Isn't that due to a lack of leadership, rather than a problem with teamwork itself? Somebody has to be ultimately in charge and willing to put a stop to endless debate.
It is more like a "design by committee" issue to me. The decisional structure needs to be built for some opinionated decision. When you have a committee there is not one clear thing they are solving for as everyone has an agenda to tug the language towards their own interests. The result of that can certainly be inaction because it is easier to say no than yes.
