Abstract

Carl and Fred discuss the difference between the body of knowledge of reliability and safety, and how they work together.

Key Points

Join Carl and Fred as they discuss the different roles and responsibilities of reliability and safety activities.
Topics include:

• What is anticipated misuse of a product, and how is that incorporated into reliability applications?
• What is role of regulatory requirements in reliability versus safety?
• Difference between performance and safety requirements.
• How do the four elements in the definition of reliability relate to this discussion?
• Fail safe: We don’t want product to fail; but if it does we want it to fail safely.
• Risk analysis includes both severity and probability of occurrence. Severity assessment includes potential safety impacts.
• Fault tolerance and degraded performance
• Role of tradeoff studies in decisions about safety and reliability.
• In an FMEA, is it a failure if the product is used slightly outside the operating envelope? What if the failure is very severe?
• Discussion of concerns, and how they can be used as input to failure modes.
• Using AI as input to discussions, to be sure nothing is missed.
• Both Safety and reliability are essential in products.
• If product fails, ask what happens (the consequence).

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.
