Generally, a machine layout plan is made by following an operation breakdown. Because from an operation breakdown, we get the proper idea about which part will join one after another and select the machine for that operation. We have also known how many machine and workers need for each operation from the machine layout plan.

Operation Bulletin of a Leggings: Operation bulletin of a Leggings has divided into 3 parts;

1. Sewing and production data.
2. Machine requisition data.
3. Manpower requisition data. 

1. Sewing and production data: In sewing data included SMV of Sewing and manual operation, production target per hour at 80%, 90%, and 100% efficiency.

Operation Bulletin of Sewing Data
