This manuscript targets on setting forth as well as developing an impeccable paradigm for procuring the influences of technologically vigilant leadership (TVL) as a potentially facilitator of Industry 6.0 implementation (IRI) to reach the highest performance of smart sustainable circular supply chain management (SSCSCM). From a methodological standpoint, this model has been established conceptually and substantiated by structural equation modeling instrument rested on the consideration of a cross-sectional sample of 483 valid informants retrieved from a well-structured questionnaire survey strategy in small and medium enterprises (SMEs). The outputs demonstrated the existence of strong interconnections between the two constructs of hypothesized model. More concretely, TVL was corroborated to be the greatest contribution to IRI. Additionally, the IRI was authenticated statistically to be the triggering component for amelioration and enhancement of SSCSCM. Apart from the theorical contribution to the movement of research trends targeted at Industry 6.0, this research was valuable to deepening the knowledge and understanding of SMEs as they strived to realize SSCSCM through TVL and IRI, most notably, these in-depth insights would offer guidelines for policymakers in formulating better TVL mechanism to harness the benefits of IRI and therefore intensify SSCSCM.
