![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Update the system property to add a playbook to the Design and Assign home page in the Telecommunications Network Inventory application. You can launch the Design and Assign function from the home page and execute the steps to achieve your goal.

## Before you begin

Role required: admin, sn_ni_core.inventory_admin

## About this task

Add the change model in the system property to use the playbook for the Design and Assign function. As you add, the Design and Assign home page lists a UI action to launch the playbook.

## Procedure

1. Navigate to AllSystem PropertiesAll.
2. Open the sn_ni_ws.tni_design_assign_chg_models record.
3. In the Value field, add the sys_id of the change model.  
   Note:  
   The default value is the sys_id of the logical connection model that is available in the Design and Assign home page.
4. Select Update.

## Result

The Change model name appears as a UI action in the Design and Assign home page. Selecting the UI action launches the playbook.

## What to do next

Use the playbook to design and assign a service request.
