Introduction: Operation Bulletin is a summary of the whole production process. In this document, the industrial engineers who work as layout planner listed all the required things to produce a garment. They make a summary of types of machine, no. of the machine and worker needs to complete the garment in the sewing line.
Common information listed in the machine layout plan:
- Name of the operation.
- Cycle time.
- Calculated production.
- Hourly production target.
- Types of machine used for each operation
- Types of operation done manually by the worker.
- No. of machine required for each operation.
- No. of worker required for each operation.

Generally, a machine layout plan is made by following an operation breakdown. Because from an operation breakdown, we get the proper idea about which part will join one after another and select the machine for that operation. We have also known how many machine and workers need for each operation from the machine layout plan.
Operation Bulletin of a Basic T-shirt: Operation bulletin of a Basic T-shirt has divided into 3 parts;
- Sewing and production data.
