Retailers very often see smooth demand with minor fluctuations as shown on the figure below.
However, as soon as there is a chance for negotiation, the results of simulation become much better Analyses of recent papers shows that researchers do not argue about the causes and consequences of bullwhip effect, but try to find remedies for negative impact on the supply chain performance. For instance, consumption of diapers by babies – is constant; consumption of bread, salt, ketchup and other food – constant, etc.The order that the manufacturer receives is often much larger than what the actual customer's demand is, at the point of sale.This irregularity or variance in the size of the orders placed, increases as we move up the supply chain, i.e.It leads to excessive safety stock, higher production costs and overheads, potential final product quality distortions, poor customer service, lost sales, higher logistics costs, and so on.Some of researchers try to find origins of the bullwhip effect in the psychology of decision makers.In a supply chain for a typical consumer product, even when consumer sales do not seem to vary much, there is pronounced variability in retailers' orders to wholesalers.
Orders to the manufacturer and to the manufacturer's supplier spike even more.
This helps in scheduling production, planning material requirement, control of the inventory and planning capacity. Also, the lead time of the orders varies or fluctuates drastically in some cases, which might force the buyer to place bigger orders.

Forrester had never named it neither Forrester, nor bullwhip effect).
The term "Forrester effect" used to denote what is now called demand signal processing, as Forrester was the first to demonstrate this phenomenon through dynamo simulation.
To solve the problem of distorted information, companies need to first understand what creates the bullwhip effect so they can counteract it.1.
