The Rome Air Development Center Technical Report A Rationale and Approach for Defining and Structuring Testability Requirements defines several metrics that are supplied (under different names) within eXpress. The following table lists the applicable metrics in this document and their eXpress equivalents.

Testability Metric	eXpress Equivalent	eXpress Report
Fraction of Faults Detected	Total Probability Detected	Detection Order Report
Fraction of Critical Faults Detected	Total Probability Detected (with Diagnostics constrained to a subset containing only Critical Faults)	Detection Order Report
Fraction of Faults Isolated	Cumulative Pctg. (Cum %) column in Isolation Probabilities Using Testing Only	Fault Isolation Report
Fraction of False Pulls	1.0 - Isolation Effectiveness	Fault Isolation Report
Mean Fault Isolation Time	Expected Time to Isolate	Fault Isolation Report
Maximum Fault Isolation Time	Maximum Time to Isolate	Fault Isolation Report
