主要ポイント
- Measure variability, not only pass/fail conformity.
- Documentation quality is a leading indicator of operational problems.
- Review on a fixed cadence with the supplier present, not only internally.
What to measure
Conformity rate against specification, spread of key parameters between lots, on-time performance, document accuracy and completeness, and time to respond to a quality query. Four of those five are available from records you already generate.
Consistency over headline quality
A supplier delivering slightly lower but very stable values is often more valuable to a formulation team than one whose results swing across the tolerance band. Scoring should reflect that.
Using the review commercially
A documented performance record justifies allocation decisions, supports tolerance renegotiation and makes corrective action conversations factual. Without records, supplier reviews become impressions.
| Indicator | Source | What it signals |
|---|---|---|
| Specification conformity rate | Receiving results | Technical reliability |
| Parameter spread between lots | Receiving results | Process control maturity |
| On-time arrival | Logistics records | Planning reliability |
| Document accuracy | Import file | Administrative discipline |
| Query response time | Correspondence log | Partnership quality |
確認事項
- Performance data captured automatically from receiving records
- Scorecard shared with the supplier, not only used internally
- Corrective actions tracked to documented closure
管理すべきリスク
- Performance decline invisible because results are never aggregated
- Allocation decisions based on relationship rather than record
- Corrective actions agreed verbally and never verified
よくある誤り
- Reviewing only price at the annual meeting
- Measuring conformity while ignoring variability
- Not re-qualifying after a supplier changes plant or ownership
よくある質問
How often should suppliers be formally reviewed?
Critical ingredient suppliers benefit from a structured review at least annually, with data reviewed continuously and exception reviews triggered by non-conformances.
Should scorecards be shared with suppliers?
Generally yes. A shared, factual scorecard improves performance far more reliably than an internal record used only at contract renewal.
