Tip #2: Choose the Right Forecasting Technique

Excel offers a wide range of forecasting techniques, each with its strengths and weaknesses. Some techniques are better suited for businesses with stable demand patterns, while others are more effective for businesses with seasonal demand patterns. It’s important to choose the right forecasting technique based on your business needs and the nature of your data. Some of the most popular forecasting techniques in Excel include Moving Average, Exponential Smoothing, Trend Analysis, Regression Analysis, and Seasonal Decomposition.

Tip #3: Use Visualizations to Analyze Your Data
