Good to Great is an excellent book, filled with fascinating insights for the business leader, or anyone striving to make their organization "Great". This book is a MUST READ before implementing the next big change or improvement program in your business, or hiring the next key-person. It is a must-read for anyone wanting to build a great company as well... Having the author narrate adds to the content & message of the book as well. Having Collins narrate allows him to place special emphasis on things particularly important to him, as well as offer his commentary & reflections, that most certainly would not exist if the publisher used a 3rd-party narrator. Also, in this audio version, Collins give his insight into the work several year after the book's publishing, which only reaffirms, or sheds new light, or clarifies certain points throughout the book. He even goes so far as to include several "Frequently Asked Questions" since the book's initial publishing, and offers his insight to these questions as well. I must also address some of the negative reviews about the book as well. Since publishing, some of the companies discussed in the book have fallen from their "Great" status, and several people have dismissed the book because of that. However, Collins addresses this very point in the epilogue of the book - at the time of it's initial writing - pointing out that "IF" a company were to lose it's "Great" status, it would not negate the findings of the research, and the book itself. Fixating on the long-term success after the "Good to Great" research totally misses the point - a point which Collins very clearly addresses near the end. In short, this is an absolute MUST READ for people wanting to initiate change in their business, or simply for those wandering "what makes some businesses great," or "can my business become great...?" Good to Great is an absolute must read - I cannot recommend it more highly.
