In the research work previously submitted for potential publication it was pointed out that trust, commitment, conflict handling and two-way communication positively influence customer loyalty at the four major banks and Capitec Bank in South Africa. Given the findings of the two previous articles, the purpose of this third article is to establish a conceptual framework that will provide banks with more guidelines to build customer loyalty. The methodological approach is based on the population from the previous two articles, which included all retail customers banking with the four major banks and Capitec Bank in South Africa. The statistical analysis that was used in the previous two studies included descriptive statistics and multiple regression analysis to test the hypotheses. It became evident from the hierarchical multiple regression analysis that the four variables investigated in the original field study do not equally influence the customer loyalty of banks. Commitment has the largest influence on customer loyalty, followed by two-way communication, conflict handling and trust. The banking industry in South Africa, however, would need to be careful in allocating their time and resources to these variables in a similar order of priority, as there are also other factors that must be taken into consideration and that will influence the focus of the bank’s customer loyalty plan. Consequently, the framework proposed for this article provides more guidance on the strategic importance of each variable, as well as guidelines that can be implemented to increase the customer’s level of commitment, two-way communication and trust and resolve conflict effectively.
