Overall Equipment Effectiveness
Learning objectives
- Explain the purpose of overall equipment effectiveness in garment operations.

- Identify common mistakes and how to avoid them.
Core idea
OEE = Availability x Performance x Quality, with all factors expressed as decimals; it diagnoses equipment-related loss, not labor worth.
Method
Define planned time, ideal cycle, good count and loss categories; validate data; analyze six big losses. Avoid comparing unlike equipment or using inflated ideal rates.
Garment-factory example
90% availability x 85% performance x 98% quality = 75.0% OEE for an automated cutting or finishing machine.
Method
- Define planned time, ideal cycle, good count and loss categories;
- validate data;
- analyze six big losses
Common mistakes
- Avoid comparing unlike equipment or using inflated ideal rates
