Scope and common interpretation errors
For engineering changes and order records, within approved customer change procedures.
Dimensions, compound, finish and packaging changes have different effects. An old sample may still represent color but not hole position.
Turn the review into recorded checks
| Step | Action and evidence |
|---|---|
| 1 · Create a change matrix | List old and new requirements, reasons and affected scope. |
| 2 · Label sample uses | Identify valid reference purposes and superseded features while preserving evidence. |
| 3 · Align order attachments | Confirm drawing, BOM, inspection and packaging revisions before issuing controlled production documents. |
A comparison to avoid misinterpretation
After only a locating-hole change, an approved old sample may remain a surface reference but cannot qualify the new hole-position fit.
Frequently asked question
Can a verbal 'small change' go unrecorded?
