The bullwhip effect can be explained as an occurrence detected by the supply chain where orders sent to the manufacturer and supplier create larger variance then the sales to the end customer. These irregular orders in the lower part of the supply chain develop to be more distinct higher up in the supply chain.

The bullwhip effect just like “Butterfly effect.” The manager should doing the environment scanning, noticed any tiny changes. To prevent the huge lost which is because the customer’s demand changes.

The wholesaler also will do the same thing; increase their order to the producer.
But their information’s transfer is slower than the demand change. Each time they send the massage need take for a long time. Their lead time is too long that cause their problem.
