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.

Fixing critical bugs in a system is like surgery—precision matters, and you don’t want new wounds popping up. Start by implementing thorough testing: post-fix, hammer the system with regression and user acceptance testing (UAT) to snag any sneaky side effects before they hit live. Next, use version control: tools like Git let you track every tweak, so if something goes sideways, you can pinpoint and rewind with ease. Finally, conduct code reviews: fresh eyes from peers catch gremlins you might miss, boosting code quality and keeping the system rock-solid. It’s about rigor—test hard, track smart, and double-check. That way, you squash bugs without spawning new chaos.

1. Identify the full scope of the critical bug. 2. Determine the fix for the critical bug involving all members of the team 3. Implement the fix(es) and develop unit testing around this fix(es). 4. Code Reviews completed that code meets business needs, identifying any code quality issues, and ensuring unit test coverage is appropriate. 5. Developing a solid test plan to address the issue, gaps, and reviewing with the team. Implementing these changes to an automation framework to ensure that it is covered going forward. 6. Bugs and concerns need to be addressed as found. 7. After the dust settles, the team needs to triage what happened, and develop and implement a corrective action plan to try not to repeat the same mistake.

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.

- Analyze the root cause before applying a fix to prevent related issues. - Perform impact analysis to understand which areas might be affected. - Conduct thorough regression testing to ensure existing functionality works fine. - Use automated tests to quickly catch potential side effects. - Follow code reviews and peer testing for additional validation. - Implement CI/CD pipelines to detect issues early in development. - Continuously monitor post-release to catch unexpected behavior.

We go through root cause analysis , do regression test, do part in peer review . check after, fixing bug not affect existing modules of the application.

Absolutely, maintaining system stability while fixing critical bugs is a common challenge. Here are some additional strategies I’ve found effective: 1. **Automated Testing**: Implement automated testing frameworks to run a suite of tests every time a change is made. This helps catch regressions and new issues quickly. 2. **Continuous Integration/Continuous Deployment (CI/CD)**: Use CI/CD pipelines to automate the build, test, and deployment processes. This ensures that changes are integrated and tested in a consistent environment, reducing the risk of new issues. 3. **Monitoring and Logging**: Set up robust monitoring and logging to track system behavior in real-time.
