It is important to ask yourself this question before you begin an evaluation, and to answer it honestly. Is the evaluation intended for your own reflective use? Are you fulfilling the requirements or responding to the needs of a funder or commissioner? Are you primarily interested in evidence that will help to advocate for your work, or make your service more attractive to service users? Would you like to contribute to the wider evidence base for the arts and health sector? A clear understanding of who the evaluation is for will help you to make decisions about what to evaluate, what resources to allocate to the job, whether you might want to work with someone else to do it, and how you will disseminate your findings when you have them.
