What We Have Learned About Fighting Defects

Forrest Shull et al
Presented at Metrics 2002

Findings relevant to IfSQ Standards:

Debugging and associated rework takes about 50% of the time spent in a typical software development cycle
Construction errors detected during system testing cost 10 times more to fix than in the construction phase and 10-25 times more to fix when detected post-release
