At Advance Auto Parts, we have replaced an old legacy forecast, which was creating a probability to sell, with a new forecast, which predicts a quantity to be sold. While doing this, we had to compare the two forecasts, in order to demonstrate that the new forecast is indeed better than the old one. This talks describes how we did the comparison and what kind of pitfalls we ran into.
