As an example, the differences between 75mm and 90mm tank guns in range, accuracy, and penetrating power against enemy tanks have a significant bearing on measurements of system effectiveness but are irrelevant to evaluations of their operational readiness and availability.<\/p>\n<p>The characteristic discussed in the preceding paragraph can be identified by the term &#8220;system design adequacy.&#8221; System design adequacy is the probability that a system will successfully accomplish its mission, given that the system is operating within design specifications.<\/p>\n<p>The design may include alternative modes of operation, which are equivalent to built-in automatic repair, usually with allowable degradation in performance. These alternative modes of operation are, of course included in the definition of system design adequacy. The probability itself is a function of such variables as system accuracy under the conditions of use, the mission to be accomplished, the design limits, system inputs, and the influence of the operator.<\/p>\n<p>&nbsp;<\/p>\n<p>References:<\/p>\n<p style=\"padding-left: 30px;\">1.
