Our function here is to present an outline of this discipline by discussing the best way a company must approach a forecasting drawback, describing the strategies out there, and explaining how to match technique to problem.

Generally forecasting is merely a matter of calculating the corporate's capacity—however not ordinarily. As with time collection analysis and projection techniques, the previous is important to causal models.
