Standard Allowed Minute (SAM) is the time necessary to produce one complete garment including the allowances. In garment industry, particularly in production SAM is used for assessing the efficiency of work. In the garment industry, industrial engineering department determine and calculate SAM for assembling process of garments using standard calculation method (Vijayalakshmi 2009). The applications of SAM are Firm as well as individual operator’s performance could be determined by means of SAM Operator and associated cost ratios could be determined using SAM Operators payroll and incentive amount can be calculated based on acquired SAM SAM is one of the key parameter in state-of-the-art production scheduling methods such as line balancing …show more content…

Example: As per previous example factory had an order of 300 pieces. The cutting room records show cutting of 315 garments have been cut but only 290 garments were finally shipped.
Cut to ship ratio = 290/315 = 92% (8% garments were lost/ rejected in the process)
14.6.2 Labour Cost per minute:
This is a significant parameter when estimating the cost of a garment. It assists to determine the labour cost that incurred during the production of garment.
Cost per minute= (Total cost incurred on labour)/(Total available working minutes X No.of labour)
To determine the labour cost of a new style or order its SAM value is estimated and then multiplied to cost per minute and efficiency to get the actual labour cost.
Example: A garment Industry has 500 direct sewing operators and helpers. The cost to company for the 500 operators is Rs. 39,00,000. The company works for 8 hours per day for 26 days in a month. Therefore,
Total working minutes per operator = 12480 minutes.
Cost per minute = 39,00,000 / ( 12480 X 500) = Rs. 0.625 per minute
14.6.3 Plan Performance Index:
This demonstrates the percentage of variation between the planned work and the actual work
