The Challenging Phase of Concept Selection Integrated with the Customers' Judgement Noticed by the Kano Model

The paper describes how to correlate the results obtained by a customer survey performed by the Kano model and the choices made by concepts selection using scoring technique in order to identify the more promising design alternatives created by a design team. The need to correlate these results is extremely important during the design activity performed by students in a course of Product Development, because this can guarantee that the final decision is taken on the basis of a right comprehension between designers and customers. The frequency of the Kano model attributes and extent of satisfaction are put in relation with the scoring that the design team assigned to each design characteristic. Comparing these elements the design team can evaluate their choices and modify or better specify the design solution from the early stage of design. The discussion of the methodology is supported by a study case related to the design of "a pedal vehicle on which a new electronic device can be tested for the recovery of kinetic energy when braking".
