Enabling Change control locks the configuration of a given process. By taking this action, you will make the process configuration unmodifiable unless changes are made through a staging copy. 

Configuring Change control

When creating a process, Change control is listed as an option in the Settings menu. 

You will then be navigated to the configuration screen where the option to enable Change control is set via a checkbox.

Once enabled, users will subsequently be unable to amend the configuration of a process. The matched fields will be locked and editing tools disabled. Any configuration changes will have to be made via a staging copy, going through a four-eyes review and approval process.
