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 their own washing facility. So they have to send Garments to another factory for washing. Delaying in washing can affect on-time delivery.

  • Washing WIP= Total Garments sent to washing – Total Garments received from washing

  • Finishing sections WIP = Total Garments received from washing – Total packed quantity
