# Select a change model to fulfill change requests

Select an Operational Technology \(OT\) change model to begin fulfilling your change requests depending on the needs of your organization.

## Before you begin

Role required: sn\_ot\_change\_admin or admin

## About this task

Two OT change models are available for you to use:

-   OT Change Basic
-   OT Change Advanced

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://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/operational-technology/operational-technology-change-management/basic-ot-change-model.md).

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://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/operational-technology/operational-technology-change-management/ot-change-approval.md).

For more information about the Advanced OT Change Model, see [Advanced OT Change Model playbook](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/operational-technology/operational-technology-change-management/advanced-ot-change-model.md).
