What is Operation Bulletin | How to prepare an Operation Bulletin for a sewing line

Introduction: Operation Bulletin is a summary document of a sewing line. In this document, how many machines and workers are required for making the complete garments is listed. The machine layout for producing garment is done from the operation breakdown of that garment. It is a process of line balancing by which we reduce the SMV of making a garment.

The operation bulletin also helps to remove the bottleneck of the production line. Because we get the proper idea about the machine and worker needed for every operation of a garment.

Prepare an Operation Bulletin

Which type of work and information are recorded in an operation bulletin?

Operation Bulletin is a summary document and it contains some information;

• The hours of daily work.  
• Target production daily or hourly.
• Overall SMV (Sewing SMV and non-SMV).
• Engineer Name who prepared Operation Bulletin.   
• Description of procedure.  
• Description of the machine.
• Overall SMV at 100% Efficiency.
• No. of machines calculated.
• No. of machines currently available. 
• Production estimated per hour per unit. 
• All comments on making the garment. 
• Summary list of machines.

How to prepare an operation bulletin for a sewing line: 

Operation bulletin is an important document for an industrial engineer. Because he estimates the total required man and machines report for the production line. An industrial engineer making an Operation Bulletin by following this flowchart;

Prepare an operation breakdown for the garment

↓

Prepare a machine list for each operation

↓

Calculate each operation SMV

↓

Calculate the production target for each operation

↓

Calculate no. of machine need for each operation according to the production target

↓
Calculate no. of worker and helper need for each operation
↓ 

Calculate total production per hour

↓

Calculate total no. of machine for this garment production

Benefits of making an operation bulletin: There have some special benefits of making an operation bulletin;

• We get a daily production target.
• We reduce bottleneck from the sewing line.
• We get the exact machine number that required for production.
• We get the total number of worker and helper for garment production.
• We do line balancing from the operation bulletin.
• We do machine layout from the operation bulletin.

Operation bulletin is a vital tool of industrial engineering which is used to machine layout planning, line balancing, remove the bottleneck and the total number of worker and helper needed for garment production. It is a document where you will get all type of information about the production procedure.
