If a data integration process has issues after standard checks, which action is most appropriate as the next step?

• A. Update dependencies
• B. Asking a senior engineer for peer review of the code
• C. Reboot the system
• D. Rewrite the script in another language

Answer: (B)

When a data integration process still has issues after standard checks, bringing in a senior engineer for peer review is the best next step. A seasoned reviewer can examine the data transformations, data mappings, error handling, and integration points with a fresh perspective, helping identify root causes that may not be obvious to the original author. This collaborative check reduces the risk of introducing new problems and helps verify that fixes align with standards, logging, and test coverage.

Updating dependencies could introduce new, unseen issues and isn’t a diagnostic step. Rebooting the system might clear temporary states but doesn’t address the underlying logic or data problems. Rewriting the script in another language adds unnecessary risk and complexity without diagnosing the failure.
