# What's a Good Way to Track Supplier Lead Time Reliability?

A good way is to compare quoted lead time against actual delivery time for every order, letting a dashboard calculate reliability automatically rather than relying on a quoted estimate alone. On **Jestor**, this runs through dashboard indicators comparing quoted and actual lead times.

Relying only on a supplier's quoted lead time, without tracking what actually happens, means production planning is built on an estimate that might not reflect real performance.

## What relying on quoted lead time alone costs

- Production planning based on an estimate that may not reflect real performance
- No visibility into whether a supplier's actual lead time is consistently longer
- Risk of a production delay from an unreliable lead time that was simply assumed
- Difficulty comparing suppliers on reliability, not just their quoted number

## How tracking lead time reliability works

- Quoted lead time compares against actual delivery time for every **order**
- A dashboard calculates reliability automatically, updating continuously
- Patterns reveal whether a supplier consistently meets or misses their own estimate
- Comparing suppliers on real reliability becomes direct, not based on a quoted claim alone

## Why Jestor fits this use case

- Real tracking replaces a quoted estimate with actual, verified performance data
- Production planning benefits from knowing genuine reliability, not just a claim
- Comparing suppliers on reliability supports more informed sourcing decisions
- This scales from a handful of suppliers to a large, diverse supply base

| Risk of unverified assumption | Based on real delivery data   |

## Frequently Asked Questions
