Understanding SAM and SMV in Sewing Operations

In apparel manufacturing, Standard Allowed Minutes (SAM) and Standard Minute Value (SMV) are critical terms for measuring capacity and line balancing.

SMV represents the basic time required to perform a specific sewing operation under standard conditions by a qualified operator. SAM, on the other hand, includes basic SMV plus necessary allowance variables (fatigue allowance, personal delay factor, machine delay allowances).

Industrial engineers in Tirupur utilize SAM values to calculate daily target output, set operator piece-rates, and design line schedules.
