This book is similar to ‘outliers’ by Malcom Gladwell. Camblel takes several case studies from sports and politics in which people have employed fairly straight forward and simple techniques to succeed at the highest levels. There are examples of campaign managers, for Obama v’s Clinton, and their use of data and analytics. A look into team sky and their usage of ‘marginal gains’ to dominate the sport. It is interesting to read but if you have already read the books I have previously reviewed then it may be a refresher on some principles with different case studies rather than some ground breaking concepts and theories..
