Our networks-and how we work them-create vital ties that bind. Organizations recognize and reward this fact by leaning ever more heavily on collaboration, particularly when it comes to getting new things done. This book offers a framework that explains how innovators use network processes to broker knowledge and mobilize action. How well they do so directly influences the outcome of attempts to innovate, especially when a project is not tied to prescribed organizational routines. An entrepreneur launches a business. A company rolls out a new product line. Two firms form a partnership. These instances and many more like them dot today's business landscape. And yet, we understand little about the social dimension of these undertakings. Disentangling brokerage from network structure and building on his theoretical work regarding tertius iungens , David Obstfeld explains how actors with diverse interests, expertise, and skills leverage their personal and intellectual connections to create new ventures and products with extraordinary results.
