Answer:

As a QA Engineer, I am well aware that sometimes there could be disagreements between the QA and development team regarding the severity of a bug. Here is how I would approach the situation:1. Understand the Issue:
I would begin by talking to both teams individually to understand the root cause of the disagreement. 2. Analyze the Bug Severity:
I would then analyze the bug severity in-depth by referring to industry-standard guidelines such as the Severity Level Definition provided by IEEE and the Bug Severity Guidelines published by Bugzilla. 3. Communicate the Findings:
Based on my analysis, I would communicate my findings to both the QA and development team. I would present my reasoning and share my insights and recommendations on how to resolve the issue. 4. Reaching an Agreement:
If both teams still disagree, I would escalate the issue to a project manager or team lead to help in reaching a conclusion. It’s important to seek input from different stakeholders, assessing business impact, and analyzing the potential harm of the bug.5. Continuous Improvement:
I would ensure that a mechanism is put in place to avoid such disagreements in the future. I believe that transparency, communication, and maintaining a common definition of “severity” are key to mutually beneficial agreements.In summary, resolving disagreements between QA and the development team requires thorough communication, in-depth analysis, and the willingness to seek guidance from other stakeholders. Seeking industry-standard guidelines and best practices are recommended to ensure a high-quality product is delivered. Citations:
