Abstract: The authors explain how to perform software inspections to locate defects. They present metrics for inspection and examples of its effectiveness. The authors contend, on the basis of their experiences and those reported in the literature, that inspections can detect and eliminate faults more cheaply than testing.
Inspection 4 to 7 times faster than testing The average cost of finding an error using code inspections is 3.5 staff hours compared to 15-25 hours to find each error through testing
