Purpose
State whether the sample is for product direction, appearance, function, packaging, photography or production approval.
SAMPLE & APPROVAL PROCESS
Give prototypes, color samples, packed samples and pre-production references a defined purpose so approvals remain traceable when the project changes.
A physical unit can answer important questions, but it should be connected to written product, packaging and approval information before it becomes a production reference.
State whether the sample is for product direction, appearance, function, packaging, photography or production approval.
Record shape, panel, base, controls, accessories, packaging and revision so feedback cannot drift to a different version.
Capture observations, approved points, rejected points, changes and remaining questions with a named reviewer and date.

Feedback such as brighter, better fit or premium packaging is difficult to execute until it is linked to a location, reference, observable outcome and decision owner.
When a change is accepted, issue a new revision and state whether earlier approvals still apply.
Define the decision the sample must support and the evidence needed to make it.
Identify the complete product, contents, packaging and files represented by the sample.
Observe under agreed conditions and record evidence, comments, owner and due date.
Approve, reject or revise; then identify which physical and digital references govern the next stage.
The exact checklist depends on the sample purpose, but these inputs keep most reviews anchored to the real configuration.
There is no universal number. The rounds depend on the decisions, changes and risk remaining. A new material, pack or control change may require a new sample even when the shape is unchanged.
Photos can support a review but may not represent scale, fit, surface condition, operation, packing protection or lighting behavior. Decide what evidence is adequate for each approval.
It is a specifically identified approved reference used with written requirements. Its status, storage, validity and relationship to later revisions should be controlled.
Share the product direction, market, sample purpose, current files, required observations and the people responsible for approval.
