On-time delivery: Measure supplier deliveries received on or before the agreed date.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using On-time delivery to answer this question: measure supplier deliveries received on or before the agreed date? Enter On-time deliveries, Total deliveries, Average disruption cost per late delivery; the calculator shows On-time delivery rate. Try changing one number and watch what happens to On-time delivery rate. The answer tells you On-time delivery rate.
Age 15Explain it to a 15-year-oldConnect it to the formula
Define the agreed date and tolerance consistently, and assess reliability alongside quality, lead time and total cost. The rule is On-time delivery rate = on-time deliveries ÷ total deliveries × 100. Its input values are On-time deliveries, Total deliveries, Average disruption cost per late delivery, and the main result is On-time delivery rate. Try changing one number and watch what happens to On-time delivery rate.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is On-time delivery rate = on-time deliveries ÷ total deliveries × 100, evaluated from On-time deliveries, Total deliveries, Average disruption cost per late delivery to produce On-time delivery rate. Define the agreed date and tolerance consistently, and assess reliability alongside quality, lead time and total cost. 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 received on or before the agreed date.
Why the business model works
Define the agreed date and tolerance consistently, and assess reliability alongside quality, lead time and total cost.
Inputs and operating assumptions
This model uses On-time deliveries (at least 0), Total deliveries (at least 0.01), Average disruption cost per late delivery (at least 0). Keep currencies, accounting treatment and time periods consistent with one another.
The formula
On-time delivery rate = on-time deliveries ÷ total deliveries × 100
What the calculator produces
The primary output is On-time delivery rate; it also exposes Late deliveries, Estimated disruption cost. 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.
