What is Efficiency? How to Measure Efficiency in Garments Industry?

What is Efficiency?

Efficiency is the ratio of useful work performed by man or machine to the total energy consumed by them. Efficiency deals with the consumption of the least amount of raw material (input) to achieve the highest amount of output.

In the garments industry, Efficiency is the ratio of produced minutes to spent minutes. Where-

Produced Minutes    = Output × Garment SMV

Spent Minutes           = Manpower × Working Minutes (Working Hours × 60)

How to Measure Efficiency?

To measure the efficiency of any operator, any sewing line, any sewing floor or unit and entire factory the formula is-

Here,

Output                        = Number of garments pieces produced by a certain time

SMV                            = Standard Minute Value of the garment

Manpower                  = Number of worker worked (Operator + Helper + ironman)

Working minute        = Total minute work to produce the garments.

Example:

A sewing line produces 1200 pcs in 10 hours. Total worker work 44 and garment SMV is 9.68. What is the efficiency of the sewing line?

Here,

Output                        = Number garments pieces produced by a certain time = 1200 pcs

SMV                            = Standard Minute Value of the garment = 9.68

Manpower                  = Number or worker worked = 44

Working minute        = Total minute work to produce the garments = 10 Hours = 10 × 60 = 600 minutes

If we put all the value in the efficiency formula we will find the efficiency of that sewing line.

So, Efficiency = [(1200 × 9.68)/(44 × 600)] × 100 = 44%

If production is higher with same manpower or time, efficiency also higher.
