A practical supplier qualification framework covering technical fit, quality, capacity, cost, lead time, continuity and open checks.
Technical fit
Confirm that the supplier actually uses a suitable process for the material, geometry, tolerance and production volume. Marketing claims are not a substitute for process evidence.
Quality evidence
Review the scope—not only the logo—of certifications. Clarify inspection equipment, traceability, control plans and relevant industry requirements.
Capacity and timing
Separate sample timing, first-production timing and repeat lead time. Ask how capacity is calculated and which operations are outsourced.
Commercial fit
Clarify MOQ, tooling ownership, setup charges, packaging, payment terms and the assumptions behind the quoted price.
Open checks
A strong qualification report makes unresolved points visible so they can be validated before nomination.
Working on a supplier search?
CAS can turn these principles into a scoped supplier search, qualification or RFQ project.
