Supply Chain Management - Introduction.
In a supply chain, virtually all of the members serve as
both customers as well as suppliers. In the Li & Fung
example, the Korean yarn producer and the Japanese
zipper producer are probably only suppliers and the
customer’s customers (folks like you and me) are
probably only customers. Every other organization in the
supply chain is both a customer and a supplier. See the
figure on slide five (green - supplier, yellow - customer,
orange - both).
