Methods for Identifying and Controlling Weak Links in the Supplier's Product Guarantee Capability

Abstract

Under the background of the transformation of quality management mode, in order to build a unified system framework of product assurance capability of suppliers at all levels, a method to identify the weak links of product assurance capability of suppliers is proposed. Firstly, the evaluation index system of product assurance capability is constructed from the perspective of the whole process and all elements, and the corresponding quantitative analysis method is given. In order to improve the scientificity of the analysis process, the characteristics of maturity level are refined, and the quantitative method of expert opinion weight coefficient based on compatibility analysis is proposed, which breaks through the limitation of traditional expert weight. Finally, aiming at defect recognition, a method of drawing risk radar map is proposed based on risk perspective. The example shows that the method proposed in this paper can effectively analyze the defects of supplier's engineering capability, and provide a strong basis for its continuous process improvement.
