### **Rework %**

<div data-with-frame="true"><figure><img src="/files/NzQNE1VnfdLGai1VI65z" alt=""><figcaption></figcaption></figure></div>

**Rework %** measures the number of changes made to code in the last 30 days.\
If the change is made to a code older than 30 days, it is automatically classified as [<mark style="color:purple;">maintenance</mark>](/metrics-and-definitions/quality/maintenance.md). (30 days is the default setting, you can configure it based on your internal process by going to **Settings -> Configuration**)

* Low rework means the code changes aren't done after the initial work, which indicates that the developers are pushing high-quality code the first time.
* High rework rates are caused by PR feedback, QA feedback, or an engineer trying to improve the code after committing. Too many changes.
