Combining Performance Metrics
Okay I need some help. Im trying to figure out my performance metrics, I havent been in college in a couple years & not for sure if Im doing this correct.

Say an employee has a benchmark of 90% or better in a metric he exceeds his goal at 91.39%, next his benchmark is 15% or below, he also exceeds that metric @ 13.07. Then his next benchmark is 4.5% or below, he exceeds at 3.8%
His performance metrc must be at 91% overall, his performance metric is added from all e metrics above.

SO he was at 91.39 out of 90%, must stay below 15% he was at 13.07, then 4.5 or below, he was at 3.8.
I have a performance metric of 108% is that correct? Please help I want to make sure I get paid correctly!

I hope this makes sense! Thanks

91.39 out of 90 is $\frac{91.39}{90}= 1.015$ (to three decimal places), 13.07 out of 15, where the goal is to be less than 15 is $\frac{15}{13.07}= 1.148$. 3.8 out of 4.5, where the goal is to be less than 4.5 is $\frac{4.5}{3.8}= 1.184$. Now, the question is how are those to be combined? Assuming they are all "weighted" equally, their average is $\frac{1.015+ 1.148+ 1.184}{3}= 1.115$ or 111.5%
