Review Questions

• How does demand forecasting influence supply chain management decisions?
  • Demand forecasting plays a pivotal role in supply chain management by providing critical information needed for inventory planning and production scheduling. Accurate forecasts help businesses determine how much product to produce or order, preventing issues such as stockouts or overstock. Additionally, effective demand forecasting enables companies to better manage their resources, negotiate supplier contracts more efficiently, and align logistics operations with expected customer needs.
• Discuss the implications of inaccurate demand forecasting on a company's supply chain costs.
  • Inaccurate demand forecasting can lead to significant cost implications for a company’s supply chain. For instance, if forecasts are too high, the company may incur excessive holding costs due to overstocking inventory that may not sell. Conversely, underestimating demand can result in stockouts, lost sales, and dissatisfied customers. These scenarios highlight the importance of precise forecasting methods in maintaining cost efficiency within the supply chain.
• Evaluate the role of technology in enhancing the accuracy of demand forecasting within supply chain management.
  • Technology has revolutionized demand forecasting by enabling businesses to leverage advanced analytics and machine learning algorithms. These tools analyze vast amounts of data from various sources to identify trends and patterns that human forecasters might miss. By utilizing real-time data processing and predictive modeling, companies can create more accurate forecasts that adapt to changing market conditions. This not only improves inventory management but also enhances overall supply chain agility and responsiveness to customer demands.
