"chargé de mission".Thank you
I got it - PROJECT MANAGER!!!
The best thing I've found for the moment is "responsable for / in charge of". I will let you know if i get a better idea!
How to say "le bon de roulement (au long de la livraison)", please.
"Smooth progress"? It's so strange.
Project manager is great for something domestic, but the word is often used untranslated from the French.
