| Abstract | This study investigates the impact of Quality Management Practices (QMP) on Supply Chain Management Practices (SCMP) and Firm’s Supply Performance (FSP) in the automotive industry in Thailand. To achieve this objective, the measurement instruments of SCMP, QMP and FSP were de veloped based on an extensive literature review and were verified by experts and a pilot test. For the large-scale survey data collection, multiple responses from each company were sought to improve the reliability of the information obtained. In total, 211 companies responded to the paper-based surveys or e-questionnaires . Non-respondent bias and multiple respondent bias tests were conducted to en sure similarity between respondents and non-respondents and between the single and multiple responding firms. Then, the reliability of the measures was examined with item-total correlations, Cronbach’s alpha, composite reliability and average va riance extracted. The first-order, the second-order confirmatory f actor analysis, convergent, discriminant and nomological validity were applied to confirm validity. The results show that the set of SCMP, QMP and FSP measures and their underling theories are reliable and valid for Thailand’s automotive industry. A hypothesized model was tested using path analysis of the structural equation modeling, revea ling that QMP does not only have a direct positive impact on SCMP and FSP, but it also has an indirect positive impact on FSP via SCMP. This result was valid for the whol e sample and the Thai owned companies. Furthermore, descriptive statistic validated that the automotive companies in Thailand applied QMP more extensively than SCMP . MANOVA was employed to investigate the differences across organizational char acteristics (company ownership, company size, tier in the supply chain and quality management maturity) on SCMP, QMP and FSP. Overall, there were significant differe nces across organizational characteristics on SCMP, QMP and FSP. Japanese companies, large companies, first-tier suppliers and the companies with ISO/TS 16949 had mo re intensively applied SCMP and QMP and achieved a higher level of FSP. Through multiple regression analysis, it was found that, overall, QMP significantly suppor ted every SCMP sub-construct. There was synergistic effect of simultaneous ly implemented SCMP and QMP on FSP.Moreover, SCMP had partial mediation e ffect on the relationship between QMP and FSP. In addition, in-depth case studies of two companies helped provide more information in a qualitative manner. Genera lly, the case study findings confirmed that QMP had a positive impact on SCMP and FSP and the management recommended that industry-specific quality management systems such as ISO/TS 16949 should be introduced before implementing supply chain management. However, the case companies still experienced some negative effects especially when employees were adhering too strictly to qua lity management standards or did not clearly understand and did not align their functional ob jectives to the corporate goals. |
