The Bullwhip Effect

What is the Bullwhip Effect?

The bullwhip effect describes how small fluctuations in consumer demand at the retail level can create increasingly larger swings in orders as you move upstream through the supply chain. Like cracking a whip, a small movement at one end creates an amplified wave further along.

In the US beverage alcohol industry, this effect is particularly pronounced due to the three-tier system mandated by law, where products must flow from producers through distributors to retailers before reaching consumers.

Why does this happen? Each tier makes ordering decisions based on its own demand forecasts, lead times, & safety stock policies. They cannot see end consumer demand directly, only orders from the next tier down. This information delay, combined with batch ordering, minimum order quantities, & protective safety stocks, causes demand signals to amplify upstream.
