Differing FMEA Approaches

Abstract

Carl and Fred discuss their overall approach to FMEA, what works and doesn’t work.

Key Points

Join Carl and Fred as they discuss how they approach FMEA to keep it lean, effective and workable. Topics include:

• Does a longer FMEA make for a better FMEA?
• If you have the right FMEA team and no one is concerned about a problem, no need to include it in the FMEA.
• Not seeing forest for trees is high risk
• Bottom-up FMEA vs Top-down FMEA
• Problems with “Bottom-up FMEA”
• Even lower-level FMEAs begin with functions
• FMEAs use engineering judgment
• Human judgment of FMEA team members is critical part of process
• There is not the time or bandwidth to FMEA everything
• Benefits of starting with System FMEA
• FMEA “nesting”
• Tracing component failure propagation to next level and up to the system is critical to assessing risk
• If one person on an FMEA team is concerned about an issue, the team needs to discuss the issue

Enjoy an episode of Speaking of Reliability. Where you can join friends as they discuss reliability topics. Join us as we discuss topics ranging from design for reliability techniques to field data analysis approaches.
