Go/no go

In general go/no go testing refers to a pass/fail test (or check) principle using two boundary conditions or a binary classification. The test is passed only when the Go condition is met and also the No go condition fails.

The test gives no information as to the degree of conformance to, or deviation from the boundary conditions. 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.
