Performance
What performance means in the production context and how it is measured.
Performance describes how fast a machine produces. In the OEE context, the performance factor is the ratio between the actual speed achieved and the maximum possible speed.
Why measure performance?
When a machine produces slower than possible, performance losses occur. These are time losses not caused by downtimes, but by a production speed that is too low during active operation.
Typical causes of performance losses:
Suboptimal machine settings
Quality problems requiring speed reduction
Material differences between batches
Startup losses after a downtime
How ENLYZE measures performance
ENLYZE measures performance using a configured performance parameter. This is a variable that reflects the production speed, for example:
Throughput in kg/h
Speed in m/min
Pieces per minute
The performance parameter is configured together with a quantity unit and time unit so that performance and total quantity can be calculated correctly.
Performance reference: Maximum Demonstrated Speed
A central question in performance measurement is: what is 100%? What value counts as the maximum possible speed?
ENLYZE uses the concept of Maximum Demonstrated Speed (MDS): the highest speed that was stably achieved for a specific product on a specific machine.
The key advantage: the MDS is product-specific. Different products have different maximum achievable speeds. A machine-wide flat reference would lead to misleading performance values.

Performance in OEE
The performance factor is one of the three components of the OEE. It is calculated per order:
The detailed explanation with calculation examples can be found under Performance (OEE).
How to configure performance tracking in the ENLYZE App is described under Setting up OEE tracking.
