FTT (First Time Through)
First Time Through
Measure of units or transactions that pass through a defined process successfully on the first attempt without rework.
Examples
- 01Final assembly measures FTT by counting cars that leave the line without any repair: 91 of 100 this week.
- 02The weekly quality review compares FTT by model and finds the new variant at 84 % because of wiring harness rework.
- 03When FTT drops sharply after a design change, the team checks the change for missing work instructions.
