1
Productivity & Operations
Industrial engineering optimizes systems of people, machines, and materials.
Productivity = Output ÷ Input
💡 Exam Hack
Time-and-motion study finds the most efficient way to do a task — eliminating wasted movement.
2
Quality Control
| Tool | Use |
|---|---|
| Pareto chart | 80/20 — vital few causes |
| Control chart | Monitor process variation |
| Six Sigma | Reduce defects |
3
Ergonomics & Safety
Ergonomics designs the workplace to fit the worker, reducing injury and boosting efficiency.
4
Worked Example
A line makes 240 units in an 8-hour shift. Productivity?
240 ÷ 8 = 30 units per hour
Industrial engineers raise productivity by reducing waste, balancing the line, and improving methods — without simply working people harder.
