Global supply chains are built for speed and efficiency, but one shock can bring the entire system to a halt.When Supply Chains Collapse: Lessons from 20 Global Disruptions takes readers inside the crises that exposed the hidden weaknesses of global trade, from earthquakes, cyberattacks, and factory shutdowns to wars, shipping blockages, resource shortages, and geopolitical conflict. Through twenty compelling real-world cases, the book reveals how small failures become global emergencies, why efficient systems often lack resilience, and what organizations can do before the next disruption strikes. More than a history of supply chain disasters, this is a practical guide to identifying single-source dependencies, closing visibility gaps, measuring risk, strengthening supplier networks, and stress-testing critical operations. Written for business leaders, professionals, policymakers, and students, this book delivers one urgent message: disruption is inevitable, but collapse is not.
