New input: Insightful and Hilarious . This is a unique and hilarious book on 23 models that the author, Adrian Slywortzky, presents for improving the profitability of a company. The author methodically presents an insightful story in each chapter enabling the reader to gain an appreciation of the 23 models through parables and hilarious stories. The author did a good job of transforming a rather dry subject into something interesting which both the veteran in accounting and the novice will find enjoyable and enlightening. The reader is made to reflect and think about their business which makes the book unique and useful. As soon as I got the book, I swallowed it in three days and I have to admit that it was extremely tasty and satisfying. This is a useful book for all people running businesses and those intending to do so.

POS
