Was It the Schliffen Plan That Led to the Prolonged War?

The germans did expect that they would have a quick war if they implemented the schliffen plan. And what happened are, at least most of the accounts that i read, that they didn't actually implement the schliffs plan as it was intended to be implemented. So he made the decision to simply go straight down from the north. That made it so that the french had a very short front to defend. Then they were able to do it and dug in and did do it. Was part of what led to the prolonged war, is what i am trying to suggest.
