# Configure Design and Assign function

# Configuring Design and Assign function for your network services {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Create and configure a Design and Assign function in the Telecommunications Network Inventory application. You can use it to design your network service and assign the network resources.

The Design and Assign function is created and configured in the Workflow Studio using the playbook experience. Some of the configuration is performed in ServiceNow AI Platform. These settings include creating record producers, Change model, and request definitions. You can fully automate your Design and Assign function by linking flows, actions, and subflows
together in a playbook.  
Follow the steps to create and configure a Design and Assign function.

1. [Create a Change Model](https://servicenow-prod.fluidtopics.net/Azm3oF4rUiWW6FJ~PzsUOg "Create a Change model and add the model states and model state transitions. You can use this Change model to configure a Design and Assign function.").
2. [Create record producers.](https://servicenow-prod.fluidtopics.net/~V9EfHXWjtF6OBDTLTDVzA "Create a record producer in the Telecommunications Network Inventory application. You can use this record producer to configure an activity in the playbook for the Design and Assign function.")
3. [Add input variables to the record producer](https://servicenow-prod.fluidtopics.net/P8dMXjHCoccuqy0LpYp7Ow "Create the variables for a record producer in the Telecommunications Network Inventory application. You can use these variables as input fields in an activity card in the playbook for the Design and Assign function.").
4. [Add variable set to the record producer](https://servicenow-prod.fluidtopics.net/jP5tsL8h7bE0StSuhx6C4Q "Add a variable set to a record producer in the Telecommunications Network Inventory application. You can use the variable set as input fields in an activity card for the Design and Assign function.").
5. [Create subflows](https://servicenow-prod.fluidtopics.net/Sgb_s7kXo2iSQwv4Zff0Bw "Create a subflow in the Workflow Studio. You can use this subflow to configure an activity in the playbook for the Design and Assign function.").
6. [Create request definitions](https://servicenow-prod.fluidtopics.net/cqim8AoAYN9G~CqWEfyS7A "Create a request definition and use it to configure the Design and Assign playbook. You can use this request definition to configure an activity for the Design and Assign playbook.").
7. [Create a playbook for design and assign function](https://servicenow-prod.fluidtopics.net/4ezp5YZxmV~dws3XNLk_rA "Create a playbook for the Design and Assign function in the Workflow Studio. You can use the playbook to design and assign a network service in the Telecommunications Network Inventory application.").
8. [Update the system property to configure the Design and Assign home page](https://servicenow-prod.fluidtopics.net/bv05xISE7AlPmb2AcDNKew "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.").
{#configure-playbooks-design-assign-function__ol_rqn_2xn_sdc}

On completing these activities, a UI action displays on the Design and Assign home page to launch the function. Select the UI action to launch your new Design and Assign function.
