The Bullwhip Effect
• The downstream part of the supply chain generate the demand.
• For companies further upstream in the channel, demand is a compilation of orders from the companies downstream.
• Distortions in demand information can and do occur as we move further away from the end customer along the supply chain.
• Both the perceived demand seasonality and forecast error can increase as we proceed upstream in the supply chain.
• This phenomenon is referred to as the bullwhip effect.
