Design space exploration in parametric systems

Abstract

In this paper, the effects of design-task specificity level on design space exploration are studied. An experiment was conducted to study the effects of goals and methods on design process and design solutions by 16 individual designers, who performed two design tasks under different combination of design goal and method specifications. Protocol analysis and outcome-based analysis were carried out. The results of the outcome-based analysis reveal that the quality of the design solutions can greatly be affected by goal specificity level of a design task, whereas in case of quantity, novelty and designer's self satisfaction level, the effects are insignificant. None of these metrics showed significant influence of method specificity levels of a design task. The process-based analysis on the other hand, reveals some interesting search behaviors in parametric systems, which are then used to explain the possible reasons for insignificance in quantitative data.
