How to Measure Sewing Line Efficiency?
Sewing Line Efficiency
In the garments industry, efficiency is the ratio of produced minutes to spent
minutes multiplied by 100. The formula to calculate Operator Efficiency, Sewing
Line efficiency, Sewing Floor or Unit Efficiency and entire Factory Efficiency
are the same. Just have to change some value to calculate the specific type of
efficiency. In this article, we will learn how to calculate a Sewing Line
Efficiency.

Sewing Line Efficiency Calculation
The common formula to calculate
efficiency is-
Here,
Output = Number of garments pieces
produced in the line
SMV =
Standard Minute Value of the garment
Manpower = Number or the worker worked (Operator + Helper + ironman)
Working minute = Total minute work to produce the
garments.
Example:
A sewing line output is 1600 pcs in 9 hours. The operator was 32, the helper was 4 and the ironman was 2 and the garment SMV is 7.32. What is the efficiency of the sewing
line?
Here,
Output = 1600 pcs
SMV =
7.32
Manpower = 32+4+2 =
38
Working minute = 9 hours = 9 × 60 = 540 minutes
If
we put all the value in the efficiency formula we will find the efficiency of
that sewing line.
So, Sewing Line Efficiency = [(1600 × 7.32)/(38 × 540)] × 100 = 57.08%
