How firms use inbound Open Innovation practices over time: evidence from an exploratory multiple case study analysis

Firms are increasingly making use of Open Innovation in an attempt to get the most out of external ideas and knowledge in their innovation processes. The existing research on Open Innovation documents a broad set of practices that firms may use to implement inbound Open Innovation, which entail various degrees of integration with the external partner. There is also empirical evidence showing how firms move from a closed to an open approach to innovation over time. However, there is limited empirical work that documents if and how firms that start using open innovation change and evolve the practices through which inbound open innovation is implemented over time. This paper, relying on an exploratory analysis of nine case studies, adopts a temporal perspective to examine how and why firms use different practices for inbound open innovation over time, with attempts at offering a tentative explanation of the underlying drivers triggering this evolution. This paper contributes to the scholarly debate on the organisational enablers of Open Innovation and provides managers involved in open innovation activities with insights into the factors that may determine changes in their use of different inbound open innovation practices over time.
