Definition
Supplier qualification is the evaluation of whether a supplier has the capabilities, resources, and operating systems needed to meet a defined requirement. Early qualification commonly examines capability, capacity, and financial stability before the buyer proceeds further in procurement.
For VPP, qualification should answer a specific question: can this supplier reliably deliver this requirement under the conditions the business actually needs? A general company profile should not be treated as proof that a particular plant, process, or product is ready.
Qualification is different from onboarding
Qualification evaluates the supplier's ability to meet the requirement, while onboarding establishes the supplier in company systems and prepares it to transact. Supplier approval is the subsequent decision to place an evaluated supplier on an approved list.
Keep those decisions separate. A vendor number, bank record, or signed document should not substitute for the operating evidence required to release production business.
What evidence should be reviewed?
VPP recommends a risk-proportionate qualification plan with clear acceptance criteria. The evidence should be specific to the supply requirement and reviewed by the functions accountable for its consequences.
- Technical fit: Drawings, specifications, materials, process capability, and relevant engineering experience.
- Quality: Inspection methods, traceability, test results, corrective-action practices, and customer-specific requirements.
- Available capacity: Demonstrated output, existing commitments, staffing, equipment, and any required expansion.
- Delivery capability: Lead-time assumptions, logistics arrangements, planning processes, and recovery options.
- Business stability: Appropriate financial, ownership, and reference checks.
- Compliance and continuity: Applicable requirements, subcontracting dependencies, and disruption-response arrangements.
- Readiness to launch: Required samples, trials, approvals, production controls, and an agreed ramp-up plan.
Set the pass criteria before reviewing the supplier's offer. Treat unresolved evidence gaps as conditions requiring action, not as details to be resolved after the award.
Example: Installed capacity is not available capacity
Assume a hypothetical buyer needs 20,000 units per month. A prospective supplier reports capacity of 24,000 units per month, but the review finds existing commitments of 16,000 units.
| Illustrative capacity check | Units per month |
|---|---|
| Reported capacity | 24,000 |
| Existing committed production | 16,000 |
| Capacity remaining under these assumptions | 8,000 |
| Buyer's requirement | 20,000 |
| Unresolved capacity gap | 12,000 |
For this simplified example, assume all units consume equivalent capacity and all figures use the same operating calendar. The comparison shows that the reported capacity alone does not support the buyer's requirement.
VPP would require a credible plan and evidence for the additional 12,000 units before treating the full award as executable. Potential actions could include a validated additional shift, equipment investment, a staged ramp, or a different allocation of business.
Qualification should lead to ongoing control
Supplier quality management includes process controls, quality-assurance plans, performance data, and cross-functional improvement work, not only an initial assessment. VPP recommends carrying the critical qualification assumptions into the supplier's launch plan and performance review.
For example, if approval depends on a specific production line or inspection method, make changes to that arrangement visible. Define who evaluates a material change and whether additional qualification is required.
Frequently asked questions
- Can a qualified supplier be approved for every part or service? Qualification can apply to new suppliers or to an existing supplier seeking approval for new parts or processes. VPP recommends defining the scope of approval explicitly rather than assuming it is universal.
- Does every supplier need an on-site audit? VPP recommends selecting the assessment method according to the criticality of the requirement and the evidence gap. Use documentation reviews, samples, trials, remote checks, or site assessment where each is appropriate.
Establish a supply option you can implement
VPP connects supplier discovery with qualification evidence and the practical requirements of an award. Focus the evaluation on what must be true for the proposed supply arrangement to work.
