Applications of codesign and related participatory approaches endeavour to democratise the process and product of health service research and improvement efforts. As a group of methods that are ground in a user-centric, participatory approach, codesign is valued for supporting people with lived experiences of a health condition or service to have their voices heard and acted upon via their contributions to codesign activities. 1,2 It is now well-established that the practice of codesign is fraught with challenges in ensuring equity, access to and inclusion in its processes to realise its proposed gains. [1][2][3][4] Those who facilitate codesign activities, by planning, guiding and supporting the codesign process, are central actors who, through their practice, seek to achieve a democratic, effective and inclusive process.Yet codesign facilitators are a heterogenous group of individuals who may occupy a variety of additional roles relevant to the codesign goals beyond that of facilitating the process. Facilitators' background, personal characteristics, motivations or other attributes may influence the group dynamic and ultimately outcome.
