Question: Basically my question can be divided into two parts.
1. How to manage cases or scenarios which are not required to be worked on, or does not really fall into the category of requirements? Should there be another platform where all such cases are mentioned area-wise? and the person who run into that issue again, check that area first instead of investigating & reporting it.
2. We can have obsolete cases and known bugs, which we agree upon, that no further development will be done. How to manage those cases?
Example: I recently found a bug and created a task for it,but it was closed later on by test lead on client side. The reason for closing the task was the end-user is not being affected by the issue thus there's no development needed. Now what's the best approach to handle this scenario, so no other person reports the same issue again in future and invest their time on it.
