A supply chain is the entire journey a product takes — from raw materials to the final customer. It includes every step: sourcing, manufacturing, packaging, shipping, and delivery. Most customers never think about it, but supply chain management is one of the most critical operations for any business.
Here is a simple example: the iPhone you buy at a local store was designed in California, its chips came from Taiwan, the screen from South Korea, assembled in China, and shipped across the world to your neighborhood outlet. That entire network of suppliers, factories, and logistics providers is the supply chain.
A well-managed supply chain keeps costs low, ensures products are available on time, and keeps customers happy. When it breaks down — like during the COVID-19 pandemic — you get shortages, price spikes, and long delivery delays.
