Overall Equipment Effectiveness — measure and improve production efficiency
What is OEE?
OEE is the most widely used measure of production efficiency. It combines three factors: Availability, Performance and Quality into a single number that shows how close you are to perfect production.

Overall OEE
73%
85% × 90% × 95% = 73%
The OEE formula
OEE = Availability × Performance × Quality
Availability
Run time ÷ Planned time
Performance
Actual output ÷ Theoretical max
Quality
Good units ÷ Total
The six big losses
Availability
- 1. Equipment breakdowns
- 2. Setup and adjustment
Performance
- 3. Idling and micro-stops
- 4. Reduced speed
Quality
- 5. Start-up losses
- 6. Defects and rework

Calculation formulas
Availability =
Run time ÷ Planned production time
Performance =
(Units produced × Ideal cycle time) ÷ Run time
Quality =
Good units ÷ Units produced
OEE = A × P × Q
Typical targets
Remember
- • OEE is a diagnostic tool, not a goal in itself
- • Focus on reducing the biggest losses
- • Consistency matters more than perfect numbers
- • Involve the operators in data collection
Your current OEE: %
Your target: % by
Improvement opportunity: % = extra units/day
Method: Seiichi Nakajima, “Introduction to TPM”, Productivity Press (1988). World class is taken as about 85 % OEE = 90 % availability × 95 % performance × 99.9 % quality.
