This work has the scope of turning out the validity and usefulness of a KE integrated approach to the product concept development phase and its benefits in improving the perceived â€śtotal qualityâ€ť of future product. Henceforth; we will define â€śtotal quality productâ€ť a product that satisfies both functional and emotional usersâ€™ needs; and â€śtotal quality elementsâ€ť the corresponding product attributes. The proposed approach (described in section 2) integrates the traditional methodologies used in the product concept design with KE principles and innovative statistical and quality tools such as supersaturated design; ordinal logistic regression and EVA method (briefly described in section 3). An innovative procedure to exhibit concepts in KE session is also presented. It uses the abstraction and association idea principles to elicit usersâ€™ grade of agreement for a particular kansei word. The proposed approach is fully exploited through a case study on train interior design; developed in a virtual reality environment (see section 4).
