The study aims to develop a model for the survivability of sustainable supply chains of small and medium enterprises (SMEs) during the Covid-19 pandemic. With the help of exhaustive literature review, constructs and items are identified to collect the responses from SMEs. A total of 278 complete responses are received and six hypotheses are developed. Major constructs identified for the study are supply chain performance measurement under uncertainty (SPMU), supply chain cooperation (SCCO), supply chain positioning (SCP), supply chain administration (SCA) and supply chain feasibility (SCF). Findings of the study will help SMEs in developing strategies to improve survivability during uncertain business environments.
