Effect and Likelihood

Abstract

Carl and Fred discuss a listener question on FMEA, about reducing the severity level through mitigation strategy. Specifically, can FMEA reduce the likelihood of the effect of failure?

Key Points

Join Carl and Fred as they discuss how FMEA deals with mitigation of the Effect of failure.

Topics include:

• How design change can mitigate seriousness of the effect of failure
• Strategies to reduce severity of a problem during operation
• FMEA design prevention methods
• Difference between likelihood of the Cause in an FMEA, and and likelihood of effect, not determined in FMEA
• FMEA does not quantify the likelihood the a bad event (effect)
• FMEA does assess the likelihood of the cause of failure
• What techniques will determine the likelihood of the bad event?
• FMEA can point to need for testing
• Relationship of FMEA with Hazard Analysis
• Proper use of FMEA
• Regulations that require FMEA can promote “checkbox”
• Interacting with regulatory bodies
• Use of Fault Tree Analysis to analyze unwanted event

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.
