What does Supply Chain mean?
The supply chain is the journey that a product takes before it reaches your store. For example, a product's supply chain could be:
Raw ingredients are farmed / harvested > raw ingredients sold to a wholesaler > raw ingredients bought by component manufacturer and taken to their premises where they are processed and manufactured > components sold to product manufacturer where they are assembled into the final product > product is sold to a distributor and stored in their warehouse > product is bought by retailer (you!).
