An attractive sample can pass a visual review while leaving important risks unresolved. Set acceptance criteria before ordering it so that the result supports a decision rather than another round of guesswork.
Practical checks
- Write down the question and the measurable pass condition.
- Separate geometry checks from material and life-performance checks.
- Choose a prototype process that represents the property being assessed.
- Record the result, revision and remaining limitations before the next iteration.
Record the finding against the actual part, machine or drawing revision. A useful check identifies both the observation and the conditions under which it was made, so another person can review it.
Common mistakes to avoid
- Do not use an appearance model as evidence of production strength.
- Do not change several features without recording which change answered the original problem.
What to collect before a review
- Current design revision
- Test objective and acceptance criteria
- Assembly context and expected use
Send clear original files where available. Mark uncertain dimensions, missing information and the result you need. Separate confirmed requirements from assumptions instead of filling the gaps with guessed specifications.
The next decision
Use the result to approve, revise or stop the next step. Keep prototype limitations visible when discussing production cost, material or service performance.
