Measure of how the system/individual performs its functions in a given environment (e.g., number of targets detected, reaction time, number of targets nominated, susceptibility of deception, task completion time.) It is closely related to inherent parameters (physical and structural) but measures attributes of system behavior. See also: measure of effectiveness. [DIS; IEEE 1278.3]
Ngumlinganiselo wokuba inkqubo/umntu uwenza njani umsebenzi wakhe kwindawo ayinikiweyo (umz., inani lokujoliswe kuko elifunyenweyo, iqesha lentshukumo, inani elikhethiweyo lokujoliswe kuko, ukuthabatheka okuqhathayo, ixesha lokugqiba umsebenzi). Unxulumene kakhulu nobuninzi obungatshintshiyo belifa (eliphathekayo nelisisakhiwo) kodwa kudwa kulinganisela okubalelwa ekuzipahtheni kwenkqubo. Jonga: umlinganiselo wempembelelo. [DIS; IEEE 1278.3]
