Review Questions

• How does demand forecasting influence inventory management strategies in global supply chains?
  • Demand forecasting directly impacts inventory management strategies by providing insights into expected product demand. Accurate forecasts enable businesses to maintain optimal inventory levels, ensuring they have enough stock to meet customer needs without overstocking. This balance helps reduce carrying costs and the risk of obsolescence while also preventing stockouts that could lead to lost sales and customer dissatisfaction.
• Discuss the role of technology in enhancing demand forecasting accuracy within global supply chains.
  • Technology plays a vital role in enhancing the accuracy of demand forecasting through tools such as machine learning algorithms and big data analytics. These technologies analyze vast amounts of historical sales data, customer behavior patterns, and market trends to identify correlations and predict future demand more reliably. By leveraging real-time data and advanced analytics, companies can improve their decision-making processes, adapt quickly to changing market conditions, and optimize their inventory management.
• Evaluate the implications of inaccurate demand forecasting on global supply chain efficiency and customer satisfaction.
  • Inaccurate demand forecasting can severely disrupt global supply chain efficiency by leading to either excess inventory or stockouts. Excess inventory ties up capital and increases storage costs while risking obsolescence. On the other hand, stockouts can result in missed sales opportunities and damaged customer relationships due to unmet demand. Both scenarios highlight the critical need for reliable forecasts to maintain an agile supply chain that can respond effectively to consumer needs and market fluctuations.
