Frame
Define part, material, incoming defect, target and business constraint.
Output: application briefEngineering & Lab
Turn a candidate route into a controlled production process.
Testing is not a generic “sample approval.” It is a traceable comparison of material, part, tool, compound, operating window and acceptance criteria.
Six-gate workflow
Every gate produces an output.
The workflow prevents a persuasive recommendation from being mistaken for a production release.
Evidence
Review approved catalogue records, TDS/SDS, prior tests and known boundaries.
Output: evidence mapDesign
Select candidate process routes and variables to compare.
Output: test matrixTest
Record tool, compound, parameters, result and acceptance evidence.
Output: test recordTransfer
Move the result to the real line and evaluate variation, wear and maintenance.
Output: production trialRelease
Freeze approved materials, settings, limits and change-control requirements.
Output: validated processTest record structure
Evidence must be reproducible.
A useful report lets another engineer understand what was tested, what changed and why the conclusion is valid.

Evidence hierarchy
Source strength depends on the decision.
1Released application-specific process record
Strongest evidence for the stated part, line and scope.
2Traceable lab or line test
Valid within the recorded variables and acceptance criteria.
3Approved TDS / catalogue record
Defines product data or intended use, not the full production result.
4Engineering recommendation
A qualified hypothesis requiring verification.
5Unverified statement
Not suitable for product release or technical claim.
