Overview
The bullwhip effect is a common challenge in supply chain management. Demand variability at the consumer level causes exaggerated adjustments by wholesalers and manufacturers.
Causes

Impact
- Excess inventory or shortages
- Increased costs
- Poor customer service
Example
A small spike in retail sales for a product causes wholesalers to order larger quantities, eventually resulting in overstock at manufacturing plants.
