Tell us about a time when you conducted root cause analysis for environmental failures. How did you determine the corrective actions?

In my previous role as an Environmental Test Engineer, I conducted a root cause analysis for an environmental failure during a product testing campaign. The failure occurred when the product was exposed to extreme temperature and humidity conditions. To determine the corrective actions, I first analyzed the test data and observed that the failure was due to inadequate sealing of the product. I then worked closely with the design and manufacturing teams to understand the root causes of the sealing issue. We conducted further tests and found that the failure was caused by a defect in the sealing material. I recommended corrective actions, which included implementing tighter quality control measures for the sealing process and using a more robust sealing material. These actions were successful in preventing similar failures in future testing campaigns.

In my previous role as a Senior Environmental Test Engineer, I conducted a root cause analysis for an environmental failure during a product testing campaign. The failure occurred when the product was exposed to extreme temperature and humidity conditions. To determine the corrective actions, I utilized my expertise in environmental testing methodologies and equipment. I analyzed the test data using statistical analysis tools, paying close attention to detail. Through this analysis, I identified that the failure was due to inadequate sealing of the product. I then worked collaboratively with the design and manufacturing teams to deeply understand the root causes of the sealing issue. We conducted additional tests and found that the failure was caused by a defect in the sealing material. Based on these findings, I recommended corrective actions which included implementing tighter quality control measures for the sealing process and using a more robust sealing material. These actions were effective in preventing similar failures in future testing campaigns.
