Quality management practices and their relationship to buyer’s supplier ratings: a study in the Korean automotive industry
研究韩国汽车行业一级供应商的质量管理实践，发现整体评级高的供应商更注重过程管理和员工满意度，但按合格质量分类时无显著差异。
Abstract This research explores if quality management practices are different among suppliers whose performance is rated high, medium, or low by a common buying company and identifies which specific practices contribute to the differences. The entire population of first‐tier suppliers to a Korean auto assembler was surveyed to measure use of quality management practices. Useable returns were received from 25% of the suppliers surveyed. To measure conformance quality and overall rating, suppliers were categorized into high, medium, and low performing groups based on the buying company’s data. Multivariate analysis of variance was done using general linear model (GLM‐MANOVA) to explore differences in the high‐, medium‐, and low‐performing supplier groups based on their use of quality management practices. No statistically significant differences were found when suppliers were categorized based on conformance quality. However, when categorized based on overall rating, the highest rated suppliers were found to emphasize process management and employee satisfaction to a greater degree than the lowest rated suppliers.
