Check process fit, not only the machine list
Ask how the proposed machine, setup, workholding and tool access address the actual geometry. A long equipment list does not prove that the supplier has a stable route for your part.
Review quality planning
Confirm drawing control, material identification, in-process checks, final inspection, calibration and nonconformance handling. Request evidence appropriate to the order rather than relying on generic badges.
Test communication quality
Useful questions, documented assumptions and clear escalation paths are strong indicators of project control. Slow or vague clarification before award usually becomes a larger risk after production starts.
Evaluate total delivery risk
Compare lead time assumptions, outside-process dependencies, packaging, logistics, payment terms and the supplier response plan for schedule or quality problems.
