Stability Studies	Data showing shelf-life validation under specified storage conditions.
Metrological Traceability	Clear documentation linking measurement results to national or international standards.

Operational Performance Indicators

In addition to technical qualifications, monitor supplier responsiveness and delivery performance:

1. Review **Certificates of Analysis (CoA)** for every batch shipped.
2. Request method validation reports to confirm analytical rigor.
3. Conduct third-party comparative testing when onboarding new suppliers.
4. Perform virtual or on-site audits of production and storage facilities.
5. Evaluate key performance indicators (KPIs):

• On-time delivery rate ≥94%
• Average response time ≤2 hours
• Customer reorder rate >25% (indicates satisfaction)
