Standard Allowed Minute(SAM) or SMV is widely used by industrial engineers and garment production people.For the
estimation of the cost of making a garment, SAM value plays a very important role.
SAM (or SMV) means the time (in minutes) that it takes a worker to complete a specific operation or produce a specific garment. The SAM is often calculated by using a stopwatch. Sometimes it’s done by looking at a special table of times that have already been calculated, for every task needed to make a garment.
Equation For SAM :
Standard allowed minutes (SAM) = (Basic minute + Bundle allowances + machine and personal allowances).
Basic time = Cycle time × Performance rating
Cycle time = Total time required to complete full operation
Performance rating = Operator's working speed
Bundle allowances = % on Basic Time (Normally 10)
Machine and Personal allowances = % on Basic Time (Normally 20)
