Answer:
Measures of Effectiveness
Explanation:

MOE actually measures the probability that a system will perform as required and perform as expected.
FOr MOE to be effective as an operational tester, the following characteristics must be available; testable, complete, simple, quantitatively measurable and easily measurable.
Therefore in order to determine whether a system meets its operational performance parameters Measures of Effectiveness must be employed.
