OEM sample approval should translate “this looks right” into a clear description of what the production order must deliver.
A prototype can have the right shape and feel while still using temporary materials, substitute components or unfinished packaging. Those open details belong in the approval record.
1. Establish what the sample represents
Ask the supplier which stage the sample represents: a shape study, a functional prototype or a sample intended to demonstrate the production finish.
Identify which decisions you expect to make from that particular version.
Recording that boundary makes it less likely that approval of one feature will be treated as approval of the entire product.
2. Consolidate revisions into one change list
Organize feedback before sending it. Requests such as “slightly smaller” or “improve the color” leave the result open to interpretation.
Give each change a specific location and an observable outcome.
| Field | What to record |
|---|---|
| Location | The affected part and an annotated photograph number |
| Current condition | The dimension, position or behavior observed |
| Requested result | A measurement, physical reference or defined action |
| Review method | A new sample, measurement or approval file |
| Outcome | Accepted, needs another review or on hold |
Record the features that must remain unchanged as well. When the next sample arrives, check both the requested revisions and the details approved previously.
Update the shared list whenever a requirement changes, and identify the version everyone should use.
3. Link the approved sample to a specification
Label the final reference sample with the product identifier, specification revision and approval date.
Agree which physical item represents the production target, who retains it and where it can be accessed for comparison.
Photographs are useful for identifying a feature, but lighting and displays can change perceived color. Agree the basis for final color decisions.
Where additional testing is needed, record the method and acceptance conditions separately from visual approval.
4. Review the product in its complete packaging
After reviewing individual components, assemble the product in the condition intended for sale.
Adding the instruction sheet may affect how a lid closes; protective material may contact an operating part. These questions become easier to assess with the complete set in hand.
5. Define the conditions for starting production
Bring the final specification, quantities, costs, payment terms, schedule and inspection scope into the order record.
Identify who approves the order and who communicates the instruction to start.
A subsequent material or component change should trigger a review of the affected requirements before work continues.
Prepare a brief with clear open decisions
Send product images, expected quantities, intended use, target timing and the current sample status.
If drawings are unavailable, distinguish essential requirements from details you would like to develop through discussion.
