Choose how deeply to explain Supplier Delivery Reliability
Supplier Delivery Reliability: Measure supplier deliveries arriving on time, complete and on-time-in-full.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Supplier Delivery Reliability to answer this question: measure supplier deliveries arriving on time, complete and on-time-in-full? Enter Deliveries due, Deliveries on time, Deliveries complete, and 1 other input; the calculator shows Supplier on-time delivery rate. Try changing one number and watch what happens to Supplier on-time delivery rate. The answer tells you Supplier on-time delivery rate.
Age 15Explain it to a 15-year-oldConnect it to the formula
Define early, partial and rescheduled deliveries explicitly so suppliers are assessed by the same rule. The rule is On-time delivery rate = on-time deliveries ÷ due deliveries × 100. Its input values are Deliveries due, Deliveries on time, Deliveries complete, Deliveries both on time and complete, and the main result is Supplier on-time delivery rate. Try changing one number and watch what happens to Supplier 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 ÷ due deliveries × 100, evaluated from Deliveries due, Deliveries on time, Deliveries complete, Deliveries both on time and complete to produce Supplier on-time delivery rate. Define early, partial and rescheduled deliveries explicitly so suppliers are assessed by the same rule. 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, complete and on-time-in-full.
Why the business model works
Define early, partial and rescheduled deliveries explicitly so suppliers are assessed by the same rule.
Inputs and operating assumptions
This model uses Deliveries due, Deliveries on time, Deliveries complete, Deliveries both on time and complete. Keep currencies, accounting treatment and time periods consistent with one another.
The formula
On-time delivery rate = on-time deliveries ÷ due deliveries × 100
What the calculator produces
The primary output is Supplier on-time delivery rate; it also exposes Complete delivery rate, On-time-in-full rate. 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.
