Then it's a scenario model, which asks what-if questions usually for planning purposes (e.g., what's the most hospital beds we might need?). Scenario models can have longer time horizons than forecasts, but 6 months is still quite long.

That is a quite cool way of separating those models. Can you point me in a direction where I could learn more? RE: Forecast vs Scenario?

It's the same thing. Just the latter implies you're identifying an assumption or two as variable and modeling outcomes of some of them changing. They're all forecasts. To argue otherwise is semantic pedantry.
