# Measuring performance

The performance factor shows how close a machine produced to its maximum speed. It is calculated per production run and feeds into the OEE as one of three components.

## Calculation basis

For performance measurement, ENLYZE needs two pieces of information:

1. **The actual speed achieved** (measured via the configured performance parameter)
2. **The maximum possible speed** (the [Maximum Demonstrated Speed](/en/concepts/performance/maximum-demonstrated-speed.md) for the respective product)

The performance factor is the ratio:

$$
\text{Performance factor} = \frac{\text{Average speed during production}}{\text{MDS}}
$$

{% hint style="info" %}
The average speed refers only to productive periods. Downtimes do not affect the average speed.
{% endhint %}

## Example

For Product A, the MDS is **300 kg/h**. During a production run, an average of **250 kg/h** was achieved.

$$
\text{Performance factor} = \frac{250}{300} = 83.3%
$$

With a total quantity of 3,000 kg, this results in a performance loss of 2 hours:

* Production time at MDS: 3,000 kg / 300 kg/h = **10 h**
* Actual production time: 3,000 kg / 250 kg/h = **12 h**
* Performance loss: 12 h - 10 h = **2 h**

## Prerequisites

For ENLYZE to calculate performance, the following conditions must be met:

* A **performance parameter** is configured (a variable that measures production speed).
* **Production run data** is synchronized (so the MDS can be determined per product).
* At least one completed production run for the product exists (so an MDS value is available).
