This paper presents an empirical investigation to study the role of quality in supply chain management in development of brand equity. The study uses two questionnaires, one for measuring quality in supply chain adopted from Fynes et al. (2014) [Fynes, B., De Burca, S., & Marshall, D. (2004). Environmental uncertainty, supply chain relationship quality and performance. Journal of Purchasing and Supply Management, 10(4), 179-190.] and the other for measuring the brand equity, which was adopted from Buil et al. (2013) [Buil, I., De Chernatony, L., & Martínez, E. (2013). Examining the role of advertising and sales promotions in brand equity creation. Journal of Business Research, 66(1), 115-122.]. The survey has accomplished among auto part producers in Iran. The study selects 385 randomly selected people who were active in this industry. Using Spearman correlation ratio as well as Stepwise regression techniques, the study has concluded that there were positive and meaningful relationships between three supply chain factors, namely relationship, commitment and compatibility, and brand equity.
