Inbound open innovation for enhanced performance: Enablers and opportunities

Open innovation, defined as a firm's purposive pursuit and integration of external inputs for new product development, offers an alternative perspective on innovation. Drawing on resource-based and capability theories, this study identifies key factors that enable inbound open innovation and increase its efficacy in a business-to-business context. Because open innovation relies on external connections, relational capability—that is, the firm's ability to make and manage relationships with other firms—should enhance the effects of inbound open innovation on firm performance. Two key resources may further enhance the moderating effects of relational capability: network spillovers that indicate knowledge-rich surroundings, and flexibility that allows for responsiveness and adaptability. The authors test these relationships with data from managers in 204 business-to-business high-tech firms, as well as secondary data pertaining to firm performance and flexibility. The results support the expectations that the ability to build interfirm relationships in a knowledge-rich environment increase the efficacy of inbound open innovation for gaining superior financial performance. Interestingly, additional analyses suggest an unexpected nonlinear interaction effect with flexibility. When firms possess strong relational capabilities and adopt an open innovation approach, they achieve higher financial performance if they have a low or a high level of flexibility. The theoretical and managerial implications of these findings are discussed.

► Firms following open innovation can increase performance gains when maintaining a high level of relational capability.
► Performance gains are further enhanced when an environment of network spillovers exists.
► Managers should monitor resource slack to ensure adequate levels are available in order to respond to external opportunities.
► If the requisite level of slack is unobtainable, firm performance can be increased by deploying underutilized slack.
