A supply chain is a network of individuals and companies who are involved in a creating a product and delivering it to the customer.
It begins with the sourcing of raw materials, whether that means curing leather, manufacturing sheet metal, or mining diamonds.
From there, the raw materials are hauled to a wholesaler, who will sell them in batches to manufacturers.
Once they are delivers, the manufacturer uses the materials to create a product, which is then delivered to the retailer.
Every day, millions of sailors, truck drivers, longshoremen, warehouse workers and delivery drivers keep mountains of goods moving into stores and homes to meet consumers’ increasing expectations of convenience. But this complex movement of goods underpinning the global economy is far more vulnerable than many imagined.
