© 2012 Product Development & Management Association. As traditional sources of competitive advantage shrink, firms seek new ones. One such source of competitive advantage is product design because of its effects on customer experience. To understand the role and impact of product design on customer experience, we propose an integrated, customer-based framework for product design that we call the total product design concept (TPDC). We define a product's TPDC as consisting of three elements, namely functionality, aesthetics, and meaning, each of which arises from more elemental product characteristics. We elaborate on the structure of a product's TPDC, its three elements, and the links between those elements and customers' experience with a product. We provide an illustrative application of the TPDC using data from the U.S. auto market. The findings from that application support the proposed three-dimensional view of the TPDC, and demonstrate heterogeneity both in the TPDC's structure and its effects on customer satisfaction. For all three segments, functionality enhances customer satisfaction. For the largest segment of customers, functionality is the most important factor, followed by aesthetics. For the other two segments, customer satisfaction is most influenced by the meaning element of TPDC. We discuss the implications of these findings for the auto industry in particular, and the potential use of the TPDC more generally.
