UNDERSTAND THE CONCEPT
Overall equipment effectiveness combines availability, performance and quality: OEE = A × P × Q. Express each factor as a fraction. Availability uses run time over planned production time; performance compares actual output with the ideal rate; quality uses good output over total output.
Agree the production boundary and definitions before comparing areas. Batch, continuous and mixed-product operations may need careful treatment of rates and quality. A high combined score can hide deterioration in one factor, so show the components and the data behind them.
Questions to take back to your team
- Is planned production time defined consistently?
- Does the ideal rate match the product and process?
- Are quality losses counted on the same output basis?
