Andre is trying to determine the best way to get to his house after work, because his usual route has been blocked by emergency vehicles due to a car accident. he can't "see" a different route, so instead he imagines how he would drive to work from home if he had to take a different route. andre is using the heuristic.

Andre is using the working backward heuristic.
Working backwards, he is imagining how he would get to work from home whilst trying to determine the best way to get home from work given that his usual rout is blocked. By working backwards and imagining things from a different perspective, he may be able to find a suitable solution.
