01 / THE CUSTOMER PROBLEM
Where projects
can get stuck.
A sample can answer a useful design question without resolving every requirement for the next order. The repeat purchase needs a clear statement of what was approved, what remained open and what has changed. Avoid relying on a short email saying that the part looks good. A practical handover connects the physical sample to its drawing, material, inspection evidence and the customer evaluation that was actually completed.
Questions to resolve early
- A sample exception is carried into the next order even though the buyer intended it to apply only to prototypes.
- A material, finish or process change occurs without reviewing the characteristics affected by that change.
- An old quotation or approval is reused after the quantity, required records or drawing revision has changed.
02 / A PRACTICAL REVIEW ROUTE
Work through the
requirement, step by step.
01Record what the sample approval means
Identify the sample, drawing revision and the checks performed by each party. Separate appearance, dimensional inspection, assembly trial and any other functional evaluation. Record exceptions and remaining tests alongside the decision. If a sample used a temporary deviation or a special preparation step, preserve that condition instead of allowing an informal approval to hide it.
02Compare sample and order conditions
Review material grade and condition, finishing, proposed manufacturing route, inspection, packaging and quantity. Ask which conditions remain the same and which need further confirmation for the intended release. NIST’s process-capability guidance concerns a stable process; a few accepted samples alone do not establish sustained production capability. Agree any additional evidence needed for your project.
03Make changes and release decisions explicit
Use a revision comparison to record old and new requirements, affected parts and the authorized decision. Recheck commercial validity, timing and documentation for the new quantity. Keep engineering approval, customer sample approval and release of the next order as distinct decisions. Retain the original records so later questions can be traced to the conditions actually accepted.
03 / BEFORE ACCEPTANCE
Agree what
the evidence should show.
A general promise of precision is not a project acceptance plan. Confirm the checks and records that apply to your component.
Keep a written approval that identifies exactly which sample and requirements were accepted and which remain open.- Confirm the agreed order conditions and close or explicitly disposition relevant changes before release.
- Link delivery records to the applicable revision and lot; evaluate repeat-order results against the agreed scope.
04 / REAL COMPONENT REFERENCES
Connect the topic
to the geometry.
The referenced Chengshuo products provide published geometry examples. They do not establish a particular customer’s sample approval, repeat purchase, stable production result or delivery outcome. These handover steps are recommended project controls, not a claim of audited company practice.

PROJECT QUESTIONS
Before you send
the next revision.
Does sample approval automatically approve production?
Only the approval’s stated scope applies. Establish what evidence and decisions are required for the next stage, especially if material, processing, quantity or inspection conditions differ. Keep unresolved requirements visible rather than assuming they were accepted.
Can an unchanged part use the previous quotation?
Review its validity and current order conditions first. The drawing may be unchanged while material sourcing, quantity, finishing, documentation or timing has changed. Confirm the applicable quotation and preserve the history of any revised conditions.
Evidence and scope of this study
The referenced Chengshuo products provide published geometry examples. They do not establish a particular customer’s sample approval, repeat purchase, stable production result or delivery outcome. These handover steps are recommended project controls, not a claim of audited company practice.
The proposed application is a review scenario. Final feasibility, performance, inspection scope, price and delivery conditions require confirmation against your current drawing.
