This results in an excess of inventory in the supply chain. Price variations — special discounts and other cost changes can upset regular buying patterns; buyers want to take advantage on discounts offered during a short time period, this can cause uneven production and distorted demand information.
Possibilities to minimize the bullwhip effect in order to avoid costs: These irregular orders in the lower part of the supply chain develop to be more distinct higher up in the supply chain. The ripple effect of small changes in customer demand are magnified upstream through a supply chain all the way from the customer to the retailer to distributor to manufacturer.
This method is developed and Example of bullwhipp effect mainly in the German automotive industry, with its expanded supply chains  and is established in several EDI-formats between OEMs and their suppliers.
Target stock levels, safety stocks and demand forecasts are updated in view of information or deviations from targets. The 5 major reasons Example of bullwhipp effect to the bullwhip effect according to Lee: Barriers to the implementation of a demand-driven supply chain include the necessary investment in information technology and the creation of a corporate culture of flexibility and focus on customer demand.
Economies of scale in ordering, production set-ups or transportation will quite clearly increase order variability. Shawn Grimsley Failure to manage a supply chain effectively can lead to inefficiencies.

This variance can interrupt the smoothness of the supply chain process as each link in the supply chain will over or underestimate the product demand resulting in exaggerated fluctuations.
This is consistent with findings of supply chain experts who have recognized that the bullwhip effect is a problem in forecast-driven supply chains, and careful management of the effect is an important goal for supply chain managers.
The lead-time is a key parameter to calculate safety stocks. Optimize your inventory allocation process based upon an understanding of your demand certainty. The third bullwhip creator is the practice of order batching.

In the s, Hau Lee. The Bullwhip Effect (or the Forrester Effect) is defined as the demand distortion that travels upstream in the supply chain due to the variance of orders which may be larger than that of sales, or the presence of too many echelons in the supply chain (Lee and Billington, ).
P&G called this phenomenon the “bullwhip” effect. (In some industries, it is known as the “whiplash” or the “whipsaw” effect.) When Hewlett-Packard (HP) executives examined the sales of one of its printers at a major reseller, they found that there were, as expected, some fluctuations over time.
