The supply chain consists of the physical and communication paths connecting multiple, interrelated businesses. Material, goods, products and information flow through these paths from their points of origin or source (often viewed as beginning with raw material) to the final end consumer. This flow is sometimes extended to include the eventual disposal, recycling or return of goods. See also, Supply Chain Management, Logistics , Material Handling, and Third Party Logistics. Note that all of referenced terms are highly interrelated and their definitions are frequently intermingled.
