"[...] Das Besondere an diesem Buch sind jedoch nicht die Inhalte, sondern es ist die Art der Vermittlung von Know-How und Praxiswissen. Lencioni gelingt dabei das Kunststück, Sachinformation in ein packendes Fallbeispiel zu verpacken - eine Eigenschaft, die er mit vielen amerikanischen Autoren teilt. Das erleichtert die Identifizierung des Lesers mit den Erkenntnissen und sorgt fü eine ganze Reihe von Aha-Erlebnissen.[...] Dankenswerterweise lässt Lencioni den Leser dabei nicht allein mit einer spannenden Prosa, sondern liefert zudem auch Hinweise zur praktischen Realisierung des Erlernten."
