This document discusses customer requirements in the supply logistics chain. It defines a customer as not only the person or organization that pays the invoice, but also users of products and services. An organization can determine customer requirements through demand creation processes like marketing to understand what customers want and attract them. It is important to identify customer requirements to match existing products and services to customer needs and expectations, and to understand requirements before committing to supply anything. A diagram shows the actors in the logistics chain including providers, manufacturers, carriers, retailers, and customers.
