The Bullwhip Effect

What is The Bullwhip Effect?

The bullwhip effect describes an instance wherein tiny variations of the demand on the end that is retail of the distribution chain are amplified as you move upwards in to the manufacturing end of the chain. end of the retail chain up to manufacturing.

This occurs when a retailer adjusts the quantity of the item it purchases via wholesalers in response to a tiny shift in the actual or anticipated demand for the good. Because they do not have complete details about the shift in demand and the fact that wholesalers are not aware of demand shifts, they increase the amount of orders it receives from the manufacturer to an even greater amount while the manufacturer being further removed, will alter the quantity it produces in a larger way.

The term comes from a concept of science that states that the whip movements are similar to amplifying the movement from its source (the hand that is cracking the whip) to the final point (the end of the whip).

The downside caused by the effect of bullwhip is it increases the inefficiencies of a supply chain, as every step of the supply chain estimations demand in a way that is more and more inaccurate. This could lead to over-investment in inventory and revenue loss as well as a decrease of customer services, a delay in schedules, or even bankruptcies or layoffs.

Knowing the Bullwhip Effect

The bullwhip effect usually is felt from the retail level all the way up the supply chain until at the level of manufacturing. If a retailer is able to use the data from sales immediately to predict an increase in the demand for a product the retailer will send an order for more product on to the distributor. In turn, the distributor will relay the request to the manufacturer and manufacturer of that product. This is an element of supply chain operations , but does not necessarily reflect an effect called a bullwhip.

The bullwhip effect typically distorts the process in one of two ways. One is that the initial retail order changes are caused by an incorrect demand forecast. The magnitude of the error is likely to increase as it advances further through the supply chain until the manufacturer. Another instance occurs when the retailer has exact information regarding demand, however, it can lead to inaccurate conclusion about the details of the reasons and the specifics of the order changes made by the retailer is lost, resulting in inaccurate assessments made by wholesalers that are then amplified further along the chain.

 

An example of the bullwhip effect.

Imagine the possibility of a hot chocolate shop that usually sells 100 cups per day during winter. On an especially cold day in the region the store sells 120 cups rather than. Conceiving the sudden growth in sales as more general trends the company requests the components for 150 cups directly from its distributor. The distributor notices the rise and extends his purchase orders with the maker in anticipation of more requests from other retailers too. The manufacturer expands its production run to anticipate greater demands for the product in the coming years.

 

Each time the demand forecasts have become ever more disorganized. If the retailer expects to see an increase in hot chocolate sales once the weather improves the retailer will discover that it has more stock than it needs. Manufacturers and distributors will be able to store even more stocks.

 

A different reason behind the absence of data is that logistical operations at the wholesale level can take longer to shift, meaning the conditions that caused the change in the demand on the retail side might have passed before the wholesaler was able to react. Since changing production outputs in manufacturing takes longer and the information from retailers is longer delayed in reaching manufacturers, the challenge in reacting properly to fluctuations in demand rises significantly.

 

Although the store an accurate assessment of the market demand, like because of the onset of the local hot chocolate festival the bullwhip effect could be present. The distributor, being not fully aware of the local climate might conclude that the problem is the result of a general increase in popularity of hot chocolate rather than the specific circumstances for the particular retailer. The manufacturer, even far removed from the market will be less likely to comprehend and react appropriately to the changes in demand.

The effects from the Bullwhip Effect

In the above example it is possible that the manufacturer will be left with a substantial excess of products. This can cause interruptions in the supply chain as well as the business of the manufacturer–increased expenses for transportation, storage spoilage, loss from revenue and delays in the delivery of goods, and so on. The retailer and the distributor in this case could encounter similar problems.

 

What does an Bullwhip Effect indicate?

A bullwhip effect is a sign that a minor mistake in assessing demand for consumer goods is amplified by the supply chain. This implies that communication between companies within a supply chain are inadequate, resulting in firms higher in the supply chain not having crucial information.

How do you recognize an Bullwhip Effect?

The effect of the bullwhip can be difficult to recognize at a glance as it is due to a lack of communication across the supply chain. Most often, it’s an event that is discovered later, after the inefficiencies have already been established.

 

How can you prevent the Bullwhip Effect?

There are numerous things that firms within supply chains can do to avoid or minimize the risk and magnitude of the bullwhip effect. In the first place, they should make sure that there is a clear and consistent communication between the companies in through the entire supply chain. This will prevent short-term or localized changes in supply from being interpreted as more extensive than they actually are. Businesses should be certain to consider a wider perspective when making forecasts of demand in order to minimize the impact of any short-term or temporary shifts. Additionally, businesses can try to improve the speed with they can react to changes in demand, which means that they are able to adjust their production more quickly even if they do not accurately assess the demand. This can also decrease the requirement to over-produce or order more to provide some buffer in case of shifts in demand.
