Review Questions

• How does effective demand forecasting influence inventory management and resource allocation in an organization?
  • Effective demand forecasting allows organizations to anticipate customer needs accurately, which leads to better inventory management and resource allocation. By predicting future demand, businesses can ensure they have the right amount of stock on hand to meet customer orders without overstocking or running out of products. This balance not only reduces holding costs but also enhances customer satisfaction by improving service levels.
• What are the key differences between qualitative and quantitative methods of demand forecasting, and when should each be applied?
  • Qualitative methods rely on expert opinions and insights when historical data is scarce or unreliable, making them suitable for new products or rapidly changing markets. In contrast, quantitative methods use statistical analysis of historical data to predict future demand, making them more appropriate for established products with consistent sales patterns. Choosing the right method depends on the availability of data and the specific context of the forecasting situation.
• Evaluate the impact of seasonality on demand forecasting accuracy and discuss strategies to mitigate its effects.
  • Seasonality can lead to significant fluctuations in demand that challenge forecasting accuracy. For instance, products may see spikes in demand during holidays or specific seasons. To mitigate these effects, businesses can use seasonal adjustment techniques in their forecasting models, analyze historical sales data for patterns, and implement flexible inventory strategies that allow them to scale production up or down based on anticipated seasonal changes. Incorporating these strategies helps improve overall forecast accuracy and responsiveness to market demands.
