Platform owners develop boundary resources to transfer design capabilities to third-party developers and boost innovation within platform ecosystems. The literature on boundary resources suggests the concept of tuning to depict the process where such resources are shaped through an interactive process involving platform owners, third-party developers and other actors within the platform ecology. While the literature on the tuning of boundary resources is promising and emerging, there is to our knowledge no current studies on platform owners’ measures to speed up this often prolonged process. In this research, we studied how a platform owner sought to accelerate the tuning process of its boundary resource through a case study at Volvo Group Truck Technology. In doing so, Volvo used an innovation contest where third-party developers used several boundary resources and engaged in an accelerated tuning process with Volvo Group Technology.
