Abstract

This is the first research to empirically study the congruity in supply chain operations strategies. The tests show that the congruity in supply chain operations strategies are related to performance and also moderate the association between performance and the types of supply chain relationships. 308 manufacturing firms were studied for empirical tests. Various methods including multiple regressions, cluster analyses, and logistic regressions are applied in this study. Based on the tests, five hypotheses are supported and only one hypothesis is inconclusive. This dissertation contributes in different thresholds. First, by studying operations strategies through a different angle (the supply chain instead of a firm) this study reconciles results in the relationships between performance and operations strategies and between performance and supply chain relationships. Therefore, this study contributes to reconciling two long-term puzzles in both operations strategies and supply chain management literatures. Second, this research draws on three different disciplines, operations strategies, supply chain management and organization theory (resource dependence theory). This interdisciplinary approach provides a broader perspective in operations management research. Third, through this research, guidelines are provided for not only powerful firms but also the weak ones on how to improve their performance through developing different types of supply chain relationships and integrating their operations strategies with their supply chain members.
