FMEA stands for Failure Mode and Effects Analysis.
Potential FMEA is an analytical technique utilized to assure that as a mean to assure that potential failure modes and their associated causes/mechanisms have been considered and addressed to the extent possible. Corrective actions are suggested and selected for implementation, and a control plan is formed as a part of the procedure.
Potential FMEA deals with Severity, Occurrence and Detection rankings. Multiplication of these three ranks gives us a Risk Priority Number (RPN), which is an integrated measure of risk.
Any entity like product, process, software, or system may be a subject of this analysis.
The screenshot below illustrates FMEA example done using RAM Commander software:
See RAM Commander Potential FMEA Software Module for more information about this FMEA type.
2. Hardware FMEA and FMECA (Failure Mode, Effects and Criticality Analysis) is one of the major components of system reliability analysis. It is required and compatible with MIL-STD-1629A and other standards (like GJB 1391, GJB 1392, AIR FORCE SMC REGULATION 800-31 and more). Many standards and regulations for aerospace, defense, telecommunications, electronics and other industries require that FMECA analysis must be performed for all designed/manufactured/acquisition systems, especially if they are mission or safety critical.
FMECA module uses a product tree previously created for the reliability analysis purposes. It also incorporates reliability and maintainability information received as a result of reliability and maintainability analysis.
The screenshot below illustrates FMECA example provided by the RAM Commander software:
See RAM Commander FMECA and Testability Software Module for more information about this FMEA type.
