What is the SMV of Puffer Vest?

SMV of Puffer Vest is 25.40. In my industrial engineering tutorial series, I am sharing an Operation Breakdown and SMV of Puffer Vest. You can refer to this operation bulletin to learn about various operations involved, SMV and machine requirements in making Puffer Vest Jacket. 

A Puffer Vest is not an easy style to produce in the sewing line. It has lots of complex processes. I have described the operation breakdown of the Puffer Vest with SMV and Machine names here. 

Operation Breakdown of Puffer Vest is done by the following table. In this operation bulletin process list, estimated time, machine name, hourly production target quantity at 100% and 60% efficiency are shown. The estimated time (SMV) shown in the below table will vary according to the product method followed and machine and equipment used in actual production. So please be careful while you use the above estimated time against each operation.

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).
