o To calculate the actual production we have to see the total working minute in hour without lost time.
o To know target of a worker.
o To evaluate the finishing time of an item or product.
o Production study helps for planning to maintain the layout and line balancing of machine and product.
o For use as the basis for determining the unit cost of manufacture and the wage rate.
o For use the basis for introducing a production control system.

Production Summary of a T-Shirt
Production Summary of a T-Shirt
In comparing between T-shirt and a Stylish 5 pocket Shirt we see that there is a huge
difference in SAM (T-shirt-6.48 and 5 Pocket shirt- 19.53). But in case of costing there is
only $1.95 difference. In this case our concerned industry will give the production priority

Production Summary of a Short Pant
oIn comparing between Cargo Pant and Short Pant we see cargo pant requires more
SAM, more cost, more manpower and processes than a short pant. In this case the factory
should give more priority to short pant. But the Cargo Pant give more profit than a short
pant and it increases the efficiency of worker. Also this item requires a long lead time
which keeps the whole production process busy for a long time.
Comparison Between a Cargo Pant and a Short Pant
This research is based on some effective layout model of different garments items where to use balancing process using short cut method. During the research it is seen thread trimming is being done manually using helper which is non-value added unnecessary operation can be removed by setting auto trimmer along with machine or by using auto machine. The study shows that this balanced layout model has brought a better synchronization among man machine and materials increasing the efficiency and productivity.
Conclusion
