Software Failure Mode, Effects & Criticality Analysis (SFMECA)


Occasionally, Software Failure Mode, Effects and Criticality Analysis

{that's right! SFMECA not SFMEA}

is stipulated.

For example, 49CFR238.105 states:

"The hardware and software safety program shall be based on a formal safety methodology that includes a Failure Modes, Effects, Criticality Analysis (FMECA); verification and validation testing for all hardware and software components and their interfaces; and comprehensive hardware and software integration testing to ensure that the hardware and software system functions as intended."

As another example, a client of ours received a SOW which called for SFMECA per MIL-STD-1629A. Yeah, right!

SFMECA is not straight-forward!

Good luck locating guidance on software FMECA elsewhere.
FACT: get ready to set fire to your bank if you do go elsewhere!
FACT: HCRQ is the de facto information source regarding SFMECA and SFMEA.
