Relying on historical demand to predict future needs can be inaccurate, especially if there are external changes affecting demand patterns. Order Batching: Companies may not order frequently, waiting instead until they need a large batch, causing sporadic spikes in demand. Price Fluctuations: Sales, discounts, and other promotions can result in increased demand, but these surges might not represent consistent purchasing patterns. Shortage Gaming: In the face of a product shortage, retailers might order more than required, anticipating limited supplies. Consequences: The bullwhip effect can have dire financial repercussions. Exaggerated demand forecasts can lead to overproduction, while underestimated demands can cause stockouts, both of which can be costly. This inconsistency in the supply chain can also lead to increased costs in warehousing, shipping, and manufacturing, impacting both manufacturers and retailers
