Right First Time is lean tools that mean doing the thing right in the first time which can remove eliminate or repair and defects producing in garments manufacturing. RFT percent is one of the key performance indicator tools in Garments quality control. In this article, we will discuss What is RFT, RFT Factors and Calculation in Apparel Industry.
What is RFT, RFT Factors and Calculation in Apparel Industry
Advantages/Benefits/Importance of Producing Right the First time
Reduce cost and penalty of quality failure
Improve quality and productivity
Remove re-work and repairing
Save time and energy
Save defects rectification cost
Improve work accuracy
RFT calculation for Cutting, sewing, finishing, and Quality Control
Right First Time = (Number of passed goods or Lot / Number of total produced Garments or Lot) x 100
For example, If 200 pcs Garments is produced in the sewing section, found 13 pcs defect by QC then first pass quantity is =(200-13)= 187 pcs.
So, Sewing RFT will be = (187/200*100) % = 93.5%

RFT Key Factor Areas of Garments Manufacturing
There may have others area you need to count RFT, I am giving here what I know. Surely RFT is a performance measuring tool of quality control.
What is WIP, WIP Calculation, Reducing, Reporting in Garments Manufacturing
What is WIP? What does WIP mean in Apparel Industry? WIP means Work In-progress or In-process, an inventory system in the Garments manufacturing process in cutting, sewing and finishing but not for raw materials warehouse or finished goods warehouse. WIP for the manufacturing floor the quantity between input and output what backlogged in production. In this article we will see the details of What is WIP, WIP Calculation, Reducing, Reporting in Garments Manufacturing.
WIP Calculation of Cutting, sewing, Washing, and Finishing
Cutting WIP = Total cut quantity – Total quantity inputted to the sewing section
For example, Cutting section cut total 10,000 pieces for style# 5572819 and 7520 pieces have been inputted to the sewing department, then cutting room WIP will be =(10,000-7520) =2480 pieces.
Sewing Line WIP = Total pieces (GMTS Qty) inputted to the line – Total number of garments sewing output completed
For example, if a sewing Line totals 7520 pieces have been got input for style#5572819 and a total of 3500 pieces are produced from the line. Sewing line WIP is (7520-3500) = 4020 pieces.
Limiting washing WIP is very much important because most factories don’t have own washing facility. So they have to send Garments to another factory for washing. Delaying in washing can effect on time delivery.
Washing WIP= Total Garments sent to washing – Total Garments received from washing
Finishing, the last stage of Garments manufacturing, garments manufacturer challenge limiting washing and finishing WIP. Every factory especially follows up washing and finishing WIP to maintain on-time delivery to the customer.
Finishing sections WIP = Total Garments received from washing – Total packed quantity
WIP Report Format for the Apparel Industry
It is very easy reporting WIP, doesn’t need to make a format for checking WIP, you can keep WIP calculation in a production report. Here excel reporting format uploaded to download for all of you.
