The goal of performing a failure modes, effects, and diagnostics analysis (FMEDA) is to predict important reliability and safety metrics including failure rates for each failure mode, automatic diagnostic effectiveness, useful life, latent fault test effectiveness. This information is used for many purposes including identification of weak areas in a design, warranty cost prediction, etc. But perhaps most importantly, FMEDA results are used to calculate the safety integrity of equipment designed for Functional Safety applications. These safety integrity metrics are an essential part of functional safety certification.
As valuable as the FMEDA results are, many find that the engineering time needed to perform a quality FMEDA is excessive. How can we do better? There are several techniques that are used by top FMEDA professionals to not only reduce engineering hours but increase analysis quality. One of the most effective techniques is to organize the FMEDA input information into functional blocks, with functions and failure modes for each block documented. exida calls this the Functional Failure Mode FMEDA process.

I learned about the Failure Modes and Effects Analysis (FMEA) process for designs some decades ago. I was Supervisor of an Embedded System development group. There seemed to be a lot of evidence that an FMEA on a design was a really good way to identify issues (problems) early in…
A variation of the DFMEA method has evolved from the application of Functional Safety requirements to the DFMEA process. exida calls this method DDMA – Design Deviation and Mitigation Analysis. DDMA maintains the essential objective of DFMEA to identify potential design issues early in the development and make design changes…
Good component failure rate data is a cornerstone of good quality reliability metric analysis. As mentioned in a previous exida whitepaper , one of the shortcomings of reliability databases has been the inability to handle variations in the operating environment. A sensor monitoring a flame and the processor interpreting the…
