Rating Formula

[formula] \begin{align} \displaylines { KPI_{Value}\\ KPI_{MinReq} = 1\\ KPI_{Target} = 0 } \end{align} [/formula] [formula] KPI_{Rating} = 100 \times \frac {(KPI_{Value} - KPI_{MinReq})} {(KPI_{Target}-KPI_{MinReq})} [/formula]

Rating Example

KPI Value= 1
KPI MinReq= 1
KPI Target= 0
KPI Rating[formula]=KPI_{Rating} = 100 \times \frac {(KPI_{Value} - KPI_{MinReq})} {(KPI_{Target}-KPI_{MinReq})} = 100 \times \frac {(1 - 1)} {(0-1)} = 0[/formula]
