Based upon the extant literature and a qualitative study of buyer-seller relationships, an exploratory model of the relationship between supply chain power, dependence, satisfaction, and loyalty is developed and presented. Four fundamental objectives are accomplished through this research and presented here. The first was to use a qualitative method to gain a deeper understanding of the logistics service driven loyalty that exists between suppliers and customers. The second was to develop a more thorough understanding of the gap in logistics service expectations between a supplier and their customers. The third objective was to examine how the power/dependence relationship affects both customer service expectations of the parties, and the actual logistics service delivered by the supplier. Finally, this research is intended to build a basis for future quantitative research of loyalty in supplier/customer relationships.
