One consequence of poor coordination within a supply network is amplification of changes in demand upstream. Amplification of demand changes has been called the bullwhip effect. For example, a retailer may order only full truck loads from its suppliers. Instead of understanding the actual end-customer demand, the suppliers see huge swings in orders that are due essentially to the retailer's desire to minimize transport costs. This has the unfortunate impact of increasing manufacturing costs at the suppliers, because they are asked to make large quantities at irregular time intervals. write a summary about the bullwhip effect the length is maximum 3 pages
