This checklist covers what to verify at the pre-production stage and what to document so the factory and the buyer are aligned before a single production unit is made.
What a pre-production inspection covers
The PPI checks whether the factory is actually ready to run the order correctly. It looks at inputs (materials, components, samples, tooling) rather than outputs. By the time finished goods are available to inspect, the cost of a mistake is already baked in.
A PPI typically involves the QC team, production supervisor and, where required, the buyer representative. Document findings and obtain the approvals required by the control plan before starting production.
Raw materials and components
Verify that all materials required for this order have arrived and match the approved specifications:
- Check material descriptions, colors, grades, and weights against the approved spec or purchase order
- Verify supplier labels and certificates where required: fabric composition, country of origin, chemical compliance
- Inspect for visible defects: wrong shade, damaged rolls, mixed materials from different batches
- Confirm quantities are sufficient for the full order, including cutting loss allowance
Do not rely on the supplier's delivery note. Inspect the physical goods against the written specification.
Approved samples and production standards
Confirm that current approved references are available where the work is done. Depending on the product, these can include:
- Approved pre-production or golden sample, signed off by the buyer
- Counter sample or sealed sample used for final approval reference
- Approved artwork files or print proofs for any printed components
- Spec sheet with key measurements, tolerances, and workmanship requirements
If a required reference is missing, hold the affected work until an authorized decision resolves it. Not every product requires a physical golden sample; use the approved reference method for the order.
Production team readiness
Check that the workers assigned to this order understand the product and the quality requirements:
- Have the line workers been briefed on critical quality points for this style?
- Is there a workmanship standard or defect guide visible at each station?
- Have new techniques or unfamiliar operations been practiced before the run starts?
- Is the correct SOP posted or available at each production station?
Confirm that operators understand the new product before the run. A short review can prevent avoidable sorting and rework; it is not a guarantee that the process will produce conforming output.
Equipment and tooling checks
Verify that equipment is available, correctly set up and suitable for the work. Check calibration or verification status for measuring instruments; not every production tool requires calibration.
- Confirm the correct needles, threads, or blades are fitted and match the spec
- Check that machinery settings (stitch density, tension, temperature) match the approved parameters
- Verify that any measuring tools or gauges used for quality checks are calibrated and within tolerance
- Inspect tooling for wear: a worn cutting die or bent needle will produce consistent defects across the entire run
Documentation to complete before production starts
The pre-production inspection must produce a written record before the line is authorized to start:
- Pre-production inspection report: findings, photos, and sign-off
- List of any open items: issues found during the PPI that require resolution before or during the run
- Production hold notice: if any critical issue was found, this document formally stops the line until the issue is resolved
- Authorization: record the people required by the control plan or customer agreement to approve startup
A verbal 'it looks fine' is not a record. If a post-shipment dispute refers back to this point in the process, you need a document, not a memory.
How to handle a pre-production hold
If the PPI finds a problem that cannot be resolved before production starts (wrong material, missing approved sample, equipment out of tolerance), issue a formal hold.
The hold notice specifies the exact issue, who is responsible for resolving it, and the target resolution date. Production does not start until the hold is cleared and re-signed.
Document the hold, resolve its cause and obtain the required written release. Early correction can avoid rework across the order, but cost and timing depend on the specific issue.
Key takeaways
- Run the PPI before the line starts, not partway through the first batch.
- Verify raw materials against the approved specification, not just the supplier's delivery note.
- Confirm the approved references required for the product are available before production.
- Document findings and obtain the startup approvals required by the control plan.
- Keep open issues, hold decisions and release evidence in the same record.
