What is Right First Time Quality in Apparel Manufacturing

The Right First Time (RFT) production is one of the KPIs for garment manufacturing. Like you check garments and measure defective percentage in a lot and defects per hundred units (DHU) in a lot, RFT is another measure of quality performance of a plant. By measuring RFT, a garment factory can figure out the quality level of the production process.

Most of the garment manufacturers concentrate on finding defects and counting the defective units during garment checking and lot inspection. Normally, the Pass/Fail percentage is measured additional to DHU and Percentage defective measures by garment manufacturers. Remember, the pass percentage of a lot is not the RFT. The reason, in a passed lot, few defective garments may be added after correction. So, you will not get the real number of garments that were defect-free.

In defective percentage measure, you get to know how many defective garment units are found against 100 garments checked.

In RFT measure, we count how many garments are passed without any defects out of total production quantity. The RFT production percentage is number for passed units against 100 produced garments.

The formula for RFT production%
RFT = (First time passed units *100)/Total production units
Example of RFT:

Production quantity = 400
First time passed quantity=380
= (380/400)*100 = 95%

Few more examples of RFT data is shown in the following table.
