is a fascinating exploration of the enigma of technological innovation. It provides a new paradigm for academic scholars and a manifesto for managers on how to release the latent talent of research teams for optimal effect. Based on an investigation conducted in the R&D laboratory of a Fortune 500 company, the book synthesizes interviews with sophisticated quantitative techniques to provide insights into how knowledge travels and how it is used in technical organizations to aid innovation. The author offers a new perspective on the factors that need to be taken into account when managing R&D projects, and examines particularly how these factors should be mobilized and combined in the quest for success. The book suggests that the informal advice relations need to be reinforced through, and not thwarted by, the formal structure. This is compulsory reading for anyone interested in the central problems of research and design in the knowledge industries of the twenty-first century.
