We will diagnose before we prescribe. As professionals, we will always begin at the beginning. As with doctors whose clients turn up asking for a prescription having googled their symptoms and self diagnosed, we will use our professional approach to take them back a step and apply our expertise to a proper diagnosis. Doctors do MRI scans, blood tests and so on before prescribing, accountants do audits, and so on. It is the way of the professional to investigate, and consider, before acting.
