What's best for the developer should also be best for the QA tester-they're on the same team, after all! If one of them is unhappy, it's usually a sign that something's off with the product or the process. The key is to hear everyone out, get to the root of the problem, and find a solution that can be built into the process going forward. For example, if a QA tester feels like their feedback isn't being taken seriously, I'd create a space where both sides can share their perspectives and align on what's needed. Maybe that means setting clearer expectations during sprint planning or adding checkpoints for better communication. Once we figure out a fix, it's just about making it part of the routine.
