Reducing the Subjectivity in Creativity Assessment

Previous research presented a method, called the Comparative Creativity Assessment (CCA) that calculates the creativity of individual concepts in a set of designs. Several limitations regarding these metrics are addressed and mitigated within this paper with the creation of the Expanded Creativity Assessment Method (ECAM), namely how to reduce the subjectivity of the function weights and factor in combination effects between two or more functions. The subjectivity limitation is mitigated by the inclusion of the combination effects through a major expansion to the original metrics with data validation based on analyses of the original concept data (using the former method of setting the function weights) versus using the expanded method. Statistical analysis of the different methods to calculate creativity is discussed in the Results and Conclusions.
