CRE Failure Analysis & Testing

Question 1

What is the primary goal of failure analysis?

Accepted Answer

Determine root causes to prevent future failures

Answer

Increase system cost

Answer

Ignore failures and focus on production

Answer

Eliminate testing to save time

Question 2

Which method is commonly used in failure analysis?

Accepted Answer

Root Cause Analysis (RCA)

Answer

Random inspection without records

Answer

Ignoring minor failures

Answer

Relying on assumptions instead of data

Question 3

What is the purpose of non-destructive testing (NDT) in failure analysis?

Accepted Answer

Identify defects without causing damage

Answer

Break components to analyze them

Answer

Eliminate testing altogether

Answer

Increase stress on working components

Question 4

How does Failure Modes and Effects Analysis (FMEA) assist in testing?

Accepted Answer

Systematically identify and evaluate failure modes

Answer

Ignore potential failure points

Answer

Focus only on financial costs

Answer

Increase system complexity

Question 5

What is a key advantage of accelerated life testing (ALT) in reliability testing?

Accepted Answer

Predict lifespan by simulating extreme conditions

Answer

Reduce reliability by skipping testing

Answer

Avoid data collection in testing

Answer

Increase costs without improving performance

Question 6

Why is stress testing performed in failure analysis?

Accepted Answer

Identify weak points under extreme conditions

Answer

Reduce the need for quality control

Answer

Avoid failure data collection

Answer

Increase the rate of failures intentionally
