  What is Operation Bulletin? Operation Bulletin (OB) is a worksheet which is containing complete details of “ How exactly going to manufacture the product in the production line. ” It is prepared by Industrial Engineer based on style details. Operation bulletin is containing a complete and clear flow process with SMV. Without appropriate cause adding up (or) reducing down on operation bulletin details is inadequate action. What are the details contain operation bulleting? Operation bulletin is a package which is containing details for a particular style.   i.e. Style details, sketch, order details, process breaks down, SMV, target, workstation type, machine description, attachments details, folder details, work station required, manpower required, total machines, total workstation, total SMVs, total manpower required, planned Output, planned worker efficiency, planned workers efficiency, planned global efficiency, planned pieces per machine, planned pieces per worksta...

  12 FACTORS TO CALCULATE ACCURATE THREAD CONSUMPTION  What is thread consumption per garment? How many threads required to sew a garment is called thread consumption. Sample selection for thread consumption calculation is very important, we have to select the right sample and size. Thread consumption calculation should consider proper allowance to avoid thread shortage or exceeding. Even thread cost is low than other cost of garment materials, thread consumption calculation is a very sensitive process. Providing incorrect thread consumption may lead to issues in production and delivery. Thread consumption formula, Thread consumption = (Seam length x Frequency x Factor) / 100 + Allowances What are the facts that should be consider making an accurate thread consumption report. 1. Samples Type When we select the sample for thread consumption calculation, we must be checked the type of sample. As below mentioned there are many types of samples. In all of them, we ha...
