Overview: It has been, for many years, the aim of many medical physicists in our field to ensure precision of our treatments. Delineation, treatment planning, image guidance, machine QA, plan QA all seem to aim for the highest precision achievable. Indeed, in recent years, the precision of our treatments has become excellent. However, still, a lot of effort is spent improving or maintaining this precision. Simultaneously, healthcare costs are rising, our workforce is under pressure and we can only spent our time once. Is it still worthwhile to spent resources in trying to improve the precision of our treatments, or have we reached a plateau where ‘good’ is actually ‘good enough’? Should we continue to pursue the highest precision, or is it enough to be “as precise as reasonably achievable”?
