The report, "The Business Costs of Supply-Chain Disruption," by The Economist Intelligence Unit and commissioned by GEP, examines the impacts of recent supply chain disruptions and the measures firms are taking to build resilience. The study surveyed 400 senior supply chain and procurement executives in five sectors and found that half of them work in organizations with annual revenue over US$1bn. The report supplements the results with secondary research and in-depth interviews with experts. The challenges faced by firms in building resilience are discussed, and the experts interviewed include Terrance Brick, Omera Khan, Hau Lee, David Paulson, Lutz Quietmeyer, Leigh-Ann Russell, Yossi Sheffi, and ManMohan Sodhi.
