CONTROL PATH / 01
One controlled plan, several separate evidence events.
A useful quality control plan does not collapse sample approval, process checks, lot inspection and buyer release into one “QC passed” label. It gives each event a defined question, controlling reference, evidence owner, close-out rule and permitted next action.
Define the product, order, process scope and decision authority
Name the legal seller, actual production site, product or SKU, purchase order, quantities, destination, applicable revision and processes covered. Identify the buyer representative who can approve the plan, accept a deviation, order containment, require reinspection and release the named next stage.
ISO 10005:2018 provides guidance for establishing, reviewing, accepting, applying and revising quality plans for processes, products, services, projects or contracts. It is guidance, not a universal set of product requirements.
If the plan does not state what evidence is needed for a specific decision, it becomes a list of activities rather than a control record.
Lock the approved requirements and version hierarchy
List the controlling drawing, specification, bill of materials, approved sample, test method, packaging artwork, labelling requirement and purchase-order revision. State which document controls if references conflict and how the factory acknowledges a new revision.
ISO 10007:2017 provides lifecycle guidance for configuration management. Use a visible change log so a material, component, process, tooling, factory, critical sub-supplier, artwork or method cannot silently replace the approved baseline.
Map each risk to an observable production checkpoint
Define checkpoints for the risks that matter to this product and order: incoming critical materials, tooling or setup, first production output, critical or special processes, in-process work, lab or functional tests, packing and the final shipment lot. Give each checkpoint an observable trigger rather than a vague calendar date or percentage complete.
State which work may continue while a check is open and which work is a hold point. A sample approval, first-piece review, during-production inspection and pre-shipment inspection answer different questions and should retain separate results.
Assign the method, equipment, competence and evidence record
For every checkpoint, state the characteristic or requirement, method, tolerance or acceptance rule, equipment and calibration expectation, required competence, evidence format, owner and retention location. Record “not observed” or “not testable” instead of converting missing access into a pass.
ISO/IEC 17020:2026 specifies requirements for the competence, impartiality and consistent operation of bodies performing inspection. Where an independent inspection body is used, verify that its actual scope, method, access and report cover the buyer’s defined question.
Define the lot, sample frame and sampling decision
Identify the lot or population, locations, unit states, selection method, sample size, defect or characteristic categories, acceptance rule and treatment of excluded, unavailable or reworked units. Keep destructive tests, process observations and unit sampling separate when they answer different questions.
A sampling plan answers a defined lot question; it is not a 100% inspection or a quality guarantee. ISO 2859-1:2026 describes AQL-indexed acceptance-sampling schemes for lot-by-lot inspection. Use the applicable licensed standard and qualified product input rather than copying a fixed AQL or sample size from a generic checklist.
Separate containment, correction and corrective action
Record the unmet requirement, objective evidence, affected product or process, quantity and locations, immediate containment, disposition authority, owner and due date. Preserve disputed findings and the factory’s response as separate fields.
Correction removes a detected nonconformity; corrective action addresses its cause to prevent recurrence. The ISO 9001 Auditing Practices Group’s official nonconformity review and closing guidance distinguishes those concepts. The APG paper is informative guidance, not a new requirement or product-specific acceptance rule.
Control the revised baseline, corrected units and close-out evidence
Before accepting a change, identify the reason, affected requirements, units and documents, risk review, buyer authority and effective point. Keep corrected or reworked units traceable to the original finding and prevent uncontrolled mixing with untouched production.
Define whether close-out needs a document review, repeated measurement, new test, targeted reinspection, broader sample or full checkpoint. A supplier’s photo or promise can support a record but does not automatically close the finding that triggered the decision.
Put the proposed change, buyer decision and effective revision into a separate control record →
Record a buyer-owned release for one named stage
The authorised buyer reviewer should sign or record the plan version, evidence reviewed, open exceptions, conditions, affected quantities and the exact next stage allowed. A release to continue production is not automatically release to ship, pay the balance, accept contractual delivery or confirm destination-market compliance.
When evidence is missing or criteria are not met, use a visible hold, correction or reinspection state. Do not let an inspector, supplier or platform status silently replace the buyer authority defined in the plan.
