Background: The gap between research and practical implementation remains a major challenge for policymakers. Research co-creation, involving researchers co-designing and co-producing research with industry, government and civil society, can support improved end user uptake and better research implementation. Aims and objectives: This Practice Paper introduces a process of research co-creation based in implementation science and integrated knowledge translation theories. It details the development of the Infrastructure Engagement Excellence Standards (IEE), a framework of 10 Standards defining the qualities of community engagement for optimal infrastructure planning and delivery. The paper details a research co-creation process applicable across a variety of industries and policy settings. Key conclusions: The Practice Paper introduces a theory-based method for research co-production and discusses strengths and weaknesses of the co-creation approach used to develop the IEE Standards. Implementation science and integrated knowledge translation theory offer important insights to support more successful research co-design and co-production. Research that incorporates these theories is better positioned to achieve implementation. The creation of the IEE Standards offers one helpful example of how researchers, policymakers and practitioners can begin to close the research-implementation gap.
