Time to Retire the MAPE

Abstract: Although forecasting researchers - and even most practitioners - have recognized the flaws in MAPE for many years, it remains a popular metric for reporting forecasting performance. This is largely because of its interpretability: MAPE is easy to understand by the business managers and executives who make decisions based on forecasts. But as more forecasting is done with small, intermittent quantities on a disaggregated level (such as product/location/day in retail), MAPE has become more and more problematic.
