These tests can be used for [[statistical process control]] purposes. There are specific SPC tools that use parameter based measurements (e.g., P-charts) for determining the stability of a process.
== Uses ==
=== Engineering ===
In [[engineering]] the test is traditionally used only to check noncritical parameters where the manufacturing process is believed to be stable and well controlled, and the [[tolerance (engineering)|tolerance]]s are wide compared to the [[frequency distribution|distribution]] of the parameter.
For example, the preceding checks before a [[space shuttle]] liftoff have the [[flight controller]] performing a go/no go check on each of the vehicle's critical systems.
=== Psychology ===
In [[psychology]] Go/No-go tests are used to measure a participant's capacity for sustained [[attention]] and response control.
For example, a go/no-go test that requires a participant to perform an action given certain stimuli (e.g., press a button - '''Go''') and inhibit that action under a different set of stimuli (e.g., not press that same button - '''No-Go''').
=== Military ===
In the [[United States Army]], drills and proficiency evaluation rubrics are based on a GO/NO GO (pass/fail) system. Evaluations involving numerical scores (such as the Physical Fitness Test) convert raw scores to GO/NO GO based on cutoffs defined by the particular performance standard for that area. Within a given skills unit, the rubric often specifies GO/NO GO scoring for each individual item or concept a soldier is expected to be trained and evaluated on. Usually, a soldier must score GO (i.e. perform satisfactorily) on all sections of an evaluation in order to advance to the next phase of training, to pass the course, and/or to attain the particular qualification.
