What is a Performance Model?
A performance model is a mathematical framework used to assess the
validity of performance data (an overlooked necessity)
data + model = information
1 Select performance metrics as inputs: λ, R, S, Q, . . .
2 Model is a relationship between those metrics: Q = λ R
3 Model outputs are calculated metrics
4 Compare calculated metrics with (other) measured metrics
5 Repeat until satisfied
Can then project metric values into circumstances that are not
measured or not measureable
