Definition

The bullwhip effect occurs when minor changes in customer demand amplify as they move upstream, leading to overstocking or stockouts.

Overview

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

  • Forecasting errors
  • Order batching
  • Price fluctuations
  • Lead time variability

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.
