Supplier Qualification
Definition
The formal process of verifying that a prospective supplier can reliably meet quality, capacity, financial, and compliance requirements before awarding them business.
In Practice
Qualification is the gate between finding a supplier and depending on one. Typical stages include a capability questionnaire, financial health check, quality system audit, first-article or sample inspection, and often a trial production run. Regulated industries add layers: process validation, regulatory registrations, and change-control agreements. Only after passing does the supplier enter the approved supplier list that buyers and MRP can source against.
The practical significance for planners is time. Qualification commonly takes weeks to many months, which means you cannot simply switch suppliers when trouble hits, the switching lead time is the qualification lead time. This is why backup sources are best qualified before they are needed.
Example: an automotive tier-one qualifies a new stamping supplier through a PPAP process covering dimensional studies, material certs, and a run-at-rate demonstrating 2,000 parts per day. The full process takes five months, after which the supplier can receive production orders.
