Overall the content is decent, but Time has given this book a black eye. Some of the companies touted as models to follow are in dire straits now or went out of business. Fannie Mae, praised as one of the banks to go Good to Great, has fallen into the trash heap since 2008 and has never recovered. This happened 7 years after the book was written. Circuit City, another Good to Great, doesn't even exist anymore, at least by name and as a brick-n-mortar store. Wells Fargo, a good to great awardee, aren't so noble anymore given their recent scandals. In the 2010's, Wells Fargo perpetrated some of the poor behaviors the book claimed they avoided through the 80's and 90's which led them to Great. The book is VERY well researched in its time frame, but a lot of it in my opinion is antiquated. 90% of the data is taken from the pre-Internet era, the ball field is much different now. Some of the points are valid and helpful, some are senseless. I did glean a few nuggets from the book that made it worth my time, but 1/3 of the way through this book I dreaded finishing it. You'd be better reading Simon Sinek's Start With Why.
