Constructing a FMECA / FMEA in Reliability Workbench

The FMECA Module of Reliability Workbench provides the full framework and reporting facilities to allow users to construct FMECAs and FMEAs to MIL-STD-1629A, GJB 1391-92, BS 5760 Part 5, AIAG & VDA, SAE J1739, ARP5580 and similar standards, as well as customizing the FMEA or FMECA to the user’s own requirements. In addition, Process and Design FMEAs and commercial aircraft FMEAs may also be constructed and analyzed within this module.
The Reliability Workbench FMECA module has been tested and certified by SGS-TÜV as suitable for safety analyses according to ISO26262.

What is FMEA?

A Failure Mode & Effects Analysis is a step-by-step approach for identifying all possible failures in a design, a manufacturing or assembly process, or a product or service.

What is FMECA?

A Failure Mode & Effects and Criticality Analysis is similar to a FMEA but assigns severity rankings or weights to determine the criticality of individual failures.

Process and Design FMEA

Process and Design FMEAs provide an alternative approach to performing a Failure Mode and Effect Analysis. Occurrence, severity and detection rankings replace apportionments and failure rates. Risk Priority Numbers (RPN) are calculated by multiplying the severity, occurrence and detection ranking numbers together.

Commercial Aircraft FMEA

Commercial Aircraft FMEAs are a special format of FMEA allowing users to define failure modes and effects at unit, system, engine and aircraft level.
