Using Design Methods to Improve Design Quality: Verbalizers vs Visualizers

Although a wide variety of design methods are used, two questions have been little investigated: whether using many methods improves the outcome quality and who benefits more from using them. We conducted a quasi-experiment in a classroom employing a 2 (Design Method: More vs Fewer) x 2 (Style of Processing: Verbalizer vs Visualizer) between-subjects design. We obtained two findings from the data. First, the students using more design methods generated better outcomes than those using fewer design method. Secondly, verbal-oriented students generated better outcomes than visual-oriented students. Our obtained two findings will be discussed in the context of design process.
