This article identifies and theorises the interorganisational socialisation mechanisms that facilitate the knowledge dynamic capabilities of organisations brought together within the applied context of a U.K. Local Enterprise Partnership. Focusing on the Sheffield City Region's Creative and Digital Industries Sector Group, the data for this study were messages posted to the Creative and Digital Industries Sector Group's online consultation platform. Data analysis proceeded through inductive thematic analysis. It is revealed that collaborative workspaces, business networks resources, and pathways to internationalisation are perceived to play an important role in facilitating interorganisational learning. These knowledge socialisation mechanisms are essential to avoid regional competency traps. The article identifies and discusses knowledge socialisation mechanisms that are perceived to play a key role in transferring knowledge between members of the regional system of innovation. In identifying and discussing knowledge socialisation mechanisms, this paper offers knowledge management theorists and practitioners—more specifically, regional knowledge brokers and regional development managers—actionable insight into a range of strategies that reinforce social ties and increase the flow of knowledge with a view to improving innovation outcomes.
