Relating in business networks: Innovation in practice

Few studies have looked at the innovation process in the early stages of new business ventures in the context of business networks. Reporting on eight years of development of a new venture, we examine how the development of initial business relationships in an ever-changing business network affects technological innovation. We conclude that technological innovation is contingent on the development of business relationships that are a critical mechanism permitting a new venture not only to access but also to produce knowledge essential for innovating. For management this implies the need to strike a judicious balance between internal focus and closure to produce novel solutions and external focus and openness to experiment in business relationships.     

Embedding of a new business as a cumulative process of combining different but complementary types of projects: The case of a project-based firm

Within the industrial network approach, new business formation is a cumulative process of relating the new business to the existing business network over time. This paper combines the literatures on industrial networks and projects (management) to explore the roles of two different types of (temporary) inter-organizational projects in the embedding process. The paper examines the embedding in a network of a new project-based firm that went from being a new entity to becoming capable of taking a stronger network position by using different types of projects as embedding tools. Embedding of the new firm in the business network required the combining of different but complementary types of projects to build a stronger network position. We find that (temporary) inter-organizational projects are tools for embedding the firm in a network of relationships. The inter-organizational projects can provide the firm with opportunities to both discover and develop not only its own resources but also the resources of others, leading it to change perceptions and principles on what resources are useful to access and who possesses those resources.

Managing strategic system-building networks in emerging business fields: A case study of the Dutch smart grid sector

Companies that wish to launch innovative sustainability technologies can collaborate in strategic networks of actors from industry, government and research institutes to pro-actively build a business ecosystem around their new technology. This is called collective system building. In this paper, we examine how to effectively manage networks for collective system building. Based on a review of the literature, we identify the key factors of effective network management and we propose a conceptual framework for network management at the network level. Subsequently, we conduct a multiple-case study in the Dutch smart grid sector to examine how these key factors are implemented by system-building networks. We find differences with the existing network management literature regarding network composition, network management structure, governance modes, decision-making processes, project management, the free-rider problem and trust-building mechanisms. Our study contributes to a better understanding of effective management of system-building networks, which in turn can lead to greater success in establishing new business fields. We contribute to the literature on strategic business networks, specifically on emerging business networks building new business fields.     

Business ecosystem strategies of mobile network operators in the 3G era: The case of China Mobile

In order to define the mobile network operators' strategies of building value network in the 3G era, this paper applies the ecosystem principles to the mobile industry through a China Mobile case study. Based on an analytical framework of such principles, this paper reviews China Mobile's ecosystem, and identifies its success factors and problems. The results indicate that a complete ecosystem, where mobile network operators collaborate closely with value-added service providers, content/application providers, equipment and device manufacturers, and other involved organizations, can promote the development of mobile data services substantially. Therefore, mobile network operators should play a central role in the ecosystem by managing the entire value-chain and setting up proper value-sharing mechanisms. However, while doing so, problems may arise because of regulatory issues and information asymmetry. High-value common assets, a centralized management system, partner selection schemes and continuous innovations are important success factors.

Standardization Alliance Networks,Standard-Setting Influence,and New Product Outcomes*

Standardization alliances evolve through collaborations among firms for developing and implementing industry technical standards. Cooperative standard setting can help allied firms to gain access to external knowledge and technologies, but it is unclear how the configuration of a standardization alliance can result in improving a firm’s performance in new product development. This study examines how standardization alliance network-based resource advantages vary across a firm’s network position and the firm’s ability to influence industry standard setting and new product outcomes. Empirical analyses, based on archival data from 170 Chinese automobile manufacturers from 1999 to 2013, indicate that firms that span structural holes in standardization alliance networks gain an advantage when focusing on early new product introductions but suffer a disadvantage when aiming at more innovative products. In contrast, taking a central position in standardization alliance networks is negatively related to a firm’s speed in bringing new products to market but positively related to the firm’s new product introduction rate. Further, standard-setting influence significantly mediates the effect of network position on a firm’s new product speed to market. Increasing centrality and structural holes can lead to the improvement of a firm’s standard-setting influence, and this, in turn, positively affects speed to market.
