| Technical capability and part fit | 15% | Demonstrated experience with the required alloy, dimensional tolerances, surface finish, heat treatment, and operating temperature or pressure. | Approved drawings, process-flow charts, capability studies, sample inspection reports, and comparable production references without disclosing customer names. | Supplier accepts drawings without reviewing tolerances, material compatibility, or inspection requirements. | 5: Fully proven 3: Partially proven 1: Unproven |
| Quality management system | 15% | A current ISO 9001:2015 certificate issued by an accredited certification body, with the manufacturing scope covering the supplied parts. | Certificate number, scope, validity, certification-body accreditation, latest surveillance result, internal-audit plan, and corrective-action records. | Certificate scope excludes the production site or product category; repeated corrective actions remain overdue. | 5: Certified and effective 3: System developing 1: No controlled system |
| Material traceability | 12% | Heat, batch, melt, or cast identification remains traceable from incoming material through machining, inspection, packing, and shipment. | Material certificates to EN 10204 Type 3.1 where specified, heat-number logs, transfer records, and segregation procedures. | Manual relabeling, mixed lots, missing heat numbers, or certificates that cannot be linked to the delivered parts. | 5: End-to-end traceability 3: Partial traceability 1: No reliable records |
| Inspection and testing capability | 14% | Inspection plans define dimensional inspection, hardness, pressure testing, balancing, non-destructive examination, and acceptance criteria according to part risk. | Inspection and Test Plan, calibrated equipment list, measurement-system records, test procedures, and sample final inspection reports. | Testing is performed only after a defect is found, or reports contain no equipment identification or acceptance standard. | 5: Risk-based and documented 3: Basic controls 1: Reliance on visual checks |
| Special processes and NDT | 10% | Welding, heat treatment, coating, balancing, radiography, ultrasonic testing, magnetic-particle testing, or liquid-penetrant testing are controlled by qualified procedures when required. | Procedure qualifications, operator qualifications, NDT personnel credentials, calibration records, and independent laboratory reports where applicable. | Unqualified subcontractors, uncontrolled rework, missing procedure revisions, or NDT reports without acceptance levels. | 5: Qualified and verified 3: Limited in-house control 1: Undocumented outsourcing |
| Applicable industry standards | 10% | The supplier can map the part specification to the applicable edition of standards such as API 610, ISO 5199, ASME material standards, ASTM test methods, or customer specifications. | Compliance matrix, controlled standards register, design-review records, and documented deviations approved before production. | Supplier claims general compliance but cannot identify the exact clause, edition, test method, or approved deviation. | 5: Clause-level compliance 3: General compliance 1: Unsupported claim |
| Product and market certifications | 8% | Certifications are selected according to application: ATEX or IECEx for applicable explosive atmospheres, NSF/ANSI 61 for applicable drinking-water components, and NACE MR0175/ISO 15156 for applicable sour-service materials. | Certificate, product scope, material restrictions, certificate database entry, conformity assessment route, and technical file or declaration where required. | A management-system certificate is presented as proof of product certification, or the certificate does not cover the supplied configuration. | 5: Application-specific proof 3: Documentation incomplete 1: Misleading or absent proof |
| Capacity, lead time, and continuity | 8% | Production capacity, tooling availability, critical raw-material sources, and logistics plans support the required annual volume and agreed delivery window. | Capacity calculation, bottleneck analysis, production schedule, business-continuity plan, recovery targets, and backup-process assessment. | Single-source dependence for critical materials, no recovery plan, or delivery promises not supported by capacity data. | 5: Resilient and validated 3: Manageable exposure 1: High interruption risk |
| Change control and nonconformance management | 5% | Material, process, tooling, subcontractor, drawing, and inspection changes require documented approval before implementation. | Engineering-change procedure, deviation forms, nonconformance reports, root-cause analysis, and corrective-action effectiveness checks. | Unreported substitutions, repeated defects, or corrective actions closed without objective evidence. | 5: Closed-loop control 3: Informal control 1: No change discipline |
| Environmental, social, and compliance controls | 3% | The supplier can document applicable environmental, labor, anti-bribery, export-control, and restricted-substance requirements for the sourcing route. | Relevant ISO 14001 or ISO 45001 certificates where required, code of conduct, compliance declarations, audit results, and material-restriction statements. | Missing legal registrations, unclear subcontracting practices, or refusal to provide compliance documentation. | 5: Documented and audited 3: Basic declarations 1: Material compliance gaps |
