Any open source project that wants quality has a defect tracking system
and uses it well. Bugzilla is popular (www.bugzilla.org). Every
SourceForge project (and there are lots of them) has a bug tracking
systems built into the SourceForge platform. Other choices are available.
The examples of large-scale projects such as Mozilla that see increasing
product quality over time show that the time-proven technique of tracking
defects stil works.

Actually, I find this useful for regressions. If this analysis can expose
the problems in the development process which allowed the defect to be
introduced, the process can be modified to prevent similar process
failures.

We are saying the same thing, but the important test cases are those near
maxima, minima and discontinuities. This applies to both the external and
the internal variables.
