Sales forecasting is extremely important for an organization. Using the following information, develop a sales forecast for the next year for this firm using the Naïve Method (formula is Current Year x (Current Year/Previous Year)), the Moving Average Method (using both a two-year and a four-year average), the Exponential Smoothing Method (using an α = 0.2), and a Trend Projection (using Regression). Do you think these methods should all give you the same estimate? Why or why not? Make sure you show your work.
