QC Parameters

A QC Parameter is a named thing your inspectors check. "Chest measurement." "Color match to approved sample." "Zipper functionality." Each one is a master record carrying the details of how it's checked and what's acceptable.

Parameters are the vocabulary of inspection. Every Parameter Readings row on a QC Inspection references a Parameter. Build the library carefully — sloppy parameters mean sloppy inspections.

What's on a Parameter

The fields that actually shape behavior:

Parameter Name — what inspectors will see and pick. Be specific. "Chest" is bad; "Chest width at armhole" is good.
Inspection Type — one of three: Measurement (record an actual number), Visual (visual check, pass/fail), Functional Test (perform an action). Drives how the App and Desk render the parameter on the inspection form.
Inspection Tool — the tool used to inspect (tape measure, AATCC grayscale, spectrometer). Free text. Useful for training and for auditors who ask how a measurement is taken.
Specification — the target value, written in human language. "520mm at base size M, ±10mm" or "Match to approved sample, no shade off."
Tolerance — the structured tolerance for measurement parameters. Used by GarmentFlow to decide pass/fail automatically when an actual value is entered.
Item Group — which Item Group this parameter applies to. A "Chest" parameter applies to tops; an "Inseam" parameter applies to pants. GarmentFlow filters parameter pickers by Item Group when building IQ Templates.
Operations — which operations this parameter is checked at. A "Seam strength" parameter is checked at Stitching; a "Wash colourfastness" parameter is checked at Wash.
Critical Parameter — the flag that biases an inspection toward Rejected when it fails. Reserve for the parameters where one fail means the garment can't ship.
Weightage — for the Overall Score calculation. A 30%-weightage Chest parameter contributes more than a 5%-weightage Hem opening parameter.
Minimum IQ Level — the IQ Template rank at which this parameter starts being mandatory. A parameter with Minimum IQ Level = Q3 is only checked when the inspection is at Q3 or better.
Is Active — disable parameters that are out of use; don't delete them.

How parameters become inspections

You don't pick parameters directly when starting an inspection. The flow:

A Tech Pack has an IQ Template attached (set on the Tech Pack's Design tab).
The IQ Template lists the parameters that apply at that template's rank.
When an inspection is opened against a Production Batch, GarmentFlow pulls the IQ Template from the linked Tech Pack and populates the Parameter Readings table with those parameters.

So the discipline of building a clean parameter library pays off every time a new Tech Pack is created — the right parameters are already there, ready to be grouped into a template.

A working example

Building parameters for a basic tee:

Chest width at armhole — Measurement, tolerance ±10mm, Critical, 25% weightage, Item Group = Tops, checked at Stitching.
Body length — Measurement, tolerance ±10mm, 15% weightage, Item Group = Tops, checked at Stitching.
Sleeve length — Measurement, tolerance ±5mm, 15% weightage, Item Group = Tops, checked at Stitching.
Seam construction — Visual, 20% weightage, Critical, Item Group = Tops, checked at Stitching.
Color match to approved sample — Visual, 15% weightage, Critical, Item Group = Tops, checked at Final.
Label placement — Visual, 5% weightage, Item Group = Tops, checked at Finishing.
Hangtag attached correctly — Functional Test, 5% weightage, Item Group = Tops, checked at Packing.

Seven parameters, three types, two Critical flags. That's a complete enough library for a basic tee inspection. Add more as patterns emerge.

What to do next

Once parameters exist, bundle them into IQ Templates so they can be applied to Tech Packs.
