The main objective of this study is to evaluate the role of supply chain integration on the supply chain performance of the business sectors. The reviewer has used many studies specifically conducted on the effect of supply chain integration dimensions; internal integration, supplier integration and customer integration on which many studies are currently emphasized on. The published articles related to this topic have been searched and the best 12 were chosen on which deeper review has been made. Finally, it has been reached that internal integration; supplier integration and customer integration have all significant and positive effect on the performance of business sectors’ supply chain. Limitations have been found in that the varying studies made have found somehow deviating findings in terms of the effect of the supply chain integration dimensions on the performance of business supply chain and the reviewer has recommended that such studies on the concept need to be extensively made and even the dimensions touched by the existing studies need to incorporate the important dimensions.
