Efficient technological strategy is an increasingly important element in industrial profitability. An understanding of networks - the formal and informal web of contacts between suppliers, producers and customers - is vital to the application of such strategy. In this book, first published in 1989, Håkan Håkansson brings together theory and practice to provide the first comprehensive and detailed study of technological development in companies, and the associated interactions with other companies and organizations. This book is ideal for students of business.
