How to calculate productivity in garment?

In the garment industry, productivity is a vital metric that significantly influences both efficiency and profitability. Particularly in garment sewing, high productivity levels are essential for optimizing manufacturing operations and ensuring competitive advantage. Understanding how to calculate productivity can help manufacturers identify areas for improvement and implement strategies to enhance overall performance. Here's a comprehensive guide on how to calculate productivity in the garment industry:

How to calculate productivity in garment manufacturing?

1. Define Productivity Metrics:

Before calculating productivity, it's essential to define the metrics that will be used. In the garment industry, productivity is often measured in terms of output per unit of input. Common metrics include:

• Pieces per Operator per Hour (PPOH): This metric measures the number of garments produced by an operator in one hour.

• Pieces per Machine per Hour (PPMH): This metric measures the number of garments produced by a machine in one hour.

• Efficiency Percentage: This metric measures the ratio of actual output to the standard output, expressed as a percentage.

2. Collect Data:

To calculate productivity, you need accurate data on the production process. This includes:

• Total Output: The total number of garments produced in a specific period.
• Total Input: The total number of operators or machines used in the production process.
• Standard Time: The time required to produce one garment under standard conditions.

3. Calculate Pieces per Operator per Hour (PPOH):

To calculate PPOH, use the following formula:

PPOH = Total Output Total / (Operators x Total Hours Worked)
For example, if 1000 garments are produced by 100 operators working 8 hours each, the PPOH would be:

PPOH = 1000 / (100 x 8 ) = 1.25 pieces per operator per hour

4. Calculate Pieces per Machine per Hour (PPMH):

To calculate PPMH, use the following formula:

PPMH = Total Output Total / (Machines x Total Hours Worked)
For example, if 100 garments are produced by 5 machines working 8 hours each, the PPMH would be:

PPMH = 100 / (5×8) = 2.5 pieces per machine per hour.

5. Calculate Efficiency Percentage:

Utilize the following formula to calculate the efficiency percentage:

Efficiency Percentage = (Total Output × Standard Time) / Total Hours Worked x 100
For example, if the standard time to produce one garment is 0.5 hours, and 100 garments are produced in 80 hours, the efficiency percentage would be:

Efficiency Percentage = (100 × 0.5) / 80 x 100 = 62.5 %

6. Analyze and Improve:

Once you have calculated the productivity metrics, analyze the results to identify areas for improvement. Look for bottlenecks in the production process, inefficiencies, and opportunities to enhance performance. Implement strategies such as training programs, process optimization, and investment in advanced technology to improve productivity.

Conclusion:

Understanding how to calculate productivity in the garment industry is crucial for optimizing production processes and boosting overall efficiency. By defining productivity metrics, collecting accurate data, and analyzing the results, manufacturers can identify areas for improvement and implement strategies to boost productivity. Whether it's through automation, workforce training, or process optimization, improving productivity in garment sewing can lead to significant benefits for the industry.
