#### What Should be the Production in Pieces/Machine for a Formal Trouser & Formal Shirt?

Question: What should be the Pcs/Machine for a formal trouser & formal shirt? ... asked by Naushad

Production per machine in a specified duration is known as machine productivity in the specified duration. There are some benchmark for machine productivity for both trouser and formal shirt in national level as well as international level. But that productivity figure varied widely on technology used in manufacturing products, semi-automatic machines, upper head material movements to name a few.

However, for your knowledge formal shirt productivity figure is 9.12 units/ machine per 8 hours shift day (National benchmark, India) and 20.87 units/ machine per 8 hours shift day international benchmark (Hong Kong). For trousers national and international figures are 6.84 units/shift and 19.25 units/ shift respectively (ICRIER, 1993). Average machine productivity on base technology is 8.07 units per shift (Indian factories). (Source: Managing productivity in the apparel industry, Bheda, 2008)

If you are looking for estimated productivity figure of your factory then you can determine it by measuring garment SAM and line efficiency. Derive machine productivity by using following formula:

Formula#1:

Estimated Machine productivity = (Total minutes in a shift * line efficiency / Garment SAM)

SAM of a formal shirt is 20 minutes and your line perform at 60% efficiency then machine productivity is

= 480 * 360%/20 = 14.4 units per 8 hours

Formula #2:

Machine productivity = (Total units produced by the line in shift ours/No. of machined used to make those garments).
