Supply chain risk refers to the potential for disruptions to impact a supply chain, while resilience is a supply chain's ability to prepare for, adapt to, and recover from these risks. Effective risk management identifies potential issues like geopolitical tensions or natural disasters, whereas resilience focuses on building an agile and adaptable system that can minimize the impact of disruptions, even if risk can't be eliminated. Building resilience involves strategies like improving visibility, collaborating with suppliers, and diversifying sourcing, supported by technologies like AI and blockchain.
