# Measuring performance

The performance factor shows how close a machine produced to its maximum speed. It is calculated per order 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 an order, 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).
* **Order data** is synchronized (so the MDS can be determined per product).
* At least one completed order for the product exists (so an MDS value is available).

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.enlyze.com/en/concepts/performance/measuring-performance.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
