You're tasked with fixing critical bugs in the system. How do you ensure new issues don't arise?
When you're tasked with fixing critical bugs, maintaining system stability is key. Here’s how you can ensure new issues don't arise:
- Implement thorough testing: After fixing bugs, run extensive tests, including regression and user acceptance testing \(UAT\), to catch any unforeseen issues.
- Use version control: Track changes meticulously with version control systems like Git to easily identify and roll back problematic updates.
- Conduct code reviews: Regular peer reviews can catch potential issues early, ensuring higher code quality and stability.

Automated regression testing is invaluable. With the addition of a continuous integration (CI/CD) pipeline, build, integration, and regression issues can often be identified early, and receive fast feedback. If these are not available yet, or the automation tests do not have good code coverage, having a checklist of manual tests can help in the meantime.

Before deploying any bug fixes, we run them through our automated test suite and stage them in a duplicate production environment. We've implemented a "triple-check" protocol where changes must pass unit tests, integration tests, and load testing before deployment. Critical fixes undergo peer review from at least two senior developers. We maintain detailed deployment logs and use feature flags to quickly disable problematic changes if needed. Additionally, we've created a "stability checklist" that must be completed before and after each fix deployment, including database performance checks and monitoring of key system metrics. This systematic approach has significantly reduced the occurrence of secondary issues from bug fixes.

1. Find the real issue, not just the symptoms. 2. Check how the fix impacts other areas. 3. Get the code reviewed. 4. Test properly. 5. Monitor logs to catch new problems early.

The best strategy is tracking effectively all issues realizing that they will all pose a huge risk to the overall outcome. When dealing with fixing bugs or developmental issues if not tracked properly then you can have a team that have many different ways to fix, but no set.streamlined way towards resolution. Testing, tickets and review are key steps but I would add time based discussions on delay deficits and how to better overcome and layer solutions to solve. Sometimes we can't just get caught up in the bug fixes and move on. We need to see the ying and yang of development to ensure that we as a team aren't missing steps or compliances just to get to a promised ETA.

I prioritize a thorough root cause analysis before implementing fixes to avoid unintended side effects. Regression testing is conducted to ensure existing functionality remains intact after the fix. Automated test suites are updated to cover edge cases and prevent similar issues in the future. Code reviews and peer testing help catch potential flaws before deployment. Incremental rollouts and monitoring allow for early detection of any new issues. Continuous feedback loops with developers and QA teams ensure ongoing improvement and stability.
