Limitations of traditional forecasting methods.

Traditional forecasting methods, while foundational to supply chain management, often struggle to keep pace with the inherent volatility and complexity of modern ecommerce. These techniques, frequently rooted in historical data and linear regression, assume a degree of stability that rarely exists in dynamic markets. Their reliance on past patterns can lead to significant inaccuracies when faced with unforeseen events, rapid shifts in consumer behavior, or novel product introductions, leaving businesses ill-equipped to respond effectively.

One of the primary limitations of conventional forecasting is its reactive nature. Models are typically built and updated periodically, meaning they are always playing catch-up with the latest market trends. This lag can result in considerable miscalculations, particularly for fast-moving consumer goods or during periods of significant promotional activity. The inability to anticipate sudden demand surges or drops leaves inventory managers in a constant state of reactive adjustment.
