The presentation focuses on the challenges of integrating external sources in the innovation process and investigates the role of environmental turbulence in this context. Building on the resources-based view and the dynamic capabilities perspective the authors propose that open innovation strategies assist companies in navigating through turbulent times. Empirical testing of this assumption in a sample of 101 industrial firms indicates that open innovation activities are more important in turbulent than in non-turbulent markets and supplier integration is vital when technological turbulence is high, whilst customer integration is critical in environments characterized by high market turbulence. From a practical point of view, these findings highlight the importance of stakeholder integration in the innovation process and provide details on the successful implementation of this strategy under different environmental settings.
