Social networks and word-of-mouth marketing are increasingly important, yet few current practices are based on a deep understanding of how the structure of networks can affect customer behavior and marketing outcomes. This chapter offers some critical observations on current word-of-mouth marketing practices and identifies four key questions that managers need to ask themselves before engaging in campaigns designed to leverage customer networks: Can we be confident that interpersonal influence or social contagion is really important? Why exactly would social contagion occur? Should we target key influentials? Can we identify and target those influentials? The answers to these questions cannot be taken for granted.

Zott and Amit explore the role of business models in creating value through networks. They review earlier, firm-centric views of value creation, including Porter’s value chain, the resource-based view, and the transaction costs approach. They point out that business models go well beyond classic views of network theory (e.g., topography and structure) and include notions of purpose, acceptance, fairness, coherence, and viability. Based on their earlier framework for e-business models, they explore the role of four major interlinked value drivers: efficiency, complementarities, lock-in, and novelty. They argue that the focal firm’s business model acts as both an engine for value-creation and an invaluable construct for understanding the firm’s role in relation to other business model participants in the networks in which it is embedded.

Global networks of firms are rapidly replacing top-down, hierarchical organizations. Such networks, thanks to information technology and global communications systems, can respond to changes in international demand faster and more flexibly than rigid corporate organizations of the past. But by drawing together diverse cultures and individuals, these networks present new challenges to leaders. Traditional styles of leadership are not enough for this emerging environment. The kind of leadership style that leads to efficient execution in these global networks is different from the “do it and do it now” approach that might work in hierarchical organizations. Based on the author’s experience in the leading global accounting firm Touche Ross, serving as dean of the Wharton School, and heading his own corporate investment firm, this chapter discusses leadership in a networked, global environment.

Networks increase interdependencies, which creates challenges for managing risks. This is especially apparent in areas such as security and enterprise risk management, where the actions of a single player in an interconnected network can wreak havoc on everyone in the network. The network, in this case, is only as strong as its weakest link. There are related problems in encouraging investments for prevention and protection, because the expected payoffs from such measures by one player are affected by the actions of other players in the network. This chapter examines the challenges of interdependent security (IDS) and strategies for addressing these, including coordination with broader networks such as industry organizations and government.

The locus of innovation is shifting from the firm to the network. In contrast to developing standalone products, innovators are drawing together networks that deliver a personalized, co-created experience to the customer. This chapter describes a model in which nodal firms link communities of customers with communities of prequalified vendors. It examines cases from cardiac pacemakers to addressing diabetes and explores the implications of this shift for product and service innovation, value creation, and new sources of competitive advantage.

In an environment of rapid and discontinuous change, managers have turned to alliances to access the resources they need. But research on alliances shows that more than half fail, demonstrating the difficulty of managing these relationships. Based on their extensive research on alliances, the authors explore the relational capabilities needed for building and managing successful alliances. Using the case of Royal Philips, they explore the role of strategy, structure, systems, people, and culture in alliance success. They also discuss the need for ongoing adaptation and renewal of relational capabilities as the business and its environment change.

Networks define modern business. Networks introduce new risks (as seen by the rapid spread of contagion in global financial markets) and opportunities (as seen in the rapid rise of network-based businesses). While managers typically view business through the lens of a single firm, this book challenges readers to take a broader view of their enterprises and opportunities. This book’s 28 original essays include CK Prahalad on networks as the new locus of competitive advantage Russell E. Palmer on leadership in a networked global environment Dawn Iacobucci and James M. Salter II on the business implications of social networking Franklin Allen and Ana Babus on contagion in financial markets Steven O. Kimbrough on artificial intelligence, evolutionary computation, and networks Satish Nambisan and Mohan Sawhney on tapping the “global brain” for innovation Manuel E. Sosa on coordination networks in product development Christophe Van den Bulte and Stefan Wuyts on customer networks Christoph Zott and Raphael Amit on using business models to drive network-based strategies Yoram (Jerry) Wind, Victor Fung, and William Fung on network orchestration Valery Yakubovich and Ryan Burg on network-based HR strategy Howard Kunreuther on risk management strategies for an interdependent world Paul R. Kleindorfer and Ilias D. Visvikis on integrating financial and physical networks in global logistics Witold J. Henisz on network-based political and social risk management Boaz Ganor on terrorism networks And much more...

Telecommunications is a networked business, yet it traditionally has resisted a network-based view in its strategies and business models. In this chapter, Kevin Werbach explores this paradox, contrasting the worldview of Monists such as AT&T, who see the infrastructure as inseparable from the network, and Dualists such as Google, who see the network and its applications as distinct from the underlying infrastructure. Not surprisingly, AT&T is a proponent of “tiered access” whereas Google argues for “network neutrality.” Finally, Werbach examines how a more modular future might bridge the gap between those who seek to own and capitalize on the network and those who seek to expand it through more neutral offerings.

Although any manager would recognize the importance of “networking” in finding, developing, and retaining employees, human resource management traditionally has focused on individuals. In this chapter, the authors point out that core HR processes such as recruitment and hiring, training and development, performance management, and retention all depend on networks. They consider the importance of weak ties in matching employees with jobs and “structural holes” in promoting creativity. They urge managers to make the shift from an atomized view to a network view of human resources--from focusing on the “trees” to understanding the “forest.” They show that networks can boost efficiency and productivity by facilitating information sharing, attracting talent, and strengthening employees’ commitment to the firm. But networks may also pose risks such as “lift-outs,” in which a departing employee takes other workers in his or her network. The authors explore how managers need to understand the impact of networks and how to “manage” them.

As manufacturing supply chains have moved from vertically integrated factories to diffused networks, manufacturers need to manage complex, global webs of suppliers. In this chapter, Netessine examines supply networks in two industries in particular: automobiles, and aerospace and defense. He explores how different strategies and technologies have helped companies manage, organize, and capitalize on their networks of suppliers. He discusses how Japanese automakers have used partnerships to outperform their U.S. rivals, who have taken a more adversarial approach to their suppliers. He also considers how companies such as Airbus and Boeing have used technology to coordinate and integrate far-flung networks. While Netessine notes that the formal study of network-based supply chains is just emerging, he offers insights from research and practice on the growing importance of supply networks and strategies for managing them successfully.
