Forty-eight subjects reiteratively designed a schedule for a set of abstract library procedures. Obtained solution schedules were measured in terms of 1 solution time, 2 satisfaction of functional design requirements, 3 stability of solution through the sequence of iterations, and 4 cluster, the degree to which solutions reflected the inherent structure of the problem. It was found that the extent to which schedules were clustered was a significant predictor of satisfaction of functional design requirements, and that the stability of solutions was a significant predictor of solution time. Weak effects of problem statement on solution variables were also identified. Author
