Tell me about a time when measurement error drives the wrong engineering decision. What did you do?

I first confirmed the facts and contained the immediate impact. Next, I reviewed calibration certificate, MSA result, and master sample and coordinated the action to verify calibration status, resolution, method, operator technique, and GR&R. After verifying the result, I summarized the root cause, preventive control, owner, and follow-up plan so the issue would not recur.
