Design problem-solving: Understanding the significance of iterative-behaviour in design

Different concepts and definitions associate iterative-behaviour with repetition. This study consider iterative-behaviour simply means as the act that involve repetition of activities to improve the evolving design. The research further investigate the significance of designer iterative behaviour in design using sketching as the media for design interaction. The retrospective protocol analysis of the video data have identified and measure designer iterative behaviour in design, through a sketching and scoring sessions by five (5) final year undergraduate students and five (5) design tutors, all from the Department of Architecture, University of Technology Malaysia. The design and score were qualitatively and quantitatively compared using close group discussion and the Pearson correlation coefficient analysis. The result shows that in design problemsolving, designer iterative-behaviours were not statistically significant in determining the quality of design.
