Query: A facinating read and a superb reference

As a business consultant in the area of biotech I found the book exceptionally useful. Rogoff's book was the most important reference for me when we wrote our business plan; I go back to it often when I review business plans of bio-medical start-ups.I highly recommend it to entrepreneurs (both experienced and beginners) and MBA students focusing on various industries.
