Building a resilient enterprise involves changing how a company operates to reduce vulnerability and increase competitiveness. This can be achieved by either creating redundancy or increasing flexibility in the supply chain. Redundancy involves keeping extra resources in reserve, while flexibility means building in organic capabilities to quickly sense and respond to threats. Research shows that companies like Land Rover, Toyota's supplier Aisin Seiki Co., UPS, Dell, Baxter International, DHL, and Nokia have successfully built flexibility into their supply chain elements, giving them a competitive edge in the marketplace.
