Quality Inspection
Part of Manufacturing and production oversight
Planning production checkpoints for a new supplier
Choose production checkpoints around decisions that become expensive to reverse, with evidence and owners agreed before the new supplier starts.
Plan a first production order around four release decisions: confirm materials before the full run, inspect a first-off unit before production continues, check a sample during the run, then review count and quality before dispatch. For each checkpoint, agree the pass criterion, evidence, named reviewer, response deadline and whether work may proceed, needs rework or must pause.
Start with the decisions that cannot wait
Start with the approved specification and mark the inputs or features that would make the product unacceptable if wrong. For a printed carton, these might be board grade, artwork version and colour; for a sewn item, fabric, measurements and seam construction.
Material confirmation — before the supplier commits to the full run. The owner is your named reviewer; the evidence is the supplier’s material confirmation checked against the approved specification, such as board grade or fabric.
First-off unit — before production continues. The owner is your named reviewer; the evidence is the first-off piece checked against the approved specification and reference sample, including relevant artwork, colour, measurements or seam construction.
In-process sample — during the run, early enough for correction to remain possible. The owner is your named reviewer; the evidence is the sample checked against the agreed criteria, with the supplier’s records of rework and segregation of rejected units available for review.
Pre-shipment count and quality review — before dispatch. The owner is your named reviewer; the evidence is the count and quality findings checked against the agreed variant quantities, specification and defect classifications.
Key Production Checkpoints for a New Supplier
- Material ConfirmationBefore full production run; verify board grade, fabric, artwork version and colour against approved specification.
- First-Off Unit InspectionBefore continuing production; check first-off piece against reference sample and specification including measurements and seam construction.
- In-Process Sample CheckDuring production run; early enough to allow correction; review sample against agreed criteria with supplier’s rework records available.
- Pre-Shipment Count & Quality ReviewBefore dispatch; confirm count matches variant quantities and quality meets defect classifications per specification.
Define what “pass” means
“Looks good” is not a release criterion. Record measurable dimensions or agreed tolerances where they matter, the approved reference sample, variant quantities and how defects will be classified. State whether each result permits the next step, requires rework or pauses production.
For each checkpoint, state whether the review is physical or remote; do not describe a remote image review as a physical inspection. Keep the evidence with the dated decision so both teams can see what was checked and what happens next.
Use one dated entry per checkpoint with these fields: checkpoint and timing, pass criterion, evidence, named owner, response deadline, and decision to proceed, rework or pause. Set the deadline before production starts, and book any independent inspector or test into the schedule.
If the first-off piece differs from the agreed sample, decide whether to correct it, change the approved specification or stop. Route any specification change through the agreed approval process, including any price or date effect, and record the decision.
The finished plan should let both teams act on a problem early enough to choose a remedy. Keep the criteria and checkpoint rights in the order or contract, rather than relying on an informal approval.
Agree Before Production: Key Release Criteria
- Measurable dimensions or tolerances definedYes
- Approved reference sample confirmedYes
- Defect classification system in placeYes
- Named reviewer assigned for each checkpointYes
- Response deadline set before production startsYes
- Decision path defined: proceed, rework or pauseYes
How to Handle Specification Changes After First-Off Discrepancy
- Assess discrepancy against approved sampleDetermine if deviation is critical or minor.
- Decide on actionCorrect the unit, update the specification, or halt production.
- Route change through formal approval processInclude impact on price, delivery date, and contract terms.
- Record decision and update contractEnsure all parties have access to revised agreement.
