\label{tab:scenar2}Simulated QA costs, with defect prediction used
Phase 1.Development 2.Testing 3.Post-release
Number of defects fixed \(H_{phase}^{\prime}{}\) 525 188 125
QA cost per one defect \(C_{defect}\) x 2.775x 2.775x
QA cost per phase \(C_{phase}^{\prime}{}=H_{phase}^{\prime}{}\times C_{defect}\) 524x 522x 347x
