Oi

Number of opportunities per unit for the ith component

ObsDi

Observed number of defects for the ith component

Shifti

Shift factor for the ith component

BU

AdjUi

=

Ci * BU

Adjusted number of units for the ith component
Note: If complexity is not used, AdjUi = ObsUi

AdjDi

=

Adjusted number of defects for the ith component
Note: If complexity is not used, AdjDi = ObsDi

AdjTOi

=

Note: If complexity is not used, AdjTOi = ObsUiOi

DPOi

=

when 0 < defects < total opportunities

=

when defects = 0, based on a 100% upper bound for DPOi

=

DPMOi

=

DPOi * 106

YTPi

(1 - DPOi)Oi

Throughput yield for the  ith component

YRTi

=

(YTPi)Ci

Rolled throughput yield for the ith component
Note: If complexity is not used, YRTi = YTPi

TD

=

S (AdjDi)

Adjusted total defects

TDPO

=

TDPMO

=

TDPO * 106

Total defects per million opportunity

TShift

=
