Product Code Changes

Because the quality staff never touches the actual product code, development management tends to forget the affect that their activities have on the source. Nobody, including the managers themselves, seems to know why this blindspot exists. If you stop and think, then the relationship is obvious, but in the heat of putting schedules together, bug fix times are often dropped.

Part of the reason may be that predicting the amount of time needed for bug fixes is hard. There are two variables and both are hard to guess

The best hope for making these estimates is historical data. If you don't have historical data, pick a reasonable number and assume that. When you figure out how wrong it is, you have a basis for your next guess.
