This text aims to help managers improve their research and development management and decision-making. It discusses best practices, as well as nine principles of smart R&D, and includes a section on testing how good an organization's R&D is.
This book was first passed to me by Cliff Penton when I was at Sophos. I thought it was a great read then, and it still is. But I guess it is a bit academic to ever really go down as one of the great business books of our time.
