Operation Breakdown and SMV of a Trouser

What is Operation Breakdown and SMV?
A breakdown is a list of the elements that comprise the content of a job. A garment is manufactured by a number of sewing jobs and non-sewing jobs. Jobs or activity involved in making a garment is known as operations. When you breakdown a garment, you are writing down all of the parts and all of the operations one after another, lying with the whole garment and following the process sequence.
