Query: Deceiving book, Mediocre formulated and anodyne strategy

This is not a good business strategy book. The author develops with mediocrity his theory applied to business, which he considers to be revolutionary, to the point that includes a manifesto at the end of the book. The true is that It lacks of real and strong examples of companies that have succeeded by implementing the strategy of preventing broken windows, or in other words have paid attention to small details. If you want to read about anecdotes of poor service in many of the most famous American companies, you should buy this book, but if you do expect to read about an intelligent strategy that can yield long term results in your company, don't waste your time and money..
