Overall Equipment Effectiveness (OEE) is a measurement system used to understand process performance and effectiveness. OEE measures three key factors - availability, performance, and quality - to determine the percentage of planned production time that is truly productive. It accounts for the six big losses that reduce productivity: breakdowns, setups, minor stops, reduced speeds, start-up rejects, and production rejects. Calculating OEE involves determining the availability, performance, and quality percentages and multiplying them together. Tracking OEE is important for strategic planning, investment decisions, and ensuring suppliers deliver as promised. It provides answers about investment confidence and current plant performance.

2. What is OEE? A System That.. Is used to measure and understand performance & effectiveness Equipment Processes

3. What do we mean by OEE? A measurement system that.. Helps us to understand the current process status Supports production planning Facilitates improvement plans Supports investment decisions

4. Key factors of OEE Availability Performance Quality

5. 1. Availability Measures “Productivity Losses” from breakdown times: Remaining time is called “Operating Time” Availability is the ratio of Operating Time to Planned Production Time.

6. 2. Performance Measures “Productivity Losses” from slow cycles The remaining time is called Net Operating Time Performance is the ratio of Net Operating Time to Operating Time

7. 3. Quality Quality takes into account Quality Loss The remaining time is called Fully Productive Time Quality is the ratio of Fully Productive Time to Net Operating Time

8. OEE.. Takes into account all the three factors Availability Performance Quality OEE = Availability x Performance x Quality

9. Six big losses Breakdowns Setup and adjustment Minor stops Reduced speeds Start Up rejects Production rejects

10. How OEE attacks the six big losses

11. Calculating OEE Availability Availabilty takes into account Down Time Loss, and is calculated as: Availability = Operating Time / Planned Production Time Performance Performance takes into account Speed Loss, and is calculated as: Performance = Ideal Cycle Time / (Operating Time / Total Pieces) Quality Quality takes into account Quality Loss, and is calculated as: Quality = Good Pieces / Total Pieces

12. Calculating OEE OEE OEE takes into account all three OEE Factors, and is calculated as: OEE = Availability x Performance x Quality

13. World Class OEE

14. Importance of OEE in the Strategic planning process OEE can save companies from making wrong investment decisions OEE can also be used to ensure that equipment suppliers deliver what they promised! In essence, OEE is the missing link between money and machines!

15. OEE gives you answers to the following questions How confident were you about the investment when you signed the cheque ? Exactly how well is the new plant performing now? Do you use an appropriate measure of machine performance ? In the absence of the OEE measure, how will they ever know?
