Concession
Also called: Deviation, waiver
A customer’s permission to use or ship parts that don’t fully meet the specification, limited to a quantity, lot or period.
Concessions let production continue while a problem is fixed, for example by accepting one lot with a cosmetic defect after 100% sorting. They should state exactly what is accepted, for how many parts and until when.
Once the limit passes, the normal specification applies again.
Where it goes wrong
A one-lot concession given on a call is cited again for later lots, and defects get accepted without anyone deciding to.
What Spurby does
Records each concession’s limits and flags any shipment that goes beyond them.
