Every organisation has operations: the people, processes, systems and assets used to create and deliver products or services. Supply chain management coordinates the external and internal network of suppliers, procurement, production, inventory, logistics, distribution and customers that supports those operations.
Effective management balances service, quality, cost, working capital, speed and risk. Optimising one measure in isolation can damage another—for example, reducing inventory without understanding lead times may increase stock-outs and lost sales.
Disruption can arise from supplier failure, transport delay, geopolitical events, natural hazards, cyber incidents, demand volatility or internal control breakdown. Resilient organisations understand critical dependencies, maintain suitable alternatives and use tested response plans rather than relying on improvised recovery.
