Abstract: To deal with urgent requirements of effective quality data management in the product design phase, a product quality data management model based on quality characteristics was proposed. According to product design process, quality characteristics and data were defined. After analyzing quality assurance process, multidimension of quality characteristics and its evolution properties, mapping view between quality data and product quality properties was provided. The hierarchical structure, characteristics and management requirements of design quality data were analyzed. A management model of design quality data was proposed, which was quality -properties-based and was able to satisfy the specifications of product quality management and process management. The software prototype QQ-Dplatform was developed and a case study of design quality data management of a mechanical product using this model was presented, which has proved its feasibility and effectiveness.

Key words: product design, quality assurance, quality characteristics, design quality data, quality data management model
