Trend Projection
Analyzes historical sales data to predict future trends. The simplest method.
Market Research
Incorporates survey data for customer demand insights. More time-intensive but provides additional perspective.
Examples of Demand Forecasting
Here are some examples of how companies use demand forecasting:
Seasonal Business Forecasting
A company that sells seasonal products like costumes can use 3-year sales averages to predict yearly demand fluctuations based on historically high and low seasons.
