## Performance Losses

Performance losses occur when a machine does not produce at its maximum possible speed. Simply put, it's the extra time required because production did not run at full theoretical performance.

#### Example

For Product A, the maximum performance is **300 kg/h**. During the last production run, however, only **250 kg/h** was achieved on average.\
**Important:** The average performance refers only to **productive time**—i.e., periods without downtime. Downtimes do not influence the average speed and therefore do not affect the performance value.

A total of **3,000 kg** needs to be produced for the order.

1. Production time at maximum performance:

$$
\text{Production Time at Max Performance} = \frac{3000kg}{300 \frac{kg}{h}} = 10h
$$

2. Actual production time at average speed of 250 kg/h:

$$
\text{Actual Production Time} = \frac{3000kg}{250 \frac{kg}{h}} = 12h
$$

3. Performance Loss:

$$
\text{Performance Loss} = 12h-10h=2h
$$

So, production took 2 hours longer than it would have at maximum speed.

## **Performance Factor**

The performance factor indicates what percentage of the maximum performance was actually achieved.

$$
\text{Performanc Factor} = \frac{\text{Actual Performance}}{\text{Maximum Performance}} = \frac{250 \frac{kg}{h}}{300 \frac{kg}{h}} = 83,3%
$$

***

**What is “Maximum Performance”?**\
In this example, a fixed value was used for the maximum performance. In practice, however, the definition of “maximum possible performance” is often a subject of discussion—especially in continuous manufacturing processes.

A well-founded and consistent definition is crucial to accurately analyze and compare performance losses.

## Automatic Performance Tracking with ENLYZE

ENLYZE can calculate the performance of each order, machine, or site. To accomplish this, two requirements need to be fulfilled:

* [Performance Configuration](https://docs.enlyze.com/en/production-optimization/oee#configuring-performance-recording): should be defined for each machine so that we know which parameter needs to be used to measure performance.
* [Booking Data](https://docs.enlyze.com/en/connect/it-connectivity): with orders and products running at the machine must be synchronized within ENLYZE to apply the correct performance thresholds every time.
