Forecasting at different horizons

Forecasting is a structured estimate for a defined decision, horizon and level of detail. This guide introduces forecasting at different horizons and shows where it fits in a practical planning cycle.

Treat judgment around forecasting at different horizons as a measurable input. Store the statistical forecast, human adjustment and eventual outcome separately so their contributions can be reviewed.

First experiment

Review error by horizon and segment; an average can conceal a severe miss on a critical item.
