Suppose after a tiring day at the office you return home to find your two children engaged in a squabble in the living room over the last remaining chocolate bar. The solution is obvious – cut it in half. However, if you were a facilitative mediator you might ask each of the children why they wanted it. You might also find that child#1 says they want a snack, but child#2 says they want the wrapper because it contains details of a competition they want to enter. That would lead to a different solution with a better outcome for both.
