If you had to pick a single number to judge a supplier’s performance, it would be OTIF. Among the 5 supplier-collaboration KPIs it is the one that condenses the most: it tells you whether deliveries arrive when and how they are needed.
What it is and how to calculate it
OTIF stands for On-Time In-Full: it measures the share of deliveries that arrive on time and complete. The formula is simple:
OTIF = on-time, in-full deliveries / total deliveries
The difference from OTD (On-Time Delivery) is completeness: a delivery that is on time but incomplete is OTD-positive but OTIF-negative. That is why OTIF is the stricter — and more useful — thermometer.
What a good value looks like
A level considered excellent sits roughly between 95% and 99% in many industries. The “right” benchmark depends on context: in critical supply chains expectations are higher. More than chasing an absolute number, what counts is the direction: an OTIF that improves over time is worth more than a high but declining one.
Why it matters for manufacturing
In production, a component that arrives late or incomplete stops a line or forces rescheduling. OTIF therefore directly affects production continuity, inventory levels and end-customer service. Measuring it well is the first step to managing it.
How to improve it
Improving OTIF is a three-step loop:
- Measure reliably, delivery by delivery, distinguishing “late” from “incomplete” — they are different problems.
- Share the data with the supplier: what suppliers see measured, they tend to improve. A shared dashboard aligns both sides on the same numbers.
- Act on the causes: upstream there is often an order visibility problem or misaligned data, rather than supplier ill will.
The cross-cutting lever is visibility: when company and supplier see the same order status in real time, delays surface sooner and OTIF rises.
In short
OTIF measures the punctuality and completeness of deliveries and is the flagship KPI of supplier performance; an excellent value sits between 95% and 99%, but it is the trend that matters. You improve it by measuring precisely, sharing the data and acting on the causes — almost always tied to visibility. It is one of the numbers that feed a portal’s business case.
