Technical innovation in industry is regarded by many people as the best way of making industry more profitable. A great deal of energy and time is being expended by businessmen and by governments discussing how best to bring about technical innovation. This book, which was first published in 1987, argues that all concerned with technical innovation should bear in mind the importance of 'networks'. 'Networks' are defined as the web of contacts which exist between suppliers, customers, and producers in industry. Drawing on extensive original research, the book discusses the need for co-ordinating technical research and development with suppliers and customers and examines in detail how this should best be done. This book is ideal for students of business and economics.
