Perhaps make lists of

  - bug reports which never lead to any debug activity
    (no responsible person/team was found, or a seemingly person/team
    did not start to debug the report)

  - known regressions on release,

  - regressions that became known after release,

  - subsystems with notable backlogs of old bugs,

  - other categories?

Select typical cases from each categories, analyze what went wrong in
these cases, and try to identify practicable countermeasures.

Another approach:  Figure out areas where quality is exemplary and try
to draw conclusions for areas where quality is lacking.
