This is an incredibly interesting book about innovation, easy to read, clear and well articulated. A truly inspiring book in how to create value for people based on real data, not in supposed gurus or geniuses. An economy based on knowledge is possible, and it is the only sustainable way forward. I highly recommend this book to anybody working in emerging markets. It will open your eyes to an entire new range of new opportunities. I believe Eric Ries 'stepping on the shoulders of giant' Steve Blank has discovered to us a new way to see the world, a new way of learning how to see.
