ABSTRACT
The 5 Whys is a probing technique used to explore the cause-and-effect relationships underlying a particular problem. Product flow includes movement of goods from supplier to consumer, as well as dealing with customer service needs such as input materials or consumables or services like housekeeping. Flow in such a company is from one process department to the other, in a supplier-consumer internal relationship. Acquisition is taking place at each stage from the previous stage along the entire flow in the supply chain. In any organization, the supply chain has both accounts payable and accounts receivable activities and includes payment schedules, credit, and additional financial arrangements. A supply chain has a series of value-creating processes which extend over the entire chain in order to provide added value to the end consumer. Risks in supply chain are due to various uncertain elements covered under demand, supply, price and lead time.
