Phase Index can be calculated by the help of the following formula, where

Ei – the total number of errors uncovered during the ith step in the SE process

Si – number of serious errors

Mi – number of moderate errors

Ti – number of minor errors

PSi – product size at the ith step

ws, wm, wt – weighting factors for serious, moderate, and minor errors

► PIi = ws(Si/Ei) + wm(Mi/Ei) + wt(Ti/Ei)

► PIi = ws(Si/Ei) + wm(Mi/Mi) + wt(Ti/T)

► PIi = ws(Si/Ei) + wm(Mi/Mi) + wt(Ti/Ei)

► PIi = ws(Si/S) + wm(Mi/M) + wt(Ti/E)
