Supplier risk management (SRM) is an evolving discipline in operations management for manufacturers, retailers, financial services companies and government agencies where an organization is dependent on suppliers to achieve business objectives. The complexity and globally outsourced nature of modern supply chains, combined with the practice of optimization techniques such as lean and just-in-time manufacturing in order to improve efficiency, has increased supply chain vulnerabilities to even minor supply disruptions. While these models have allowed companies to reduce overall costs and expand quickly into new markets, they also expose the company to the risk of a supplier bankruptcy, closing operations, data breach or being acquired. Among the several types of supply disruptions, most severe are those that have a relatively low probability of occurrence with a very high severity of impact when they do occur. While such risks cannot be eliminated, however, its severity can be reduced. (en)
