First principle for great sales forecasts: 'good forecasting requires a good sales strategy'. Second principle: 'good forecasting requires an understanding of your buyer's behavior'. Thirth principle: 'good forecasting requires a milestone driven pipeline process'. Fourth principle: 'good forecasting requires continual improvement'.
The two general approaches to forecasting are quantitative methods, which rely on historical data and mathematical models to predict future outcomes, and qualitative methods, which use expert judgment, market research, and other non-numeric factors to make forecasts.
Some methods used for forecasting include using historical information and regression analysis. Analyzing historical information is important because future performance is a good indication of future performance. Regression analysis allows business to adjust their numbers based on differences in variables, which is beneficial if they expect to have significant changes that will make historical data invalid.
