===== Discussion =====

A Performance Measurement is the process used to obtain a value for a [[public:99_annexes:annex-b-terms-and-definitions:p:performance_measure|Performance Measure]]. It occurs under identified conditions and an identified [[public:99_annexes:annex-b-terms-and-definitions:w:workload|Workload]] so that its result can be interpreted and reproduced.

The process may use direct observation, counting, instrumentation, calculation, or a model consistent with the applicable measurement method.
