Testability Analysis
Failure Mode, Effects and Criticality Analysis (FMECA) is a natural continuation, and in many cases inseparable part of the Reliability Analysis. Previously a separate software package, FMECA is now a fully-integrated RAM Commander module. FMECA software tool uses a product tree previously created by the RAM Commander user for the reliability analysis purposes.
The RAM Commander FMECA module is suitable for both hardware and functional approaches to FMECA, and fully complies with MIL-STD-1629 A, commercial standards, and Good Manufacturing Practice (GMP) requirements, and supports the functional safety analysis according to IEC 61508. RAM Commander FMECA software module makes the FMEA process easy and visible: the product tree and the corresponding to each item sequence of Failure Modes => Next Higher Effects => End Effects are totally visible in the same window.
Extensive use of the FMECA Libraries facilitates the process even more and contributes to the accuracy of the performed analyses and reports. You can perform both the FMEA and FMECA calculating failure mode ratios, conditional probabilities and item criticality numbers.

Testability Analysis
Testability Analysis sub-module of the FMECA module is intended for in-depth Testability analysis. The main characteristics of Testability – BIT/Detection Coverage and Fault Isolation Resolution – can be calculated for each maintenance level (Organizational, Intermediate, Depot) and for specific detection methods (BIT, BITE, external test equipment, etc.). Test method efficiency and indication are defined for each test method or a group of test methods.Testability analysis is widely used for the development of necessary supporting documentation: maintenance manuals, troubleshooting procedures and inspection requirements.
Test coverage report shows the percentage of failures covered by a chosen test.
