What is forecast accuracy and how can it be improved?

• A. A subjective feeling about how confident you are in the forecast.
• B. The difference between forecasted and actual results expressed as a percentage.
• C. The probability that forecasts will be perfect.
• D. Degree to which forecast matches actual results; improve with data-grounded assumptions, sensitivity analysis, and updates.

Answer: (D)

Forecast accuracy is the degree to which your forecasted results match what actually happens. It’s not about how confident you feel, and it isn’t about the forecast being perfectly correct every time. It’s about how close the predicted numbers are to reality, across the relevant outcomes. To improve forecast accuracy, ground your assumptions in solid data and historical patterns rather than guesswork. Use data-backed inputs so the forecast reflects real trends, seasonality, and relationships between variables. Conduct sensitivity analysis to see how changes in a few key drivers (like price, demand, or market growth) impact the forecast, which helps you understand where the model is most vulnerable. Finally, keep forecasts current by updating them as new data comes in, so they reflect the latest information and shifts in the environment.
