Fagan Inspection

Fagan Inspection is a formal, structured code review process developed by Michael Fagan at IBM in 1976 that systematically identifies defects before testing. Using defined roles and checklists, Fagan inspections are far more effective at catching bugs than ad-hoc reviews; studies show 70–90% defect detection rate.
