   Some Observations:
•   Experience
with these methods has found them to be effective e in finding from 30%
to 70% of the logic design and coding errors in typical programs. They
are not, however, effective in detecting “high-level” design errors,
such as errors made in the requirements analysis process.  

•   Human
processes find only the “easy” errors (those that would be trivial to
find with computer-based testing) and the difficult, obscure, or tricky
errors can only be found by computer-based testing. 

•   Inspections/walkthroughs
and computer-based testing are complementary; error-detection
efficiency will suffer if one or the other is not present. 

•   These
processes are invaluable for testing modifications to programs. Because
modifying an existing program is a more error-prone process(in terms of
errors per statement written) than writing a new program.
