Frequently asked questions
What is considered a good on-time delivery rate?
Generally, 95% or higher is considered excellent, while 90-94% is good. Rates below 90% may indicate supplier reliability issues requiring attention.
How often should I calculate supplier performance?
Monthly or quarterly assessments are recommended for regular suppliers. Critical suppliers may require weekly monitoring to ensure consistent performance tracking.
Should partial deliveries count as on-time?
This depends on your business needs. Typically, only complete deliveries meeting order specifications and arriving by the agreed date count as on-time.
