The commercial decision
Quality risk is not a list of defects found at final inspection. It is the connection between a failure mode, its cause, the customer or safety effect, the prevention control and the evidence that the control works.
What the evidence can support
High-priority oven risks often include overheated terminations, fan or motor degradation, sensor drift, relay or control faults, door-glass stress, loose protective earth, sharp edges, coating damage, uneven cooking and transit damage. The exact ranking must come from the nominated construction and intended use, not a generic template.
A repeatable way to compare suppliers
Build a design and process risk review, then link critical causes to incoming checks, process parameters, error-proofing, end-of-line tests and reliability validation. During pilot, code every failure and rework by root cause. Use production-intent parts, fixtures, operators and packaging.
Cost and launch consequences
Agree escalation rules before shipment: containment, stop-ship authority, sample expansion, corrective-action timing and cost ownership. Track field return codes against factory failure modes. This turns warranty data into prevention rather than a monthly count.
Boundaries on the claim
A high final pass rate can coexist with heavy rework and unstable processes. Report first-pass yield and the rework path separately. Inspection cannot compensate for a design that has insufficient margin.
