Resumen: The modular design harbors a potential development in the prosumer scope that has hardly been previously exploited. Their joint application can lead to products focused on user participation through modular design. This work proposes and validates a concept evaluation metric in the design phases that meet these characteristics. To do this, 24 external designers and prosumers evaluate five products using this method. The results and conclusions contribute to the improvement of the method and provide information on how to approach it to the prosumers.
