Well yes. The planning of the Germans in WW I was according to the Schlieffen-Plan to beat the French on the Western front fast to then direct all troops against Russia. The Germans thought that Russia would need more time to fully mobilize its armies. They thought that Russia was harder to beat than France, obviously because of Russia's manpower. What Germany always feared was to have to fight a two-frontiers war in the West and in the East simultaneously That plan did not work out.
Russia mobilized its troops faster than „planned“ by the German High Command and began to invade Eastern German territory. It then became a reversed Schlieffen-Plan: first beat the Russians, then direct all troops to the West. This became possible when Germany made a seperate peace with Russia at Bresk-Litowsk, today Poland. But the troops then sent to the West to beat the Alllies in the West were not enough, even more so when the US entered the war in the West and sent fresh troops.
In WW II, you could say the Germans followed the same plan and did better.
They occupied all of Western Europe and tossed out the Brits from the Continent. So all according to the Schlieffen-Plan. Then they directed all their attention towards the East to beat the Soviet Union which was a bit over-optimistic. Smart minds in Germany at that time already knew that is would be impossible to beat the Soviet Union for Germany, just compare the sheer numbers between Germany and the Soviet Union.
