If it is someone who is in over their head trying to meet a goal or deadline, then probably try to back them off before they burn out, and go back to the planning stage and come up with something that has a chance for success. If it is a noob-syndrome type then the best thing is to get them into an environment where they can learn quickly what the ante is for a "real" solution -- so high quality test data and mentorship are ideal.
