The Design of Everyday Things.
Norman, a cognitive psychologist, outlines the elements of effective user-centered design, which include making the inner workings of devices visible, exploiting natural function, controlling relationships, and using constraints successfully. Through both fable and anecdote, Norman illustrates forcing functions and how bad design can exacerbate the consequences of human error. This classic text is a valuable introduction to the role of design in patient safety.
