The findings of this study have determined that the relationship between product quality and customer loyalty is significant in Malaysian E&E manufacturing industry. In addition, the relationship between product quality and customer loyalty was partially mediated by commitment. Product quality is an essential aspect of product differentiation, which is important for suppliers in Malaysian E&E manufacturing industry to develop customer loyalty. In Malaysian E&E manufacturing industry, suppliers can develop customer loyalty with the direct influence of product quality. In additional, suppliers can develop customer loyalty indirectly by putting efforts on product quality to gain commitment, which subsequently influences customer loyalty. In Malaysian E&E manufacturing industry, relational elements do not influence customer loyalty the same ways. The relationship between cooperation and customer loyalty was significant, but the relationships between trust and customer loyalty, and communication and customer loyalty were not significant. The relationships between all three relational elements and customer loyalty became significant when the mediating effects of commitment were present. The relationship between cooperation and customer loyalty was partially mediated by commitment, and the relationships between trust and customer loyalty, and communication and customer loyalty were fully mediated by commitment. As such, trust and communication do not develop customer loyalty directly in Malaysian E&E manufacturing industry. It is important for suppliers to focus on gaining customer commitment, because of its significant influence on customer loyalty. In contrast, cooperation can develop customer loyalty directly, as well as indirectly with the partial mediating effect of commitment. In summary, trust, cooperation, and communication are significant relational elements of relationship marketing, in which trust and communication develop customer loyalty differently from cooperation in Malaysian E&E manufacturing industry.
