QC categories

Each QC Test Item falls into one of the following categories:

Regulatory

A QC Item specifying a Test that must be performed due to requirements set by a regulator or government. Has a published reference document or standard.

Absolute

Defined in a standards document including a standard scale. May have a defined pass/fail threshold. As a user, I ought to be able to compare the results of different QC devices and see the same result.

Objective

Measurable in a quantitative way against a defined scale, but no standard threshold is agreed. There may be no formal spec or standard, but an agreed method is implied by or exists in the test definition. As a user, I ought to be able to compare the results of different QC devices if I configure the same thresholds.

Subjective

May be measurable but with only a medium degree of confidence. A failure threshold is not defined, or is very vague. May require human interpretation of results. As a user, I cannot expect different QC devices to report identical results.

Human-review only

Gold coloured cards are used for Tests that can only be carried out by human eyes or ears (Golden Eyes and Golden Ears) or where a human is required to fully interpret the results of an automated QC tool.
