Lots of works have been conducted to explore and explain inter-organizational relations between supply chain partners. However, we have noticed that there is no accurate agreement between authors. Thus, to better understand this disparity, we studied supply chain inter-organizational relationship dynamics in eight (8) different industries to bring out an analytical framework that allows a better understanding of such an issue. These casestudies instruct professionals and researchers so that they bring up their level of abstraction that remains appropriate to catch this dynamics in order to guide decision making and future research and studies.
