How can forecasting errors be reduced?

What is a good forecasting accuracy?

Q: What is the minimum acceptable level of forecast accuracy? ... Therefore, it is wrong to set arbitrary forecasting performance goals, such as “ Next year MAPE (mean absolute percent error) must be less than 20%. ” If demand is not forecastable to this level of accuracy, it will be impossible to achieve the goal.

Why forecasting is not always accurate?

Meteorologists use computer programs called weather models to make forecasts. Since we can't collect data from the future, models have to use estimates and assumptions to predict future weather. The atmosphere is changing all the time, so those estimates are less reliable the further you get into the future.
