To be relevant, indicators need to correctly express the intention of the associated performance objective. Since indicators support objectives, they should be defined having a specific performance objective in mind.
Indicators are not often directly measured. They are calculated from supporting metrics according to clearly defined formulas, e.g. cost-per-flight-indicator equal Sum(cost)/Sum(flights). Performance measurement is therefore done through the collection of data for the supporting metrics. (same source)
