What is Supply Chain Management?
Supply chain management (SCM) encompasses the planning, execution, and optimization of all activities involved in sourcing, procurement, manufacturing, and delivery of products from raw materials to end consumers. It coordinates flows of materials, information, and finances across the entire network of suppliers, factories, and distribution centers.
Effective SCM balances three competing objectives: cost efficiency (minimizing total supply chain costs), responsiveness (meeting customer demand quickly), and resilience (maintaining operations during disruptions). The optimal balance depends on the product and market—fashion products require responsiveness, commodity products require cost efficiency, and critical components require resilience.
Modern supply chain management leverages technology extensively: demand forecasting using AI/ML, real-time inventory visibility through IoT sensors, blockchain for traceability, and digital twins for simulation and optimization. The COVID-19 pandemic exposed vulnerabilities in global supply chains and accelerated investment in diversification and nearshoring.
In case interviews, supply chain questions often involve optimizing distribution networks, reducing inventory costs, improving delivery times, or managing supplier risk. Key metrics include total cost to serve, order fulfillment rate, inventory days on hand, and on-time delivery percentage. Strong candidates consider trade-offs between efficiency and resilience.
Real-world example
Toyota's supply chain management approach emphasizes long-term supplier partnerships, just-in-time delivery, and continuous improvement. However, the 2011 Fukushima earthquake revealed concentration risks, prompting Toyota to diversify its supplier base across multiple regions.
