The iterative, trial-and-error approach of traditional user-centered approaches is argued to lead to excessive dependence on user testing and user approval, leading to overly conservative designs. By contrast, model-driven approaches based on fine-grained task models have a proven record of leading to dramatic improvements in user performance through innovative designs.
