Difference Between Operator Performance And Operator Rating

The term "Standard Hours Earned" (SAH) is not often used in the garments industry. People of the garments industry use "Standard Minutes Produced" or "Standard Minutes Earned." Instead of "Standard Hours Earned". But they have no difference actually as mathematical calculation.

 

We know that,

Produced Minutes or Earn Minutes = SAM of Operation × Total Piece Produced of that Operation
Just if we divide the above expression by 60, it will be directly converted to "Standard Hours Earned" or SAH.

 

Let's say an operator produces 120 garment parts which SAM is 0.35.

Then Produced Minutes or Earn Minutes = 0.35 × 120 = 42.
If we divide 42 by 60, it will be converted to "Standard Hours Earned" or SAH.

That mean SAH of that operation is = 42/60 = 0.7
 
So finally, the formula for "Standard Hours Earned" or SAH = (SAM of Operation × Total Piece Produce)/60

The benefit of using Standard Earned Hours

It is simple to compare the number of hours generated against the number of hours available in a day.
Knowing the Standard Earned Hours of the operators makes figuring out their hourly wage (in dollars) straightforward.
