Case boundary
This is a process case, not a fictional customer result.
The example below shows the evidence chain a buyer can use for a custom box, insert, bag, or label project. It does not identify a customer or claim a fixed order quantity, price, saving, production time, certification, test result, or performance outcome. Those facts belong to a specific project file.
Evidence rule: a photograph can show appearance or a production stage; it cannot by itself prove material grade, tolerance, adhesive performance, transit protection, regulatory status, or shipment conformity.
1 · The project record
Every gate answers one buyer question.
Keep the buyer decision beside the evidence that supports it. This is the difference between a project history and a gallery of attractive images.

| Gate | What is defined | Evidence to retain | Decision |
|---|---|---|---|
| Brief | Product, dimensions, weight, use, opening, protection, brand references, destination, quantity, and target date. | Brief revision, product reference, photos or drawings, and unanswered questions. | Is the request complete enough to discuss structure? |
| Structure | Inside and outside dimensions, board or material build, insert, closure, assembly, and artwork zones. | Supplier dieline, construction notes, version matrix, and quote assumptions. | Can the proposed build be sampled? |
| Sample | Representative production route, materials, finish, fit, function, copy, and open revisions. | Sample photos, measured checks, approval record, revision, and courier handoff. | Does the physical sample represent the intended approval? |
| Production | Released artwork, materials, tools, process checkpoints, packing, and inspection plan. | First article, in-process, final, carton, defect, correction, and release records. | Can the lot be accepted or contained? |
| Shipment | Released quantities, cartons, marks, dimensions, weight, documents, and receiving handoff. | Packing photos, carton list, dispatch evidence, and final delivery references. | Can the receiving team reconcile the delivery? |
2 · What changed at each gate
Good development records explain the revision, not only the final object.
- Brief to structureTranslate the product's actual size, weight, handling, opening, and protection need into a named construction and internal clearance.
- Structure to sampleMove from concept geometry to a supplier dieline and representative material build. Keep the concept image separate from the production reference.
- Sample to releaseCheck dimensions, fit, appearance, finish, function, copy, packing, and open points before the approved revision is released.
- Release to shipmentConnect the inspection disposition to cartons, quantity, marks, packing data, and the handoff owner.
Use the quality inspection checklist when the sample becomes a production reference.
3 · A reusable review sequence
Ask the same five questions before moving forward.
If a question cannot be answered from the project file, keep the gate open and name the owner for the next record.
- 01
What is the approved object?
Identify the product, packaging configuration, revision, dimensions, material build, artwork, finish, insert, and exceptions.
- 02
What can be checked physically?
Define the fit, closure, removal, print, color, finish, protection, packing, and any application-specific observations.
- 03
What evidence is still missing?
List material documents, tests, certificates, inspection records, carton data, destination review, or approvals that are not yet available.
- 04
Who owns the decision?
Name the buyer, supplier, quality, artwork, logistics, or regulatory owner who may approve, revise, hold, or release the next step.
- 05
What is the next dated handoff?
Record the trigger, output, owner, and date for sampling, approval, production, inspection, packing, freight, or delivery.
