The correct answer is: The bullwhip effect

The phenomenon where slight variations in demand at the consumer end of the supply chain lead to larger fluctuations in demand further upstream is known as the bullwhip effect. This occurs because each entity in the supply chain adjusts its orders based on perceived demand signals, often amplifying changes rather than smoothing them out. For example, if a retailer observes a small increase in customer demand, they might order significantly more inventory than necessary to avoid stockouts, prompting wholesalers and manufacturers to further increase their production and order quantities in response to the perceived increase in demand. As a result, the bullwhip effect can lead to inefficiencies such as excess inventory, stockouts, and increased costs along the supply chain. Understanding this effect is crucial for businesses seeking to optimize their inventory management and improve coordination among supply chain partners. Addressing the bullwhip effect involves strategies such as improved demand forecasting, clearer communication, and collaboration across the supply chain to smooth out demand variability.
