Illustrative composite: aggregate substitution audit

Boundary: No supplier, source, material, price, distance, performance, or project outcome is established by this illustration.

The question

How could a closer aggregate source be screened without treating geographic proximity or a supplier record as proof of compatibility?

Possible work product

A provenance and specification comparison, uncertainty register, sampling plan, trial-validation sequence, and contingency criteria.

Illustrative outcome

A closer source can be screened for trial validation while retaining the existing source as contingency. No source is qualified by this example.
