I think that you may be a little too defensive Rob; concerning the promotion of the Medical Engineering Course you are involved with. However it does appear to be a very worthwhile and well designed course presented by experienced Med Engs (possibly including some "old Toms"). Alas I believe, together with his future employer, that Den is adequately qualified for the role he has been selected for. No doubt he would also benefit from your course if he chooses to study it and in an ideal world all would benefit from vocational training devoted to each engineering specialism, but capable and experienced staff can also quickly adapt to new challenges without the luxury of completing such training.
