Co-production is a big buzzword in research at the moment. Anyone involved in social research - particularly in the fields of health and social care - has some appreciation of the value of and ethical imperative for knowledge that is produced in collaboration with service users, or ‘experts by experience’. Things are still fuzzy when it comes to understanding exactly how co-production influences the research process and the knowledge produced. Researchers are sometimes understandably confused about what constitutes ‘good’ co-production, how to incorporate it into a project, and what to do with the perspectives gained from peoples lived experiences. Without a research context in which experiential knowledge is valued as equal to – if not greater than – other forms of knowledge such as technical, financial or ‘scientific’, co-production runs the risk of being tokenistic or performing basic ‘reality checking’ function and the richness and value of that knowledge can be lost.
