How it is calculated

OTIF = orders on time and in full ÷ total orders. On-time delivery ignores quantity. Case fill rate = cases delivered ÷ cases ordered, regardless of time. Read OTIF vs fill rate vs DIFOT.

Questions

How is OTIF calculated?

Orders delivered both on time and in full, divided by total orders, × 100.

Why is fill rate higher than OTIF?

Fill rate counts volume shipped regardless of time, so one short line or late order barely moves it, while it fails the order under OTIF.
