Which term of forecasts is generally considered to be more accurate?

1. Long term

2. Medium term

3. Short term

4. Very long term

The correct answer is: Short term

Short-term forecasts are generally considered to be more accurate due to several key factors. In the context of supply chain management and forecasting, short-term forecasts typically cover a period from a few days to a few months ahead. This relative proximity allows for more reliable data to be used, as historical patterns and trends are fresher, and there is less uncertainty involved compared to longer-term forecasts. Additionally, short-term forecasting often relies on more concrete, immediate data, such as recent sales figures, inventory levels, and customer orders. This leads to greater precision in predicting outcomes, as these variables can be closely monitored and adjusted in real-time. As forecasting periods extend—medium term to long-term—uncertainties increase, affecting the precision of predictions. Factors such as market fluctuations, changes in consumer behavior, and shifts in economic conditions become harder to predict accurately over longer time frames. For instance, long-term forecasts may depend on broader economic trends or changes in technology, which are inherently more unpredictable. Hence, the nature of short-term forecasting, with its reliance on recent data and closer alignment to current conditions, tends to yield more accurate results compared to forecasts with longer horizons.
