An empirical investigation into supply chain vulnerability

A growing number of academicians and practitioners have put supply chain risks on their agendas, particularly triggered by a recent series of catastrophic events that have disrupted economies and supply chains around the globe. Given the increasing awareness of this important topic, the purpose of this research was to study supply chain risks in more detail and to investigate the relationship between supply chain vulnerability and supply chain risk. Responses from 760 executives from firms operating in Germany reveal that supply chain characteristics such as a firm’s dependence on certain customers and suppliers, the degree of single sourcing, or reliance on global supply sources are relevant for a firm’s exposure to supply chain risk. Overall, this research represents the first large-scale investigation of this important relationship and provides a finer understanding of the antecedents of supply chain vulnerability. r 2007 Elsevier Ltd.
