Formula to set the 100% target:

Daily Target = (Worker x Working hour x 60/ SMV) x efficiency %

Basic Pitch Time (BPT) =Total SMV / Total Manpower

Operation Bulletin makes our work easy to set up a production line in the apparel industry. We can easily manage machine and operator requirements for any sewing line by this. But it is necessary to do an operation breakdown to prepare a machine layout and line balancing by industrial engineering (IE). 

Visit here to know what operation breakdown is. You can visit my post to learn more about the bulletin or breakdown of garments in the garment industry.
