PurposeManufacturing supply chains (SCs) across the world have become increasingly vulnerable to disruptions due to the increasing fragmentation of business functions and tasks across many firms located within the country and abroad. Despite the numerous instances of SC disruptions being reported in the literature, the study of SC vulnerability lacks adequate conceptual and empirical support. This study aims to address this research gap.Design/methodology/approachThe concept of SC vulnerability was examined considering the outcome and contextual models of vulnerability, which are well established in extant multi-disciplinary vulnerability literature. An exploratory Delphi study was then conducted to understand the extent of vulnerability of various manufacturing SCs in India, drivers of this vulnerability and the key hazards exploiting this vulnerability.FindingsThe study confirms the increasing vulnerability of manufacturing SCs in India. It also highlights the lack of top management commitment to risk mitigation as the key vulnerability driver and frequent changes in government laws and regulations as the key hazard being faced by the manufacturing SCs in India.Originality/valueThis study highlights the utility of outcome and contextual models of vulnerability as conceptual frameworks for understanding SC vulnerability. These conceptual insights along with the key manufacturing SC vulnerability drivers and hazards identified in the study should provide a basis for SC redesign for vulnerability reduction and the selection of SC risk mitigation strategies.
