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 is operation breakdown. You can

visit my website to learn more about the bulletin or breakdown of garments. Thank you
for your patience reading. Please, Share this article with others and subscribe to my page.  

It will inspire me to write more about this.
