In a general industrial condition, there will be a manufacturer, supplier, distributor, retailer, wholesaler, and consumer. This consumer can also be an internal consumer in the same organization. For instance, a fabrication store fabricates many types of raw steel into various building elements in general machining, cutting, welding centers, and then assembles to order for shipment to the customer. Flow in this plant is from an assembly/process section to another with a relationship as a supplier and customer (internal). The acquisition takes place at every phase from the previous phase along with the whole flow in this supply chain.
