All about WIP in Garments industries

WIP ( Work in Process):

Some people requested to write about WIP in Garments. Many of us don’t know that how to calculate WIP. Example, if we calculate cutting WIP, what it’s include? Only cutting parts or fabric laid on table or fabric kept in cutting racks for relaxation?  

WIP or Work in process means the unfinished items or products in a production process. These items are not yet completed but either just being fabricated or waiting in a queue for further processing or in a buffer storage. In garment manufacturing, WIP is generally measured in pieces (unit). WIP can be measured as:

WIP= Total pieces loaded in a process - Total pieces out from that process.

This is the WIP of that process.

To calculate current WIP level -

Cutting Room WIP: 

When one calculates cutting room WIP only stock cut pieces is considered as cutting WIP. Fabric those are layered on table or received from fabric store for cutting is not considered as WIP.

Cutting WIP = Total cut qty - Total qty input to sewing,
For example, Cutting room cut total 20000 pieces for style: A,B,C,D and 15000 pieces have been issued to sewing department. Then cutting room WIP will be 5000 pieces.

Sewing Section WIP: 

WIP level of sewing section can be calculated for a line, for a floor, even WIP between two operations.
Sewing Line WIP = Total pieces inputted to the line - pieces completed from the line.
For example, To Line 1 total 1000 pieces have been inputted for style A and total 2000 pieces have been inputted for style B. Total 1500 pieces are out from the line. Sewing line WIP is (1000+2000)-1500 = 1500 pieces for that day.

Finishing Room WIP:

Finishing room WIP = Total received from sewing - Total pieces packed.

If the goods having washing process, then the formula will

Finishing room WIP = Total received from wash - Total pieces packed.
