Bullwhip Effect
The bullwhip effect is a phenomenon in supply chain management where small changes in consumer demand lead to larger fluctuations in orders placed upstream. This effect can cause significant variability in inventory levels as companies respond to perceived changes in demand. Originating from research by Jay Forrester, it highlights the challenges of accurately forecasting demand and managing inventory.
- ▪The bullwhip effect results in amplified demand variability as one moves upstream in the supply chain.
- ▪A fluctuation in point-of-sale demand of five percent can be interpreted as a change in demand of up to forty percent by supply chain participants.
- ▪The concept was first introduced in Jay Forrester's Industrial Dynamics in 1961.
