| Available production capacity | Confirm capacity for the required bushing type, size, material, and process—not just the plant’s total output. | Monthly capacity by product family; current committed orders; equipment and labor availability. | Compare available capacity with forecast demand, including peak periods and planned growth. |
| Capacity utilization and flexibility | Ask how the supplier handles demand spikes, urgent orders, tooling changes, and production-line downtime. | Recent utilization by relevant production line; overtime arrangements; documented contingency plans. | A very highly utilized line may have limited room for unexpected orders; assess the actual recovery plan rather than relying on a single utilization figure. |
| Lead time and schedule performance | Check standard and expedited lead times, order cut-off dates, and performance against confirmed delivery dates. | Order history or a sample delivery-performance report; clear definitions of on-time delivery and lead time. | Agree on an on-time delivery target and reporting period in writing; evaluate results over multiple months. |
| Raw-material supply | Review sourcing plans for rubber compounds, metal sleeves, bonding agents, and other specified inputs. | Approved-source controls; material traceability; lead-time monitoring; inventory and shortage-response procedures. | Confirm how critical material shortages are detected, communicated, and mitigated, including whether qualified alternate sources are available. |
| Process and equipment capability | Assess whether molding, bonding, machining, and inspection processes can consistently meet the drawing and performance requirements. | Process flow; control plan; equipment maintenance records; measurement-system checks; capability studies where appropriate. | Request process-capability evidence for agreed critical characteristics; interpret results against the customer’s specification and sampling plan. |
| Quality system and launch readiness | Verify quality controls, change management, defect containment, and readiness for production approval. | Quality-system audit results; applicable automotive quality-system certification; APQP and PPAP documentation when required by the customer. | Confirm the required approval process and documentation before placing production orders; certification alone does not guarantee product conformity. |
| Business continuity and recovery | Determine how the supplier would respond to equipment failure, utility interruption, severe weather, or a site disruption. | Documented continuity plan; recovery responsibilities; backup equipment or validated alternate production arrangements. | Ask for a recent review or exercise of the plan and clarify expected recovery times for parts critical to your operation. |
| Inventory and replenishment | Establish who owns finished-goods and safety stock, how inventory is replenished, and how forecast changes are handled. | Written stocking agreement; inventory reports; reorder triggers; shelf-life and storage controls where relevant. | Set stock levels and ownership terms using demand variability, replenishment lead time, and the cost of a supply interruption. |
| Logistics and communication | Check packaging, labeling, shipment tracking, export documentation, and escalation contacts. | Shipping procedure; packaging validation where needed; named supply-chain contact; notification process for delays. | Agree on shipment milestones and the timing of delay notifications before the first production shipment. |
| Commercial and forecast alignment | Review minimum order quantities, forecast commitments, capacity reservations, price validity, and change or cancellation terms. | Written quotation and supply agreement; agreed forecast horizon; defined process for demand changes. | Make sure commercial commitments match the capacity and inventory assumptions used in the supply plan. |
