One way to calculate this, and again its not a perfect metric, is to look at the trend data. What is the average number of times a particular incident has occurred month over month on average. This will become your baseline to compare against. After implementing a fix, trend that data and compare against the baseline. This can be your number of prevented incidents.
Not a perfect approach, but it is an approach. _________________ Adam

this is exactly what we've done in the past. It goes to showing how you managed to reduce occurance of certain types of incident through resolving a root cause. If nothing else has changed in your environment, looking at the trends should give you a pretty good idea about "preventing".
