RAM Commander contains multiple failure analysis methods:

FMECA (MIL-STD-1629A, GJB 1391, GJB 1392 etc.) with Testability Analysis

Process/Design FMEA (AIAG, QS-9000, SAE J 1739, IEC 60812, JEP131)

Fault Tree Analysis - deductive analysis performed to determine all combinations of events leading to a single general conclusion or hazard/failure.

Event Tree Analysis - inductive failure analysis performed to determine the consequences of single failure for the overall system risk or reliability.

Mentioned failure analysis methods may use product tree data and reliability/maintainability analysis results.
