How effective was Albert Speer in postponing the ultimate German defeat in WWII?

i know that he was key to increase production, but obviously Germany still lost the war. How key was Speer in forestalling the Nazi defeat and counterattacking the Allies. Could the manpower and fuel shortage by the end of 1943 made his problems worse and if so to what extent?

Speer helped streamline production and workers, use as much transportation available and supplied huge numbers of equipment to the Army. Its likely without his management, the german army would simply run out of ammunition, spare parts and food in late 44 thus enabling a massive soviet or allied breakthrough
