Supply chain resilience is no longer a competitive advantage—it is a necessity. This book explores how dual sourcing and safety stock strategies can safeguard operations against disruption while maintaining financial and operational efficiency. It examines the decision frameworks that help managers balance redundancy with agility, and flexibility with profitability. Through practical insights and cross‑industry examples, the book shows how to design supply systems that absorb shocks, protect production continuity, and support long‑term sustainability goals. Combining strategic thinking with actionable models, it guides executives in integrating resilience principles into procurement, inventory, and supplier management in an age defined by uncertainty.
