Two studies of design problem solving are reported. Experiment 1 presents an observational study of an actual client-designer work session. Analysis of the session transcript reveals a systematically structured interaction. The client and the designer decompose the overall design problem into sub-problems, each of which is smaller and somewhat more well-structured than the overall problem. Experiment 2 is a laboratory study. The client role is simulated by an instruction booklet subjects play the designer role. Again, it is found that subjects spontaneously structure the elements of a design problem into sub-problems the nature of which is systematically related to aspects of problem structure. There is high intersubject agreement as to how the decomposition into sub-problems should proceed. Author
