Bullwhip effect
Sidst opdateret 14. august 2023
What is a bullwhip effect?
The bullwhip effect is a phenomenon that occurs in supply chain management when small changes in demand at the retail level lead to larger and more volatile changes in demand at the wholesale, manufacturing, and raw material levels. This can lead to inefficiencies and disruptions in the supply chain, such as , overproduction, and excess inventory.
When does it occur?
The phenomenon is often caused by a lack of communication and coordination among the different parties in the supply chain.
For example, if a retailer experiences an unexpected increase in demand for a product, they may place a large order with their wholesaler to ensure that they have enough inventory to meet the demand. However, the wholesaler may not have an accurate picture of the retailer’s demand, and they may place a larger order with the manufacturer to cover the retailer’s orders.
This chain of events can continue up the supply chain, with each party placing larger and larger orders in response to the perceived increase in demand.
The bullwhip effect introduces a series of challenges such as stockouts and lost sales as suppliers are unable to keep up with the amplified demand signals or inaccurate forecasts and poor planning decisions.
How to avoid the bullwhip effect?
To avoid the bullwhip effect, businesses need to improve communication and coordination among the different parties in the supply chain. This can include using software to provide real-time visibility into demand data, implementing inventory optimization techniques to balance inventory levels and customer service levels, and implementing other supply chain management best practices.
