Input Factors
Formula Used
Each input is converted into Risk Points from 0 to 100, where 0 is best and 100 is worst. The final score is a weighted average of those points.
Risk Score = Σ( Weighti × RiskPointsi ) ÷ 100
- Linear scaling is used for most factors, with best and worst thresholds.
- Capacity utilization uses a “sweet spot” band (60–85%) and increases outside it.
- If your weight entries do not sum to 100, they are normalized automatically.

Example Data Table
| Supplier | Defect % | OTD % | Audit | Risk Score | Risk Level |
|---|---|---|---|---|---|
| Atlas Components | 1.2 | 96 | 92 | 15.5 | Low |

Notes
- Use the same measurement window across suppliers for fair comparison.
- Update scores after major events: process change, ownership change, or new compliance findings.
- Pair this score with on-site verification for high-risk categories.
Risk scoring aligns quality and sourcing decisions
A consistent 0–100 supplier risk score turns mixed KPIs into one comparable signal. Quality teams can rank suppliers, set review cadence, and justify controls with evidence. For example, a shift from 25 to 45 often reflects compounding drivers rather than a single issue. Use the score to trigger actions: <30 routine monitoring, 30–59 targeted audits, and ≥60 formal mitigation with executive visibility. Track month-over-month deltas to confirm sustained improvements after corrective actions.
How inputs translate into comparable risk points
Each input becomes Risk Points from 0 to 100 using clear thresholds. Defect rate scales from 0% best to 10% worst, while delivery and audit scores treat higher values as better. Financial stability and incident counts capture exposure beyond defects. Capacity utilization uses a sweet spot of 60–85%; very low utilization can indicate instability, while very high utilization reduces flexibility during demand spikes. These mappings keep scoring transparent during supplier review meetings.
Weighting rules support different product risk profiles
Weights let you reflect product criticality and business context. A medical device line may weight defects and audit scores heavily, while a seasonal consumer program may emphasize on-time delivery and lead-time variability. If weights do not sum to 100, normalization preserves your intended proportions and prevents math errors. Review weights quarterly and after major events, such as process relocation, new sub-tier sources, or ownership changes. Document weight changes to maintain audit-ready traceability.
Using top drivers to plan corrective action
After calculation, focus on the top three contributing drivers rather than the raw score alone. If single-source dependency and CAPA closure time dominate, dual-qualification and faster containment will usually move the needle faster than broad inspections. Treat the score as an input to supplier development: define owners, due dates, and measurable targets like defect PPM reductions or on-time delivery recovery. Re-score monthly until stable. Use weekly trend charts to detect backsliding early.
Export-ready records improve accountability and audits
Exportable outputs support disciplined communication. The CSV is useful for adding scores to a supplier dashboard, combining sites, or calculating average risk by commodity. The PDF report summarizes the score, level, top drivers, and recommended actions for approvals and audits. Store exports with the evaluation date, KPI source, and approver. When a supplier disputes a rating, the structured breakdown speeds resolution and improves trust. Over time, this creates a consistent governance history.
FAQs
What does a higher risk score indicate?
It indicates higher exposure across quality, delivery, and operational factors. Use it to prioritize audits, tighten controls, and initiate mitigation plans for the biggest drivers.
How should weights be selected?
Start with your critical-to-quality requirements and business impact. Increase weights for metrics that historically predict escapes, line stops, or shortages, and keep changes documented.
How often should I recalculate the score?
Recalculate monthly for active suppliers and after major events such as tooling moves, new sub-tier sources, repeated defects, or late deliveries. Use trends, not single points.
What if I do not have a metric for a supplier?
Use the best available proxy, or apply a conservative value and note the assumption. Avoid leaving gaps; missing data can hide risk and reduce comparability.
Can I compare suppliers across different commodities?
Yes, if definitions and time windows match. For very different categories, adjust weights to reflect risk drivers, then compare within each commodity group for fairness.
Does the score replace supplier audits?
No. It complements audits by pointing to where to focus. Combine the score with process verification, capability studies, and on-site observations for robust decisions.
