The paper concerns to the concept of product's total quality, its determinants, and the dimensions wich constitute this quality. We admit that product quality should be evaluated via consumer's total satisfaction. Product quality for consumers includes at least the following dimensions: the product quality per se; the performance of product quality over time; the quality of services related to the use of the product; and the product lifecycle costs. This study seeks to specify and to discuss each of these quality dimensions related to consumer's satisfaction.
