Quantitative & Qualitative Forecasting Techniques For Your Supply Chain. Quantitative forecasting methods use past data to determine future outcomes. The formulas used to arrive at a value are entirely based on the assumption that the future will majorly imitate history. In addition to forecasting expected outcomes, forecasters should assess uncertainty. Chatfield addresses this issue with respect to quantitative This technique for producing forecasts implicitly would not produce good forecasts when data are not independent or when causal factors have to be. Two Corning Glass Works products illustrate the use of various forecasting techniques. Managers and forecasters should consider three issues when approaching a forecasting problem: the purpose of the forecast, the dynamics and components of the system, and the importance of the past in estimating the future. The three basic forecasting methods are. Naive forecasting models are based exclusively on historical observation of sales or other variables, such as earning and cash flows. These models do not attempt to explain the underlying causal relationships that produce the variable being forecast. Smoothing techniques are a higher form of naive models.

Quantitative forecasting can be characterized by one of the two basic techniques: Time Series – The future will tend to look and behave like the past. For example, gasoline prices for the next six months will continue along the same lines as they have over the past six months. We devote the rest of this chapter to quantitative forecasting.
