Quality calculator
Calculate Right First Time percentage from units checked and units that passed without any rework, with the number of units needing rework and the rework rate.
Right First Time
92%
RFT % = units passed first time / units checked × 100
| Symbol | Meaning | Unit |
|---|---|---|
| U_pass | Units accepted at first check without repair | pcs |
| U_checked | Units checked | pcs |
RFT = units passed first time / units checked × 100. Units needing rework = units checked - units passed. Rework rate = 100 - RFT.
See right first time for how RFT relates to DHU.
Defaults: 300 garments checked, 276 passed without any repair.
Use RFT together with DHU: RFT tells you how many garments needed work, and DHU tells you how many defects there were. Track RFT by line and day with the RFT report template.
No. Right first time counts only units that passed at the first check without any repair.
Yes. Enter submissions as units checked and first-time approvals as units passed.
Right first time measures the share of garments that pass inspection without any repair. How to calculate RFT, how it relates to DHU and defective percentage, and how it is also used for lab dips, samples and shipments.
DHU counts defects per hundred garments checked. The formula, how it differs from defective percentage, a worked example from end-of-line checking, and how to turn DHU data into action on the line.
Inline inspection checks work at or near each operation while the line is running. How the traffic light system works, how to choose operations to check, sample sizes and frequency, and how to act on the results.
A final (pre-shipment) inspection checks a finished, packed lot against the buyer's requirements before it ships. What is checked, how samples are drawn, the order of work, and how to prepare so the lot passes the first time.
