“Without a good model we operate by rote, blindly; we do operations as we were told to do them; we can’t full appreciate why, what effects to expect, or what to do if things go wrong. As long as things work properly, we can manage. When things go wrong, however, or when we come upon a novel situation, then we need a deeper understanding, a good model.” (Norman 13)
