When it comes to solving backend bugs, it's essential to follow a systematic approach to ensure that the bugs are identified and resolved holistically. Here's a step-by-step problem-solving approach for backend Devs:
Detailing the Problem (Root Cause Analysis):
- Begin by clearly defining the bug you have encountered. Understand the effects, logs, and any related customer issues.
Reproduce the Issue using RCA:
- Try to reproduce the problem in a local or test environment if possible. This step helps ensure that you understand the problem thoroughly and can be used for verification purposes.
Fixing:
Identifying a solution to the bug can be the most tricky part as fixing it might cause unintentional consequences and can accelerate the Bathtub Curve upside
Considering the category of bug fix is Code Change, identifying all areas of impact is necessary and mentioning it on the ticket before proceeding with the fix helps QA figure out all test cases that they will need to execute and the timeline for validation.
Updating the Backend Automation testing:
- One fix is delivered for QA to validate, Updating the backend automation testing using RCA in the area where the bug was identified as well as possibly other areas where similar bugs can be raised will help to improve the overall stability of the software
Collaborate and Seek Help:
- Sometimes what is unseeable to you might be very clearly visible to another pair of eyes. Seeking help or asking collaboration can effective reduce overall turnaround time. My own thumb rule on this is, if I am unable to figure out RCA or fix it within 1 hour, I will go for this option
Document the Solution:
- Document the problem, root cause, and the steps taken to resolve it. This documentation will be valuable for future reference and for sharing knowledge with team members.
Remember that debugging and problem-solving are iterative processes. It's essential to remain patient, persistent, and methodical in your approach, especially when dealing with complex backend issues.
