The Australian — Summary — Another “how–to–make–a–million” business book? Well, no. Winning Credibility by Matthew and Zbigniew Michalewicz is not designed to make you rich so much as to make your business work. The book addresses the catch–22s that paralyse businesses big or small, through a lack of credibility. People, Michalewicz says, can do a “credibility audit” to see how they stack up against the book’s suggestions. They can make realizations such as: “Yes, I’m strong in this area and have communicated it well to prospective customers, but I’m really weak here and have lost quite a few sales of because of it.”
