Like many “preventative” things, it can be hard to prove that problems would have occurred with less experienced/productive people because you only have one team and outcome in any situation. And there’s a lot of easy-sounding ways to “measure” quality that actually suck (e.g. “number of bug reports” says nothing about the kinds of bugs, and might encourage people to create micro-bugs to inflate numbers or mega-reports to make them smaller, depending).
