Direct answer: The customer’s designated engineers approve an AI-generated assembly and retain engineering authority. The AI system may produce a proposal, execute bounded CAD operations and report evidence, failures or unknowns. It should not approve its own output, sign a release, replace the engineer of record or change the customer’s established safety and quality responsibilities. Roles and escalation paths must be defined before a pilot.
How the controlled workflow works
- Assign owners for source documents, part master data, rules, discipline review, exceptions and production release.
- Define which low-risk actions may execute automatically and which require pre- or post-action human approval.
- Present the native result, evidence and unresolved obligations in a form the named reviewer can inspect.
- Record approvals, overrides, rejected output and release decisions without attributing them to the AI system.
What evidence should a reviewer inspect?
| Review item | What it can establish |
|---|---|
| Responsibility matrix | Names who owns input truth, design decisions, exceptions, review and release. |
| Approval and override log | Distinguishes system execution from human engineering decisions. |
| Release-system record | Shows that production authority remains in the customer’s governed process. |
Where this answer stops
Human review is not a generic disclaimer; it must have defined competence, access to evidence, sufficient time and authority to reject the result.
Human engineering authority
MST does not claim autonomous production release. Customer production-release approval remains required and outside the AI engineering process.
