| 1. Application Definition | Machine and undercarriage compatibility | Machine model, operating weight, track pitch, shoe width, roller count, sprocket tooth count, and installation drawings. | Match the supplier's dimensional drawing against the machine manual and the buyer's measured sample. Confirm mounting-hole pattern, pitch, guide height, and chain-link geometry before quotation. | Critical | 15% |
| 2. Supplier Qualification | Quality-management system | Quality certificate, certificate scope, production-site address, audit history, corrective-action records, and quality-control organization chart. | Verify certificate validity through the issuing certification body. The scope should cover the relevant manufacturing activities; an expired or unrelated certificate should not receive full credit. | High | 10% |
| 3. Material Control | Steel grade and traceability | Material specification, heat number, supplier mill certificate, chemical composition, mechanical properties, and traceability procedure. | Require a material certificate such as EN 10204 Type 3.1 for applicable steel components. Confirm heat numbers are traceable from incoming material to finished track-group parts. | Critical | 12% |
| 4. Manufacturing Review | Heat treatment and wear resistance | Heat-treatment process flow, furnace records, hardness results, sampling plan, and test method. | Review hardness testing against the agreed engineering specification. ASTM E18 is commonly used for Rockwell hardness testing; the buyer should define the required hardness range by component and application rather than accepting a generic claim. | Critical | 13% |
| 5. Product Validation | Dimensional and functional testing | Inspection report covering pitch, pin diameter, bushing diameter, shoe width, link height, bolt-hole position, and assembly fit. | Use calibrated measuring equipment and compare results with the approved drawing. Conduct a physical trial assembly on the target machine or a verified fixture before mass production. | Critical | 12% |
| 6. Field Reliability | Wear-life and failure-risk evidence | Reference applications without disclosing customer identities, operating conditions, service hours, failure statistics, warranty claims, and replacement-part records. | Separate results by soil type, duty cycle, machine weight, and operator conditions. Do not compare wear-life claims unless test conditions and measurement methods are equivalent. | High | 12% |
| 7. Quality Inspection | Pre-shipment inspection and sampling | Inspection and test plan, control plan, nonconformance procedure, final inspection report, and agreed acceptance-sampling level. | Use a documented sampling plan such as ISO 2859-1 where appropriate. Define critical, major, and minor defects in the purchase contract; critical safety-related defects should require zero acceptance. | High | 10% |
| 8. Commercial Review | Total landed cost | Unit price, tooling cost, packaging cost, freight basis, insurance, duties, payment terms, warranty reserve, and spare-part pricing. | Compare total landed cost rather than unit price alone. State the selected Incoterms® 2020 rule, named place, currency, validity period, and responsibility for export and import formalities. | High | 10% |
| 9. Delivery Capability | Capacity and supply continuity | Monthly capacity by product family, current utilization, production schedule, critical-subcontractor list, raw-material coverage, and business-continuity plan. | Check whether stated capacity is supported by equipment, staffing, and documented production records. Require advance notice for material, process, tooling, or production-site changes. | High | 8% |
| 10. Logistics and Packaging | Export packaging and cargo protection | Packaging specification, corrosion-protection method, lifting points, gross and net weights, carton or pallet dimensions, and shipping marks. | Approve a packaging sample before shipment. Confirm packaging is suitable for the selected transport mode and complies with applicable wood-packaging requirements when timber is used. | Medium | 3% |
| 11. Warranty Management | Warranty scope and claims response | Warranty period, coverage exclusions, evidence requirements, response time, replacement policy, credit procedure, and root-cause-analysis format. | Write measurable service obligations into the purchase order. Require corrective-action documentation for repeated failures and retain failed parts for joint analysis. | High | 3% |
| 12. Final Selection | Weighted supplier score | Completed scorecard, audit findings, sample-test results, commercial comparison, risk register, and management approval record. | Use a 100-point weighted score. A practical approval rule is to require at least 80 points overall, no unresolved critical nonconformity, and successful sample validation before serial purchasing. | Critical | 2% |
