Problem: You have just taken over as the new forecasting analyst for Fritos sales to Intermountain convenience stores. Despite having years of sales data showing flat demand with moderate variation, your predecessor used a 4-week moving average to project sales. Which adjustment would you make to the forecasting method in order to improve accuracy? Create a trend forecasting model. Implement an exponential smoothing model. Simplify the approach with a naive model. Increase the number of weeks used in the moving average model.
