[SystemSafety] Request for links to papers about software defect densities

[Steve Tockey]

Along these same lines, does anyone have any reliable data on defect re-injection rates? Specifically, I remember hearing that on average for every 8 defects that are fixed, a new defect is injected as a result of that fix.

Does anybody have a pointer to reliable data along these lines?


Thanks,

Colleagues

I would be grateful for links or references to peer-reviewed papers that contain experimental or empirical evidence about software defect densities. I know of work over 30 years ago and it would be useful to have data that is more recent.

Thanks for any help you can give

Martyn
