Determining relative quality for the study of creative design output

Design creativity is often defined using the terms “novel” and “appropriate”. Measuring creativity within design outputs then relies on developing metrics for these terms that can be applied to the assessment of designs. By comparing design appropriateness to design quality, this paper develops a systematic method of assessing one element of design creativity. Three perspectives from literature are used; the areas in which quality is manifest, the categories into which quality assessment criteria fall, and how well criteria are achieved. The output of the method is a relative ranking of quality for a set of designs, with detailed understanding of the particular strengths and weaknesses of each. The process of assessment is demonstrated through a case study of twelve similar designs. Through such analysis insight into the influences on quality can be gained, which in turn may allow greater control and optimization of the qualities that design outputs display.
