The correct answer to this open question is "the lost-horse forecasting."
In 2019, a marketing manager for New Balance’s Fresh Foam Zante shoe needs to forecast sales through 2021. She begins with the known totals for 2018 and adjusts for positive factors like acceptance of new high-tech designs and great publicity, and for negative factors like higher inflation and predicted moves by the competition. This type of forecast is referred to as lost-horse forecasting.
In this kind of forecast, you first take into consideration the last known value of the article that is going to be forecasted, writing all the factors that might affect it in the forecast. Then you have to evaluate if that would have a positive or negative influence or impact in the article. Finally, you project a feasible situation.
