Begin with the requirement, not the supplier brochure
Write down the part, assembly or service outcome before comparing providers. Include the intended use, expected volume, critical features, target dates and the evidence you will need at acceptance.
A provider can be capable in general and still be a poor fit for a particular material, tolerance, batch size or regulatory context. Evaluation becomes clearer when every claim is tested against the same requirement.
- Part or service scope
- Prototype and production quantities
- Critical quality features
- Required records and approvals
Look for process evidence
Ask how the work moves from incoming information to planning, production, inspection and release. The answer should connect people, machines, controls and records rather than rely only on equipment lists.
- Comparable process experience
- Capacity and bottleneck awareness
- Inspection ownership
- Revision and traceability control
Separate certification from capability
A management-system certificate can support confidence in the organisation's controls, but it does not prove that every machine, material or product requirement is covered. Check certificate validity and scope, then review job-specific evidence separately.
Agree the working rhythm
Clarify technical queries, change control, inspection reporting, nonconformance handling and escalation before placing critical work. A strong operational fit is visible in how uncertainty is surfaced and resolved.
- Named technical contact
- Response and review points
- Change approval path
- Corrective-action expectations
