many famous theories and on the root methodology itself. The book should definitely be an obligatory lecture of management and sociology students - the managers and consultants can pick something for the as well.
