Translate the following English sentence to French:
"However, we do have to introduce something different: we have to find a way of assessing our progress and providing public opinion with tangible facts, and we therefore have to use a benchmarking system. By the term benchmarking, which was relatively unknown up until a few years ago, I mean a completely institutional means of comparing and assessing our progress."
Nous devons, néanmoins, apporter un élément nouveau : nous devons trouver la manière de mesurer ces progrès, nous montrer concrets devant l'opinion publique et utiliser le benchmarking - un mot presque inconnu il y a encore quelques années - ou, en termes plus simples, la comparaison et la mesure des progrès réalisés d'une manière absolument homogène.
