How to stop endless product sample revisions
Agree what each sample must prove before the factory makes it. Record changes and results in an iteration log, resolve conflicting feedback internally, and authorise further work only when it answers a defined question. Approve, revise, pause or stop against agreed criteria. Ask Cambridge China Bridge to coordinate this with its staff in China.
Agree what the next sample must prove
Write a sample brief stating the question to answer, the features being assessed, the checking method and the acceptance criteria. A fit sample might test whether a closure works with the intended contents while leaving colour undecided. Identify what remains provisional so reviewers do not reject a development sample for features it was never intended to prove.
Name the buyer who can approve the brief and agree a review date, spending boundary and stopping conditions with the factory. Use our product specification guide for the underlying requirements and MOQ and sampling guide for sampling arrangements. Keep this round's objectives separate from the full product specification.
Keep an iteration log that preserves decisions
Give each sample a distinct version label and use it on the physical sample, photographs, drawings and feedback. Keep earlier entries rather than overwriting them. Record what the factory actually changed, including any material or process changes, so a better result can be traced to its cause.
Use the log below as a working template. Each unresolved issue should have an owner, a proposed action and evidence needed for closure. Keep passed features visible and check them again when a related change could disturb them.
| Field | What to record |
|---|---|
| Sample identity | Version label, date received and linked drawings |
| Objective | Question being tested and agreed acceptance criteria |
| Requested and actual changes | Buyer instruction, factory response and any deviation |
| Result | Observations, measurements, photographs and test conditions |
| Open issues | Required correction, owner and evidence needed |
| Decision | Approve, revise, pause or stop; approver and reason |
Send consolidated feedback the factory can act on
Collect comments from design, buying and intended users before sending the factory an approved feedback document. Separate failures against the brief from preferences and new requests. Resolve contradictory instructions internally. Replace 'make it better' with the observed problem, the desired outcome and how the revised sample will be checked.
Ask the factory to confirm its proposed correction and identify any effect on features already accepted, cost or production method before work starts. If a request changes the intended product, reopen the brief and agree its consequences. Do not hide a redesign inside a correction list or let scattered messages become competing instructions.
Make a stopping decision after every review
Compare the sample with the agreed objectives and record whether the evidence supports approval, a targeted revision, a pause or stopping development. Authorise another round only when the factory has a credible change to try and the result will answer a remaining question. If a defect returns, ask what caused it and why the proposed correction should work.
Pause when feedback conflicts, requirements remain undecided or the next step needs a fresh budget decision. Stop when the factory cannot explain a workable route, essential objectives remain unmet or the expected benefit no longer justifies further spending. Past sample costs are not a reason to continue. Record the decision and tell the factory whether further work is authorised.
Close development with a defined handover
When objectives are met, record exactly which sample version and documents are approved, the purpose of that approval and any excluded features. Keep optional improvements in a separate future-development list. Reopen a closed feature only for a stated reason, with its impact agreed, rather than treating every new preference as another sample correction.
Development approval should lead to a separate production decision. Our guide to making bulk production match the sample covers the golden sample, bulk-material approval and production checks. Cambridge China Bridge's staff in China can coordinate factory feedback and sample records while the named buyer retains the approval and stopping decisions.
Frequently asked questions
How many sample revisions should I allow?
Agree a spending boundary and review points before work starts. Continue only when a defined change can resolve an open issue and the expected benefit justifies the extra work.
What should a sample iteration log include?
Record sample identity, objectives, requested and actual changes, results, open issues, action owners and the approval or stopping decision. Link photographs and drawings to the relevant version.
How do I handle conflicting sample feedback?
Resolve disagreements within your team before sending approved feedback. Separate failures against the brief from preferences, and have the named approver decide which changes the factory should make.
When should I stop sample development?
Stop when essential objectives remain unmet without a credible correction, or further spending no longer makes sense. Pause if decisions or evidence are missing. Record the reason and withdraw authorisation for further work.
