Interplant coordination, supply chain integration, and operational performance of a plant in a manufacturing network: a mediation analysis

Purpose The purpose of this paper is to investigate the relationships at the level of plant in a manufacturing network, labelled as networked plant in the paper, between inter-plant coordination and operational performance, supply chain integration (SCI) and operational performance and inter-plant coordination and SCI. Design/methodology/approach This paper is developed based on the data obtained from the sixth version of International Manufacturing Strategy Survey (IMSS VI). Specifically, this paper uses a subset of the IMSS VI data set from the 606 plants that identified themselves as one of the plants in a manufacturing network. Findings This paper finds that external integration is significantly related to operational performance of networked plant, whereas internal integration is not. As an enabler for external integration, the influence of internal integration on operational performance of networked plant is mediated by external integration. This paper also provides evidence to the purported positive impact of internal integration on inter-plant coordination, as well as the positive impact of inter-plant coordination on external integration. It further suggests that inter-plant coordination can influence operational performance of networked plant through external integration and also mediate the relationship from internal integration to performance through external integration. Originality/value This paper contributes to the SCI literature and extends the understanding of the impact of SCI on the operational performance by selecting networked plant as a unit of analysis. Besides, this paper distinguishes inter-plant coordination from SCI and investigates the relationship between inter-plant coordination, SCI, and operational performance for the first time.
