In one study conducted at IBM (Jones, 1991), code inspection found 65% of the known coding errors and 25% of the known documentation errors, whereas testing found only 20% of the coding errors and none of the documentation errors. The code inspection process may be more effective than walkthroughs. One study (Fagan, 1976) found that code inspections resulted in code with 38% fewer failures, compared to code walkthroughs.
