This book is more about business philosophy than about strategy.
The basic concept is simple: Instead of focusing on the technological, operational aspects of the business, or even the final products, rather focus on what type of service you’ll be providing, how does it meet the customers’ needs, and wants and how can you streamline your business to provide more value to the customers (in terms of functions delivered and purposes served).
The book recounts stories of many businesses that have implemented this philosophy successfully. However, it does not provide any “actionable” guideline or process which, if you execute properly, will enable you to build a successful business.
