How to do demand forecasting
Demand forecasting can be done using several methods, including:
- Qualitative methods: These methods rely on expert opinions, market research, and other non-quantitative data to estimate future demand. Qualitative methods are useful when historical data is not available or when market conditions are changing rapidly.
- Quantitative methods: Based on historical sales data and statistical models to estimate future demand. Quantitative methods are useful when historical data is available and when market conditions are relatively stable.
Some common quantitative methods for demand forecasting include:
- Moving average: This method involves calculating the average of the last n periods of sales data. The resulting average is used to forecast future demand.
- Exponential smoothing: This method involves giving more weight to recent sales data and less weight to older data. The resulting forecast is a weighted average of past sales data.
- Seasonal forecasting: This method involves analyzing historical sales data to identify seasonal patterns in demand. The resulting forecast takes into account seasonal fluctuations in demand.
Which method of forecasting helps to smooth sudden fluctuations in demand?
Exponential smoothing is a method of forecasting that helps to smooth sudden fluctuations in demand. This method gives more weight to recent sales data and less weight to older data, which helps to reduce the impact of sudden changes in demand. Exponential smoothing is particularly useful when demand is subject to random fluctuations or when there are sudden changes in market conditions.
