Supply chain integration: a review of enablers, dimensions and performance

Purpose: The conceptualization of integration is built on intra- and inter-organizational relationship to manage the entire supply chain. Despite the growing number of research studies, there is a lack of consensus in current literature to define and conceptualize supply chain integration (SCI) and its drivers. The purpose of this paper is to provide comprehensive views on SCI, thereby contributing to existing literature by providing taxonomy to drivers and sources, dimensions and outcome of SCI. Design/methodology/approach: The systematic approach to literature review has been adopted to carry out this research. The study cites 154 articles, out of which 110 articles have been thoroughly reviewed, covering drivers and sources of SCI, SCI dimensions and SCI outcome. Findings: For the conceptualization of SCI dimensions, two major themes have been identified: first, internal integration, customer integration and supplier integration; second, information sharing, process coordination and strategic alliance. The authors also found that desire to improve and environmental factors prompt organizations to integrate with their partners to realize the desired outcome. Additionally, the paper identifies that integration plays a significant role in enhancing performance; nevertheless, maturity of integration may have a direct relationship with performance, and the same has been suggested as propositions for further study. Research limitations/implications: This paper has taken the systematic perspective to review existing studies and projected propositions, which is entirely based on collective views that may require empirical support. Originality/value: The paper is a unique contribution that reviews the research articles on SCI systematically. The paper also provides a distinct perspective and food for thought to practitioners, as the proposed framework may serve as a reference point to assess current SCI practices in the organizations.
