I think my boss give us a good opinion. Why need we a QA test team?
The QA team does not only discover the bug from SW/HW.
More important concept, More important concept, what reason causes this issue after testing this issue.
Then it can reduce SW/HW debugging time.
Now , we often hear the test link. We only see the pass/failed item of testing.
Can we get more information for debugging from these test case?
