{#select-change-model__ul_ffs_bxf_xwb}

The OT Change Basic model uses the change process without approvals.

For more information about the OT Change Basic Model, see [Basic OT Change Model playbook](https://servicenow-prod.fluidtopics.net/TQw55mrBhk13no2kWMR50w "Learn about the Basic Operational Technology (OT) Change Model playbook stages that an OT change without approvals must go through until it’s completed.").

The OT Change Advanced model uses the change process with approvals. You can create a change approval policy and assign an approval group to review your change request. For more information about change approvals, see [Operational Technology change approval](https://servicenow-prod.fluidtopics.net/0w~YyEY~bL6tVWqmtr76fg "The Operational Technology (OT) change approval lets reviewers approve your requested changes and suggest improvements as necessary.").
