# Changes and maintenance windows

Changes with impact calculated before submission and dates only within maintenance windows.

ITIL 4 practice · Change enablement

## What it does

-   Change models with steps and lead time, impact calculated before submission
-   Slots only inside maintenance windows, outside freezes and collisions
-   Controlled items change state only through a change, including maintenance and retirement
-   Change calendar, rolling execution and a post-change review

## Measurable benefits

1.  **Change success rate**share of changes completed without issues and without alerts afterwards
2.  **Overdue changes**number of changes not completed on the planned date
3.  **Incidents caused by change**number of incidents with a change marked as their cause

The application calculates these indicators from your own data, so you can prove the improvement with numbers from the first month.
