We miss the forecast almost every quarter. How do I actually fix accuracy?
Start by measuring it properly, because most teams grade themselves against a forecast they revised in week eleven. Forrester's definition is the honest one: accuracy is the gap between the day one forecast and the final result, and within plus or minus five percent is excellent, beyond ten percent is a real miss. Roughly four in five sales organisations miss by more than ten percent, so you are not unusual, you are just measuring late. Then fix the two causes. Upstream: stage definitions nobody can game and a monthly pipeline scrub, since a forecast built on fictional pipeline cannot be rescued by a better model. Downstream: track forecast accuracy per manager as its own scored metric, and visibly reward the manager who calls a smaller number correctly over the one who calls a big number and misses.
