TTS GLOBAL
Do not read only PASS or FAIL
Check available quantity, readiness, sampling, missing files and site limitations first. The same verdict can carry different risk under different conditions.
Trace the evidence
Each key defect needs description, count, class, location and photos. Measurements and tests need method, sample and result.
Turn the report into action
Separate immediate correction, clarification, accepted deviation and follow-up points for the next lot.
What to check in the evidence
Define the lot
Identify the order, models, colours, sizes and quantities presented for inspection. Record finished, packed and inaccessible quantities separately.
Why it matters
A result for the available goods cannot silently cover unfinished units or a different production batch.
Agree the sampling plan
Specify the sampling standard and edition, inspection level, normal/tightened/reduced status where applicable, and acceptance criteria by defect class.
Why it matters
Sample size and acceptance/rejection numbers come from the selected plan. AQL alone does not define the complete inspection.
Classify and count consistently
Agree examples of critical, major and minor defects. Record the unit, defect location and whether the counting basis is nonconforming units or nonconformities.
Why it matters
The same observation should not be classified differently by the factory, inspector and buyer. Safety issues also need their own escalation rule.
Keep checks separate
Distinguish sampled workmanship results, measurement results, functional checks, packing conformity and incomplete tests.
Why it matters
An acceptable workmanship count does not cancel a failed safety check, wrong barcode or missing mandatory label.
An illustrative scenario
A dimensional pattern needs more than a defect total.
Illustrative example: an apparel order contains several sizes. The sampled garments have acceptable sewing, but measurements from one size repeatedly fall outside the approved tolerance. The report should identify that size, the points measured, actual readings and the specification limits. The buyer can then ask the factory to isolate and recheck the affected size, instead of accepting the entire order because the overall appearance looks good.
Prepare these before the next step
- Purchase order, item quantities and factory contact.
- Specification, approved sample or reference photos.
- Packing artwork, required checks, acceptance criteria and shipment date.
Use the report to discuss defects with the supplier, request rework, seek further evidence or decide on shipment release. The buyer retains the commercial acceptance decision.
