Supplier OTIF: Measure supplier deliveries arriving on time and in full, plus the cost of failures.

Age 5Explain it to a 5-year-oldStart with a picture

Imagine using Supplier OTIF to answer this question: measure supplier deliveries arriving on time and in full, plus the cost of failures? Enter Supplier deliveries, Deliveries on time and in full, Production disruption cost from failures, and 2 other inputs; the calculator shows Supplier on-time-in-full rate. Try changing one number and watch what happens to Supplier on-time-in-full rate. The answer tells you Supplier on-time-in-full rate.

Age 15Explain it to a 15-year-oldConnect it to the formula

Measure against agreed dates and quantities, excluding buyer-requested changes consistently. The rule is OTIF rate = deliveries both on time and in full ÷ total deliveries. Its input values are Supplier deliveries, Deliveries on time and in full, Production disruption cost from failures, Expediting cost from failures, Purchase value from supplier, and the main result is Supplier on-time-in-full rate. Try changing one number and watch what happens to Supplier on-time-in-full rate.

CollegeExplain it at college levelState the model precisely

This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is OTIF rate = deliveries both on time and in full ÷ total deliveries, evaluated from Supplier deliveries, Deliveries on time and in full, Production disruption cost from failures, Expediting cost from failures, Purchase value from supplier to produce Supplier on-time-in-full rate. Measure against agreed dates and quantities, excluding buyer-requested changes consistently. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.

The decision this tool supports

Measure supplier deliveries arriving on time and in full, plus the cost of failures.

Why the business model works

Measure against agreed dates and quantities, excluding buyer-requested changes consistently.

Inputs and operating assumptions

This model uses Supplier deliveries, Deliveries on time and in full, Production disruption cost from failures, Expediting cost from failures, Purchase value from supplier. Keep currencies, accounting treatment and time periods consistent with one another.

The formula

OTIF rate = deliveries both on time and in full ÷ total deliveries

What the calculator produces

The primary output is Supplier on-time-in-full rate; it also exposes Average cost per OTIF failure, Failure cost relative to supplier spend. Change one assumption at a time so the comparison remains explainable.

Before using the result in a decision

This compact model cannot capture every tax, accounting, legal, market or operational condition. Compare the output with current company records, cash timing and the downside scenario before committing resources.
