Estimating garment production is one of the tasks an engineer and production supervisors do on a daily basis.
This is the basic requirement for production management and each people who are working in production must know how to estimate daily production in a garment factory.
In this post, I have explained the calculation procedure for estimating daily garment production.
Production is the total number of garments stitched by operators in a line in a day. Production is also termed as daily output. To estimate production, you need the following information.
Total available man-minutes =(Total no. of operators * Working hours in a day * 60)
Let's assume

Production is the total number of garments stitched by operators in a line in a day. Production is also termed as daily output. To estimate production, you need the following information.
- Standard allowed minutes (SAM) of the garment
- How many operators are working in the line?
- How many hours line will work in a day?
- Average Line efficiency level?
- Total break time for lunch and tea break (if any).
The formula for production estimation
Daily production = (Total man minutes available in a day/SAM) * Average Line efficiencyTotal available man-minutes =(Total no. of operators * Working hours in a day * 60)
Let's assume
- Garment SAM is 20 minutes,
- Number of operators is 30
- Shift hours in a day = 8 hours
- Average line efficiency =50
- Operators get a total of 45 minutes for lunch and tea break.
Daily estimated production = 13050 /20 * 50% = 326 pieces
You can expect this much output from that line if everything goes well.
Daily production quantity from a line is directly proportional to the line efficiency; the number of operators and working hours. And production is reverse proportional to the garment SAM. If the efficiency of a line increases you can expect higher production.
Similarly, if SAM of style reduces at that also you can expect higher output.

Factors that hamper production:
Anyone of the followings can reduce production of the assembly line. So to get estimated output, you have to take on the following areas.- Machine breakdown
- Imbalance line (WIP control)
- No feeding of cuttings
- Quality problems
- Low operator performance
- Operator absenteeism
