The purpose of this research is to find a need-definition method to improve the product concept quality. In this experiment, six teams conducted a design process comprised of “user research”, “definition of needs” and “creation of product concept” under the same theme. Within the definition of needs, three teams (type A) filled in “needs definition form”, while the other three teams (type B) filled in a “deep needs finding sheet” in addition to the “needs definition form”. An evaluation for the created product concepts was done by six experts, yet no correlation was found between the evaluation’s results and these methods. Nevertheless, an evaluation of the process has revealed differences in the quality of the discussion. A qualitative analysis using the Grounded Theory Approach and a linguistic analysis using text-mining were conducted on the discussion of each team. Type A teams discussed thoroughly the idea for the product’s function solving the problem they found at the beginning of the process, yet they did not discuss the user’s needs as a background for their idea. Type B teams acknowledged the possibility of many problems and talked adequately about the user’s needs, yet only few remarks regarding a specific idea were made. The evaluation of the product concept was not affected by changing the needs definition format; nevertheless the quality of discussion was improved by the use of “deep needs finding sheet”. The results reveal the basic principles of needs-definition process that lead to high quality design concepts.
