OEE in a nutshell
What is OEE?
OEE stands for “Overall Equipment Effectiveness”. It is a KPI that measures the effectiveness of industrial machinery and identifies the percentage of planned production time that is truly productive. An OEE score of 100% represents perfect production: manufacturing only good parts, as fast as possible, with no downtime.
OEE benefits
The correct analysis of OEE as a KPI detects potentials to improve the performance of the manufacturing process and delivers several starting points for continuous actions:
- Downtimes and inactive times of the machines are reduced significantly
- Reasons behind a loss of performance (bottlenecks and slow speeds) are identified
- Minimizing losses created by manufacturing defective products, reducing scrapping costs and increasing product quality
- Reliable real-time information of processes significantly increases employee efficiency, and facilitates their work

What is a „good“ OEE score?
- An OEE score of 100% is perfect production: manufacturing only good parts, as fast as possible, with no stop time. In reality this score is impossible to achieve.
- An OEE score of 85% is considered world class for discrete manufacturers. For many companies, it is a suitable long-term goal
- An OEE score of 60% is fairly typical for discrete manufacturers, but indicates there is substantial room for improvement
- An OEE score of 40% is not at all uncommon for manufacturing companies that are just starting to track and improve their manufacturing performance. It is a low score and in most cases can be easily improved through straightforward measures (e.g. by tracking stop time reasons and addressing the largest sources of downtime – one at a time)
