Abstract
Innovation is understood to be closely related to the competitiveness and economic success of an industry. Nonetheless, in the engineering community, it is not yet fully accepted that creativity represents a key element of success. Defining creativity and understanding the functioning of its different aspects can make the early stages of product development more fruitful in terms of innovation. One way of understanding the impact of creativity is by measuring it. The evaluation or quantification of creativity allows us to investigate its complex aspects. Furthermore, measuring creativity facilitates the evaluation of the practices used by designers in different stages of product development. Therefore, being able to effectively measure creativity can lead to substantial improvements in product development processes. In this work, we investigate two different creativity metrics, namely, originality and novelty. The main objective is to analyse the effect of different ideation stages on the final creative outcome using these metrics. The experiments are conducted using a dataset containing creativity scores of two different stages of a concept design. The results of this analysis show that focusing only on a few concepts after creating many in the first stage, significantly improves the originality of the concepts. The results also show that despite a correlation between novelty and originality, the novelty metric was more difficult to interpret. We also identified a set of features that resulted in more creative concepts.
