What is the panel's preferred scoring matrix? We've used 0-3, 0-4, 0-5, now currently using 0-10.
We do not have a particular view, and different procurements will suit different matrices on a case-by-case basis (depending on the requirement). The important element is that the matrix – however drafted – sufficiently delineates between each of the scores used (and that this is transparently disclosed so all tenderers can understand it).
