Supply assessment

Written definitions for every column.

The opening step is translating what you want into something countable. Columns are standardised to one definition each, and the original kept beside it. Each delivery says how old its parts are.

Overlap reporting
Where segments share records, stated rather than double-counted into a bigger total.
Column reconciliation
Bringing differently named fields from separate feeds onto one agreed set of headings.
Honest residue
The portion we could not verify, reported as unverified rather than as clean.

Ask for a sample first. It is the quickest way to find out whether this is useful.
