Causal Forecasting is also a type of Quantitative Forecasting technique, which uses Statistical Forecasting models based on historical sales data and factors which can influence future demand. The entire concept behind demand forecasting is to ensure that you are fulfilling orders on time in the most efficient method/way possible. Some of the examples of Extrapolative Forecasting are Moving average method, Weighted moving average, and Exponential Smoothing. A forecast is a statement about the uncertain future (such as weather forecast). Extrapolative Forecasting is a type of Quantitative Forecasting technique, which uses time series methods to project demand based on the past sales of a specific product category under normal conditions. Forecasts are developed for a company’s finished goods, components and service parts. Non-statistical forecasting is found in supply chain management software where demand is forecasted based on quantities determined by the production planners. This is why you need to ensure that you understand the characteristics and methods associated with proper demand forecasting and locate a method that enables your company to meet demand in an efficient and on-time manner.
