Various methods are offered to measure design creativity. Nonetheless, a debate continues over the development of a trustworthy and objective method to mitigate the influences on the evaluation. Therefore, we propose and develop a novel tool and approach for evaluating design creativity, which reframes creativity evaluation as a structured and data-driven process. This tool represents a significant advancement in the evaluation of design creativity by mitigating objective factors. Importantly, our tool enables researchers and educators to adopt it freely and objectively for evaluation.
