In the present turbulent market situation, building strategic information sharing (SIS) capability among the partner firms of a supply chain is imperative to create the agility and adaptability which further lead to the supply chain performance (SCP). In the available literature, combined role of agility and adaptability and their impact on SCP is poorly investigated. As a rapidly changing market environment requires the supply chains to be more responsive and flexible, supply chain agility and adaptability appear to be value-enhancing and contribute to its effectiveness. Following the resource-based views (RBV) and relational theory this study presents a model linking SIS capability, agility, and adaptability with SCP. A cross-sectional survey of 243 Indian auto component manufacturers was conducted to collect the data. The results reveal that SIS, agility, and adaptability are directly and significantly connected with SCP. This finding supports the prominently published studies. The main contribution of the study is unveiling the mediation effect of agility and adaptability on the SIS-SCP relationship. Results depict that agility and adaptability mediate the SIS-SCP relationship fully and partially respectively. The study also discusses the theoretical and managerial implications along with limitations and scope for future research.
