A recent college graduate was hired by a whole foods store as an operations planner. The owner of the store thought kale should be forecasted using smoothing value of 0.1, while the Operations manager felt a smoothing value of 0.3 would be better. Using F1=175 and the Kale demand below, which of the two managers is right and why?
[Tip: Once you caluclate the forecast values for each week, be sure to calculate the forecast errors using the three Forecast Error models presented in Chapter 9 to guide your choice.]
