Bullwhip Effect

The Bullwhip Effect is a supply chain phenomenon in which small changes in customer demand become progressively amplified as demand signals and replenishment orders move upstream through the supply chain. As each tier reacts to perceived demand, variability increases, leading to larger fluctuations in orders, inventory levels, and production activities further upstream.

What causes the Bullwhip Effect?


The root cause of that phenomenon is planning based on distorted demand signals instead of actual market demand (Nervous Planning).

But there are other causes that amplify the effect:
• Lack of visibility across the supply chain.
• Long lead times
• Order batching
• Price fluctuations and promotions
• Rationing and shortage gaming
