Supplier Material Substitution Approval Chain

Reconstruct whether substituted components received technical and contractual approval before production use.

What it checks:

• match substituted part and approved equivalence scope
• resolve effective date and affected lots
• identify unsupported verbal waivers
• propose containment and documentation

Deliverables:

• substitution genealogy
• unauthorized-use exceptions
• approval gate checklist

Typical case: A plant uses alternate connectors during a shortage, but the waiver covered only prototypes, not customer shipments.
