'A world-class business education in a single volume'... a big claim on the front cover, and one that is only partly fulfilled. Once I'd forgiven Kaufman his very extensive rant against the formal MBA programmes (one which is very geared towards the uber-corperate USA model and ignores the much more valuable workplace based experience of many of us who have done UK based MBAs) I did enjoy the broad range of subjects covered, and the concise breakdown of a variety of management theories and concepts. It is a very simple and simplistic approach to a complex subject, and does pack a huge amount of material into a relatively short and readable form. Kaufman is a huge fan of 'book based learning'; this work is result of a serious amount of time spent trawling and cherry picking from the best literature, articles, blogs, and research. He's done a lot of the hard work here for us; the list of suggested reading looks very impressive and interesting.
My criticism of the book, is that there's very little real life application. It's very thin on case studies, or encouragement to apply to your own situation... ironically it was this element that I loved the most in my 'real' MBA experience. And for a man who loves his 'book learning', there is an annoying lack of academic referencing to the many useful theories and concepts that he presents. Evidence as to which of these theories might be more useful or proven is also lacking - but Kaufman's own intuition for these things seems to be good, and certainly has earned him a lucrative career! One thing that Kaufman admits to creating himself, and an exception to my criticism about lack of application, is the excellent exercise right at the end of the book '49 questions to improve your results' which is a polished model of reflective practice.
In summary: a good read, a good introduction to a panoply of management concepts, a fantastic resource to crib from if you're doing consultancy type work, a good refresher if you're feeling a little stale in you're own management practices and want some new ideas - but really no substitute for a properly applied MBA programme where you engage with real people in the real world.
