What to Verify Before Moving Production to a New Factory
Moving production to a new factory changes the conditions under which a product is manufactured. Materials, equipment, tooling, operators, subcontractors, and inspection methods may all differ, even when the product design and purchase specification remain unchanged.
A production transfer therefore requires evidence that the receiving factory can meet the agreed requirements at the intended production volume. The review should cover the information being transferred, the resources available, and the controls that will govern initial production.
Commercial decisions may already favor the move because of capacity, cost, location, or supply continuity. Quality verification helps establish the conditions under which that move can proceed.
The central question is whether the new factory can reproduce the approved product consistently under its actual production conditions. We recommend answering that question through defined approval stages before committing the full order volume.
Establish Exactly What Is Being Transferred
The scope of a factory transfer can be broader than the finished product suggests. A product may move with its existing tooling and material sources, or the receiving factory may propose different equipment, components, and manufacturing methods.
Begin by documenting which elements will remain the same and which will change. Include the product variants, production operations, material sources, tooling, packaging, and subcontracted work involved.
This exercise helps identify where previous evidence remains relevant and where new verification is needed. A test result for a particular material has limited relevance if the receiving factory proposes a different grade. A dimensional approval obtained using one mold needs review if production will use newly manufactured tooling.
We recommend recording each significant change alongside the characteristic it could affect, the evidence required, and the person responsible for approval.
The review should also address partial transfers. If one factory continues producing components while another takes over assembly, the handover creates additional questions about component acceptance, storage, identification, and responsibility for defects.
A clear transfer scope gives purchasing and quality teams a shared basis for planning the work.
Check the Completeness of the Product Requirements
Established suppliers often hold practical knowledge that has accumulated over many orders. Some of that knowledge may exist in revised drawings, email approvals, process adjustments, or instructions used only on the production floor.
Before a transfer, gather the current approved requirements into a controlled set of documents.
This should include the product specification, drawings, material requirements, bill of materials where applicable, packaging instructions, approved artwork, and inspection criteria. Each reference needs a revision number or another reliable way to identify its status.
Historical decisions also deserve review. An appearance concession granted for one shipment should be identified as a limited approval. A permanent design change should appear in the current specification.
We recommend including relevant quality history: recurring defects, customer complaints, previous corrective actions, and characteristics that have required close control.
For example, an assembly may have needed a particular alignment check after repeated fit problems. If that requirement remains buried in an old corrective-action report, the new factory could repeat the same issue.
A complete technical handover preserves the lessons already learned about the product. Ask the receiving factory to review the documents, identify ambiguities, and confirm how the requirements will be applied before sample production begins.
Verify the Actual Manufacturing Site and Production Responsibilities
Approval should relate to the facility and operations that will perform the work.
Confirm the production address, the processes carried out on site, and any activities assigned to subcontractors. Where a supplier operates several factories, identify which location will handle the order and where each significant process will take place.
An assessment should examine the capabilities relevant to the product. Supplier evaluation commonly considers experience, quality systems, capacity, and sample performance. The evidence needed depends on the work being assigned.
We recommend reviewing how incoming materials are controlled, how production instructions reach operators, how nonconforming goods are separated, and how defects are escalated.
A factory may have experience with the general product category while needing additional controls for a particular construction, finish, or tolerance. Review representative work and available production records to understand that distinction.
Subcontracted operations need defined requirements and oversight. Finishing, printing, coating, or specialized assembly may have a direct effect on the finished product.
The transfer record should identify who approves subcontractors, who verifies their output, and whether further subcontracting requires permission. This keeps the production arrangement visible throughout implementation.
Confirm Materials and Components Before Approving Substitutions
Material names can appear equivalent while leaving important characteristics unspecified.
A description such as steel, plastic, or fabric may omit grade, composition, thickness, construction, treatment, or performance requirements. The receiving factory needs enough detail to source and verify the intended input.
Compare proposed materials and components with the approved requirements. Identify any changes in manufacturer, grade, formulation, dimensions, finish, or construction that could affect the product.
Supporting evidence may include supplier documentation, measurements, relevant test results, and evaluation of representative samples. The method should address the characteristic being assessed. Visual similarity provides limited information about composition or long-term performance.
We recommend checking how the factory will distinguish approved materials from alternatives in receiving and storage. Material identification should remain connected to the production batches that use it.
Consider a hypothetical transfer involving an assembled household item. A replacement fastener matches the original dimensions, but its material and protective finish differ. Approval needs to consider the joint’s function and expected conditions of use.
Record substitutions explicitly. An agreed price and delivery date leave the technical suitability of a replacement to be established through the appropriate review.
Review Tooling, Equipment, and Measurement Methods
Existing tooling needs assessment before shipment and after installation at the receiving factory.
Record its identity, condition, maintenance history where available, and the associated fixtures or accessories needed for use. Confirm access to relevant setup information and establish responsibility for repairs or modifications.
After installation, verify that the equipment and tooling work together under the intended operating conditions. Transport, setup, maintenance, or different machine characteristics can affect the result.
New tooling requires its own approval evidence. Products made from separate cavities, stations, or fixtures may need representative checks where those differences could influence quality.
Measurement methods also need alignment. Two factories can report different results when they use different reference points, fixtures, product preparation, or measuring force.
We recommend agreeing the method, suitable equipment, measurement locations, and recording precision for characteristics that influence acceptance. Instruments should be calibrated or verified as appropriate to their use.
Where results approach a tolerance limit, investigate the measurement conditions before drawing conclusions about conformity.
The purpose of this review is to establish that the receiving factory can both produce the required characteristics and assess them reliably.
Evaluate Samples Made Under Representative Production Conditions
Sample approval is useful when the team understands how the samples were produced.
Ask whether the proposed production materials, tooling, equipment, operators, and subcontractors were used. Record any differences between sample preparation and the planned manufacturing process.
A sample made in a development workshop provides evidence about the sample itself. Additional verification may be needed before relying on it as evidence of routine production capability.
We recommend planning a pilot run appropriate to the product’s complexity and risk. The run should help assess repeatability, assembly consistency, process problems, and the controls needed before volume increases.
Review the output across relevant variants and production conditions. Where a characteristic is sensitive to a particular process, collect enough evidence to understand whether that process is operating consistently.
For example, a hypothetical factory transfer for an assembled storage product may produce an acceptable first unit. A pilot run could reveal that alignment varies as different operators perform the assembly. The follow-up should examine fixtures, work instructions, and verification at that operation.
Pilot approval should document the conditions that produced the accepted result. Keep the findings, corrective actions, and approval record connected to the next production stage.
Assess Capacity at the Required Quality Level
Quoted capacity needs to be considered alongside the resources and controls required for the actual product.
Review the production plan, equipment availability, staffing, material lead times, and any bottleneck operations. Check how the proposed order fits with existing commitments.
Output estimates should account for inspection, setup changes, maintenance, and the time needed to address nonconforming goods. A schedule based entirely on uninterrupted production may leave little room for the adjustments needed during a transfer.
We recommend reviewing pilot-run output together with the proportion of goods meeting requirements without rework. A production rate achieved through extensive sorting or repair may create additional pressure when order volume rises.
The first commercial order should have a realistic schedule for report review, corrective work, and verification before dispatch.
Where supply continuity matters, plan the transition between old and new production carefully. Consider available inventory, tooling availability, and the practical ability to continue production while remaining questions are resolved.
The appropriate arrangement depends on commercial conditions and product risk. The decision should make the consequences of a delayed approval visible before the original production capacity is released.
Review Packaging, Identification, and Existing Approval Evidence
A factory transfer should include the complete saleable product and its packaging.
Verify carton construction, internal protection, accessories, instructions, labels, artwork, assortment, and pack quantities against the approved requirements. Confirm that the factory has access to the current files and understands how variants are identified.
Where packaging materials or construction change, review whether additional performance verification is needed for the intended handling and distribution conditions.
Product and batch identification also need attention. Goods from the original and receiving factories may enter inventory during the same period. Records should allow relevant production and shipment references to be retrieved if a quality issue occurs.
We recommend reviewing existing test reports and approval documents for their relevance to the transferred product. Check the model, materials, components, construction, and manufacturing details described in the evidence.
The significance of a site change depends on the applicable customer requirements, product rules, and certification arrangements. Obtain appropriate technical review where approval conditions may be affected. Document the basis for retaining existing evidence and identify any additional testing or authorization required.
This review helps keep the information supporting product approval connected to the goods that will actually be supplied.
Agree the Inspection Plan Before the First Commercial Order
The receiving factory needs clear inspection instructions before production begins.
Agree the characteristics to check, the methods to use, the defect classifications, the sampling arrangements where applicable, and the acceptance criteria. Include product-specific examples for conditions that require interpretation.
Initial production may justify additional attention to risks identified during the transfer review. Each additional check should have a defined purpose and a review point.
| Transfer concern | Verification to consider |
|---|---|
| A new material source | Material identification, supporting documentation, and relevant tests |
| Relocated or replacement tooling | Setup checks and representative dimensional or functional evaluation |
| An unfamiliar assembly operation | Pilot-run review and checks during production |
| A different finishing subcontractor | Process review and verification of specified finish characteristics |
| Revised packaging | Construction, packing, identification, and appropriate performance checks |
A pre-production inspection can support checks of available materials, components, tools, and initial setup within an agreed scope.
A during production inspection can provide evidence about selected products and production conditions while manufacturing continues. Schedule it when relevant output is available and findings can still inform the remaining work.
Inspection reports should identify the goods examined, applicable specification, checks performed, results, and limitations. Unavailable tests or incomplete production should remain visible in the record.
Set Clear Conditions for Production Release and Transfer Closure
Before the transfer proceeds, agree who can approve each stage and what evidence they need.
We recommend separating approval to produce samples, approval for a pilot run, authorization for commercial production, and shipment release. Each decision relates to a different stage of readiness.
Maintain an open-issue record with responsible owners and target dates. Issues affecting safety, essential function, or mandatory requirements need appropriate resolution before the affected activity proceeds.
Where a limited deviation is permitted, record its scope, quantity, duration, and approving authority. Make clear whether it applies only to the initial batch or changes the product specification.
Transfer closure should also have defined criteria. Depending on the product, these could include completed corrective actions, acceptable production results, consistent application of inspection methods, and evidence from subsequent deliveries.
Review early warehouse observations and customer complaints alongside factory findings. A problem discovered after delivery may reveal a gap in packaging, instructions, or performance verification.
The first shipment is an opportunity to evaluate the transfer under commercial conditions. Continue reviewing the evidence until the agreed criteria for routine production have been met, then adjust temporary controls through a documented decision.
Before moving production, define the evidence needed to approve the receiving factory, the pilot run, and the first commercial order. Assign responsibility for resolving each open issue and connect every approval to the product and production conditions it covers.
ECQA can support the agreed verification plan through documented checks before and during production. Start by reviewing the proposed factory changes and identifying which product characteristics require fresh evidence.
