# Enterprise - Fail Fast

## What is the Fail-Fast Strategy?

In large-scale data collection, collection tasks can stall for extended periods or wait inefficiently due to network delays, blocking, abnormal responses, and more.

Listly Enterprise applies the **'Fail-Fast Strategy'** to data collection features to minimize these issues.

The 'Fail-Fast' feature lets you configure the system to stop all remaining tasks in a group and move to the next task when a certain percentage or number of failures is detected during group extraction.

{% hint style="info" %}
The Fail-Fast feature is configurable when creating a [group extraction](/getting-started/result-page-features/group-extraction.md) task.
{% endhint %}

{% step %}

#### After extracting the source page, click the \[+Group] button

**This feature can be configured during the process of creating a** [**group extraction**](/getting-started/result-page-features/group-extraction.md) **task.** After extracting the source page, click the **\[+Group]** button at the top of the results page.
{% endstep %}

{% step %}

#### After entering URLs in the new group, configure the Fail-Fast option

**After entering URLs in the new group, configure the Fail-Fast option**.

<mark style="color:red;">➊</mark> Percentage setting: When tasks fail at the selected percentage, remaining tasks are marked as failed.

<mark style="color:yellow;">➋</mark> Count setting: When tasks fail at the entered count, remaining tasks are marked as failed.<br>

For testing, we set the percentage to 30% and entered 10 URLs to create the group. To simulate a failure scenario, we intentionally entered incorrect URLs.

{% endstep %}

{% step %}

#### Check task progress

Below is the example result screen. When extraction failed for 30% (3 out of 10 URLs), you can see that the remaining 7 tasks were automatically Fail-Fast processed.

By utilizing the Fail-Fast feature like this, you can reduce unnecessary wait times in certain situations and **significantly shorten overall process time**.
