This book looks at the motivation, culture, and ingenuity behind bringing the Nano to market in India. The design, manufacturing, and sales processes are all discussed in enough detail to be interesting, but not so much as to require the reader to be an expert in any of the above in order to be able to understand the struggles and glean lessons.
I suspect that the authors paint an overly rosy picture of Tata and his company, but this appears to be out of a desire to emphasize the good rather than an intent to mislead. I don't think that this bias hurts their conclusions. I work for a company that requires constant innovation in order to survive, and I saw much value in the argument that creativity is encouraged in an environment where allowing employees have the freedom to fail.
Its accessible writing style and many pictures make it a quick read, despite being a hefty 500 pages. The book's biggest fault is that it tries to turn every chapter of the Nano saga into a nice, neat moral lesson. By the end of the book, these lessons seem predictable and lengthy. Had they been more concise, the book could have been slimmed down by 100 pages or more without losing any discussion.
Overall, the story is interesting. The book is worth the read, especially for anyone interested in fostering creative thinking in a corporate environment.
