translate English to French: It was not sufficient to claim that management improvement measures were effective or efficient: the results of change had to be demonstrated by comparing the situation before and after specific projects were carried out.
Il ne suffisait pas d'affirmer que les mesures d'amélioration de la gestion étaient économiques ou efficaces : encore fallait-il faire la preuve des changements obtenus, en comparant la situation avant et après la mise en oeuvre de tel ou tel projet.
