It covers the 3 basic risks that can derail any strategy: demand risk (no one will want your product or demand is higher than expected), competitive risk: other companies capturing the market and taking away customers and capability risk:that a firm is not able to deliver the value propositions that customers will pay for or the capabilities cost so much that it is unable to make a satisfactory profit. It also covers differentiation and low cost strategies. A rather insightful book w/ numerous business cases. I am taking notes on this book for future reference.
