What is Productivity
Productivity is the ratio of output to input. In garments, output is usually pieces produced, and input is usually labor hours, machine hours, or total cost. Higher productivity means more output for the same input, which directly increases profit.
Types of Productivity
Labor productivity equals output divided by labor hours. Machine productivity equals output divided by machine hours. Material productivity equals output divided by material used. Total factor productivity equals output divided by total inputs. Each type shows a different part of the picture.
Practical Example 1 — Labor Productivity
A line of 30 operators produces 900 pieces per day. Labor productivity is 30 pieces per operator per day. If output rises to 1050 pieces with the same 30 operators, productivity is 35 pieces per operator, a 16.7 percent gain.
Practical Example 2 — Machine Productivity
A cutting machine cuts 1200 pieces in 400 minutes. Machine productivity is 3 pieces per minute. If downtime drops and 1500 pieces are cut in 400 minutes, productivity is 3.75 pieces per minute.
Practical Example 3 — Material Productivity
The cutting section uses 1050 meters of fabric to produce 1000 pieces. Material productivity is 1000 divided by 1050 equals 0.95 pieces per meter. Reducing fabric waste by 3 percent raises this to 0.98.
Practical Example 4 — Factory Level
A factory has 1000 operators and produces 25,000 pieces per day. Productivity is 25 pieces per operator. If the factory reaches 30 pieces per operator, output rises to 30,000 pieces per day.
Factors That Affect Productivity
Skill, absenteeism, line balancing, machine condition, material availability, style complexity, supervision, motivation, incentives, and layout.
How to Improve Productivity
Train and multi-skill operators. Improve line balancing. Reduce absenteeism with attendance bonuses. Use 5S and visual management. Implement kaizen. Reduce machine downtime with TPM. Improve material flow with feeders. Set realistic targets and track daily.
Common Mistakes
Measuring productivity without adjusting for style complexity. Forcing overtime to raise output, which lowers long-term productivity. Focusing only on the fastest operator. Not tracking at all. Not linking productivity to rewards.
Productivity vs Efficiency
Efficiency measures how well standard time is used. Productivity measures output per unit of input. Efficiency can be improved by reducing downtime without hiring. Productivity can be improved by adding more output per worker. Both matter.
When to Use It
Productivity is tracked daily, weekly, and monthly. It drives capacity planning, pricing, and profitability decisions. It is a core KPI for IE, production, and management.
