Demand forecasting is the process of estimating how much of a product or service consumers will buy in the future. It uses predictive analysis of historical data, as well as quantitative methods like current test market data, to help businesses make informed supply decisions. Accurate and timely forecasts are important for both businesses and their customers. 

The five most popular demand forecasting methods are: Trend projection, Market research, Sales force composite, Delphi method, and Econometric method. 
The econometric method uses data about demand and external elements that can affect demand to create a demand plan. For example, an increase in personal debt may coincide with an increase in demand for home repair services. 

Here are some steps in the demand forecasting process:
Define the future forecast period
Set a hypothesis
Select the right forecasting method
Build your base forecasting model
Check for forecast errors
Test simulations within this hypothesis
Build your inventory plan
Track real-time data
