True or False: Assumptions are necessary for forecasting numbers.

• A. True
• B. False
• C. It depends
• D. Not necessarily

Answer: (A)

Forecasting numbers rests on making informed assumptions about future conditions, because you can’t predict the future without some basis for how things will unfold. When you project outcomes, you’re choosing scenarios for factors like demand, pricing, costs, weather, and other variables. Those choices are assumptions about what is likely to happen, and the forecast depends on them. Even methods that rely on historical data implicitly assume that past patterns will continue into the future, which is itself an assumption about stability or the persistence of relationships. Because of that, forecasts are built on assumptions, and acknowledging them is essential to understand what the numbers mean and how uncertainty is handled. Other options imply you can forecast without any assumptions or that it only sometimes depends on the method, but in practice any forecast requires a basis about future conditions, and alternative scenarios are used to reflect different possible assumptions.
