8.2 System Strength Score

The system strength score gives a consolidated view of the performance of the entire transaction monitoring system. This metric is computed by taking a simple average of the segment strength scores of all of the institution’s customer segments. The variance for each segment strength score is also aggregated to produce a confidence interval for this metric.

Limitations

As this metric is an average, it might obscure the poor performance of one or more segments. Even if the system strength score is high, monitoring the individual segment strength scores is important.
