Through the Royal Ordonnance of 7 October 1732, Vallière endeavoured to reorganize and standardize the King's artillery.

He thus developed the de Vallière system,A Dictionary of Military History and the Art of War By André Corvisier, p.837 which set the standard for French artillery until the advent of the Gribeauval system.
