Have you been measuring how many defects you find at unit testing and system testing per KLOC and how much may cost to fix them?
I can find some information like:
with code reviews + unit testing one can find up to 70% of the defects.
Other studies say that the cost of finding and fixing a defect at unit testing is $428 and at system testing is $1045.
Do you know more benchmarks per industry type ?
What is your experience ?
Thanks in advance
