Whoever is giving your team heat about bug metrics needs to read about Goodhart's Law.
There's so many ways to influence number of bugs that it's pointless to measure anything that way. For example, do you make a single bug that lists 15 typos spread around, or 15 bugs (because after all, each typo is a different word and in a different part of the app). Do you accept vague but obviously real bugs while you try to collect enough info over time, or immediately close them as "cannot reproduce"? Is that a bug, or really a feature request?
