Bullwhip Effect
The Bullwhip Effect is a common supply chain phenomenon where small changes in customer demand lead to increasingly larger swings in inventory and order levels as you move up the supply chain (from retail to distributors to manufacturers to suppliers). Think of it like a game of telephone, where information gets more distorted at each step. Supply chain professionals need to understand this concept because it can cause excess inventory, stockouts, higher costs, and poor customer service. Companies like Walmart and Procter & Gamble often look for candidates who can help prevent or minimize this effect through better forecasting and planning.
