What are the principles of Design Failure Mode and Effects Analysis?
A reliability engineering question about DFMEA methodology.
Why Interviewers Ask This
DFMEA is a proactive tool for risk reduction. Interviewers want to know if you understand how to identify and mitigate design risks before production.
How to Answer This Question
Explain the systematic approach: Identify potential failure modes, determine effects, assign severity, occurrence, and detection ratings. Calculate RPN and prioritize actions. Emphasize prevention over detection.
Key Points to Cover
- Failure mode identification
- Effect analysis
- RPN calculation
- Prevention focus
Sample Answer
DFMEA principles involve systematically identifying potential failure modes in a design and analyzing their effects on the system. Teams assign Severity, Occurrence, and Detection scores to calculate Risk Priority Number…
Common Mistakes to Avoid
- Confusing with PFMEA
- Ignoring effect analysis
- Not prioritizing actions
