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

A Boys Rain Jacket is not an easy style to produce in the sewing line. It has lots of complex processes. Here I describe the operation breakdown of the Boys Rain Jacket with SMV and Machine names.

Operation Breakdown of Boys Rain Jacket

is done by the following table. In this operation bulletin process list, estimated time, machine name, hourly production target quantity at 100% and 50% 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.

How to set the target per hour in the Sewing line of the Garment Factory?

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). 

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