CONTROLLED PLAN / 02
Minimum fields for a reviewable supplier quality control plan
| Plan field | Define before production | Record during execution | Hold when |
|---|---|---|---|
| Identity and scope | Seller, site, product/SKU, order, quantity, destination and covered processes | Actual site, product, stage and access limits | The observed work cannot be tied to the named order or site |
| Requirement and version | Controlling specification, drawing, sample, method and hierarchy | Exact revision used and any conflict or change request | Production uses an unapproved or ambiguous reference |
| Checkpoint and trigger | Risk, observable milestone, hold/witness rule and permitted work | Date, actual state, populations and unavailable evidence | The required risk or process cannot be observed in time |
| Method and evidence | Characteristic, method, tolerance, equipment, competence and record format | Results, equipment, operator/inspector and source files | A critical check is skipped, substituted or unsupported |
| Sampling and scope | Lot, frame, selection, sample size, categories and acceptance rule | Units selected, locations, exclusions and actual sample | The sample cannot be traced to the defined population |
| Nonconformity control | Classification, containment, disposition and escalation authority | Requirement, evidence, affected units, owner and due date | Affected work is not identified or contained |
| Correction and cause | Correction, corrective-action and close-out expectations | Corrected-work identity, cause evidence and effectiveness check | A promise replaces required correction or verification |
| Buyer release | Authorised reviewer, decision states and next hold point | Dated evidence version, exceptions, conditions and exact action allowed | No authorised person owns the next-stage decision |
DECISION STATES / 03
Keep every checkpoint in one explicit state
| State | Minimum record | Permitted next action |
|---|---|---|
| Not ready | Missing baseline, trigger, access, method or responsible party identified | Resolve the named gap before production or inspection proceeds |
| Plan approved | Plan version, scope, checkpoints, authority and supplier acknowledgement recorded | Begin only the work authorised by the approved plan |
| Check open | Checkpoint started; results or buyer review remain incomplete | Continue only work expressly allowed while the check is open |
| Correction required | Nonconformity, affected work, containment, correction and owner recorded | Correct the named issue; keep affected work controlled |
| Reinspect | Corrected-work identity, method, sample/scope and close-out criteria approved | Repeat the named evidence event before release resumes |
| Buyer release | Authorised reviewer, date, evidence version, exceptions and exact next stage recorded | Proceed only to the named stage and next hold point |
| Hold | Reason, affected scope, containment and escalation owner visible | Do not proceed until a new buyer-owned decision is recorded |
METHOD / 04
How this checklist was prepared
Currawong Web’s China-side verification desk reviewed the official sources below on 30 July 2026. ISO 10005 supports the quality-plan lifecycle; ISO 10007 supports controlled configurations and changes; ISO/IEC 17020 supports inspection competence, impartiality and consistency; ISO 2859-1 defines the lot-by-lot acceptance-sampling boundary; the ISO 9001 Auditing Practices Group paper supports the distinction among a nonconformity, correction and corrective action.
The eight-control workflow, plan table and decision states are our evidence-control synthesis. We did not review any reader’s supplier, factory, product, process, order, sample frame, contract, technical file or destination-market rules. This is general evidence-organising guidance, not a quality plan for a specific product, inspection instruction, certification, compliance assessment, legal advice, supplier approval, production release or quality guarantee.

COMMON QUESTIONS / 06
Keep the plan inside its defined evidence boundary
- Is a supplier’s own QC checklist enough?
- It can be an input. The buyer still needs to confirm that the current scope, revisions, checkpoints, methods, exception rules and release authority answer this order’s risks.
- Should I use one fixed AQL for every product?
- No universal value is supplied here. Define the lot question, risks, contractual rules and applicable standard with qualified input; keep destructive tests, critical characteristics and regulatory requirements outside a copied generic number.
- Is correction the same as corrective action?
- No. Correction addresses the detected nonconformity. Corrective action addresses its cause to reduce recurrence. The plan should show when each is required and how close-out will be verified.
- Does a passed checkpoint release the shipment?
- Only if an authorised buyer record expressly releases that named stage and every separate shipment-release condition is met. A first-piece or in-process result does not automatically release the final lot.
- Does this replace destination-market compliance work?
- No. Product safety, labelling, testing, technical documentation, import, social, environmental and worker-safety obligations need their own applicable criteria and qualified review.
