Your main factory is running late. Purchasing calls the second supplier that passed a trial last year, only to learn that its material source changed and the old tooling is not available. A successful trial is historical evidence, not a current executable supply plan. Review the backup while there is still time to resolve gaps, rather than discovering them during an emergency.
This scenario and the records below are fictional editorial illustrations. They are not customer transactions, a technical standard or legal advice. Qualified specialists must define product acceptance and contractual terms. There is no universal review interval or guarantee of reserved capacity.
Reopen the evidence that can become stale
Start with the last approved product revision, manufacturing site, material baseline and trial findings. Ask the backup to confirm what remains unchanged and identify differences. Include subcontracted operations where relevant. A salesperson's statement that the product is still available is not evidence that the approved process can be repeated.
Have the quality specialist assess the age and condition of the reference sample and whether it still represents the current specification. Time alone does not make a sample invalid, but neither does an old approval make it suitable for a revised product. Record which comparisons or tests need refreshing and who can accept them.
QIMA's manufacturing-audit scope covers production capability and quality-management assessment. This is a provider's service description, not a promise that an audit secures future output. Use it as context for selecting appropriate evidence, not as a universal readiness certificate.
Check access, not just ownership, of tooling
Ask where the required tools are, their condition, whether they can be used for your product and what preparation is necessary. A buyer-owned tool at another factory may not be accessible when the backup needs it. Do not treat an asset list as confirmation of possession, compatibility or permission to use it.
The tooling access guide handles the separate recovery and access problem. Here the readiness file should record the dependency, responsible person and unresolved timing, rather than repeat a tooling-return procedure. If tooling availability is uncertain, the backup's lead time is uncertain too.
Obtain a lead time that can actually be executed
Request a dated capacity statement for the proposed quantity and production window. Separate material procurement, tool preparation, production, checks and dispatch readiness. Ask what other commitments constrain that window and what event would make the estimate lapse. A catalogue lead time is not a confirmed production slot.
Agree how the supplier will report a changed constraint before activation. If you want a paid capacity commitment, negotiate its scope separately. Do not describe an informal availability reply as a guaranteed reservation, or imply that a payment service reserves factory capacity.
Keep a bounded readiness card
| Field | Current evidence and decision |
|---|---|
| Approved baseline | Revision, site, materials and unresolved differences |
| Reference sample | Custodian, condition and specialist's refresh decision |
| Tooling | Actual access, readiness and preparation dependency |
| Capacity | Dated window, quantity, constraints and expiry event |
| Activation | Trigger, authorised decision-maker and permitted pilot |
| Refresh | Next review event and owner of change reporting |
This is a proposed purchasing record, not an industry-mandated form. Set review timing around actual product changes, inactivity and supply risk. There is no prescribed number of months after which every backup must repeat a trial.
Activate by decision, not by panic
For the fictional buyer, a main-factory delay triggers a review, not an automatic full transfer. Purchasing verifies whether the backup can satisfy the current baseline. The technical reviewer closes material questions, and the authorised buyer approves only the scope supported by evidence. That might be a limited pilot, further verification or no order.
The two-supplier trial guide covers initial comparison. Do not reopen that comparison without a reason; this task concerns the decay of an already tested backup's readiness. The site-change guide addresses a distinct production-location change. A dormant supplier can lose readiness even without moving sites.
Article 35 of the official CISG text concerns contractual conformity. Counsel must check applicability and the actual agreement. Current technical approval does not itself create a capacity commitment or excuse obligations to the main supplier.
Keep the payment decision downstream
Before a new purchase, connect the approved pilot scope to the accepted order and its payment milestones. Resolve commitments to the main factory separately; activating a backup does not automatically cancel them. Keep the readiness evidence dated so the next buyer can see what was known at approval.
Use pay an invoice to ask A2vanta about an approved supplier payment before funding. Factory qualification, available capacity and the decision to switch remain with the buyer, supplier and qualified specialists.
