There are two main methods in forecasting software: quantitative and qualitative. Quantitative forecasts use data that can be measured, like sales data or business statistics. Qualitative data isn’t measurable, and it’s often derived from expert opinion and experience.
There are multiple approaches that fall under either quantitative or qualitative methods. An accurate forecasting tool takes all approaches into account when producing forecasts.
Exponential smoothing is one approach to quantitative forecasting. This approach uses historical data of demand to produce forecasts. It’s different from the moving averages method, and there are some advantages and disadvantages.
In exponential smoothing, there’s a value associated as a smoothing constant. This number is between 0 and 1. This is done because over time factors change, and forecasts need to reflect those changes. After mathematically determining a smoothing constant, it’s used as the exponent throughout the forecast. The success of exponential smoothing is partially dependent on the experiences and judgment of the demand planner.

Exponential smoothing is often used in visual aids and presentations. It’s often used in finance and economics settings. If there isn’t a clear pattern, the “smoothing” part of these graphs makes things easier to be explained and understood.
A real-life example can be seen in America’s favorite beverage company, Coca-Cola. Coca-Cola uses a simple exponential smoothing forecast. The stock market is unpredictable and hard to understand for many. Coca-Cola’s investors are often unaware of what the value of their stocks will be tomorrow.
Rather than moving averages with equally weighted values, this works better for them. Exponential smoothing allows Coca-Cola to have a more reliable vision of their near future because they can weight things depending on the age of their prices.
