Who may supply, at what price
Orders copy whatever the masters hold. May closes with 412 of 486 materials under named sources, 74 sourced by habit, and 41 prices old enough that their next receipt books variance no vendor caused.
◆ The two masters, measuredcoverage and freshness.
| Source governance, 31 May | Materials |
|---|---|
| Source list maintained | 412 |
| No source list, buyer decides | 74 |
| Active purchased materials | 486 |
| Info records | Records |
|---|---|
| Price current within a year | 396 |
| Price older than a year | 41 |
| Info records on file | 437 |
The 74 uncovered materials are where sourcing is a person, not a policy: legitimate sometimes, invisible always. The 41 stale prices are tomorrow’s variance rows, already written, waiting for a receipt. Sample values are illustrative, never client data.
◆ Variance manufactured by master datathe price nobody updated.
When an order copies a stale info-record price, the receipt books a variance that looks like market movement and is actually housekeeping. Practitioners report variance reviews chasing vendors for numbers their own masters caused. Splitting variance by price age answers it in one cut.
◆ The single-buyer riskcoverage gaps have names.
Materials without source lists get sourced by whoever buys them, which concentrates knowledge in people instead of data. The coverage list, cut by buyer, shows exactly whose vacation would stop which purchases.
