Supplier lead-time decision
The supplier averages 4 days against the quoted lead time and delivers 75% of reviewed orders on time. Your current buffer covers about 5 days of demand.
Recommended next actions
- ✓ Use actual rather than quoted lead time in reorder calculations.
- ✓ Agree a corrective-action target when on-time delivery falls below policy.
- ✓ Review alternate suppliers for high-value or critical items when risk remains high.
