Evaluate the Performance of the Rules in Production

Use the Rule Summary report to make sure the counts are what you expect.
Use the Rule Detail report to review specific accounts to make sure you are capturing the specific accounts you expected.
Run the False Positive Ratio by Rule report to view how well the rule is performing in production.
If you suspect the perpetrators have given up on a particular fraud behavior, then deactivate the related production rules to minimize your false positives.
Use queue reporting to further evaluate your rules (based on their associated queue definitions).
