5 Methods of Demand Forecasting

There are five key methods businesses use to forecast demand.

Analyze past sales data to predict future demand. Techniques like moving averages or exponential smoothing can identify trends and seasonality.

Analyzing real past customer data can be invaluable in helping you predict how future sales may go.

2. Trend analysis

Trend analysis looks at the broader market to understand long-term movements that affect demand. For example, the rise in eco-friendly trends can impact product demand.

5. Industry expertise

Leverage expert knowledge and experience to complement quantitative data. This hybrid approach is useful when data is limited or when predicting new market trends.
