## Summary of Configure a Design and Assign function example

This example outlines the process of creating and configuring a playbook to design and assign a network service in the Telecommunications Network Inventory application.
It focuses on fulfilling customer requests for Optical Network Terminals (ONT) by capturing necessary details and automating tasks through a structured playbook workflow.
Show full answer Show less  

## Key Features

* **Setup Network Service:** Collects service details for the design request.
* **Capture ONT Details:** Gathers ONT site and equipment template information.
* **Review and Submit:** Allows for reviewing details and creating ONT devices based on templates.
* **Automation:** Automates creation of change requests and tasks, streamlining the process of instantiating equipment.

## Prerequisites

Before creating a playbook, ensure you have configured the following:

* **Change Model:** Create a model named "Network Service Automated Flow" with specific states (Design in progress, Design complete, Closed) and transitions.
* **Record Producer:** Establish a record producer named "Capture ONT Details" to collect ONT input details.
* **Subflow and Request Definition:** Configure a subflow and a request definition to facilitate the capture and processing of ONT details.

## Key Outcomes

Utilizing the playbook as a playbook agent allows you to fulfill customer orders effectively. By following the structured steps, you can design and assign network services, creating ONT devices based on specified templates and sites. This process enhances efficiency and accuracy in service delivery.  
This example demonstrates how you can create and configure a playbook to design and assign a network service in the Telecommunications Network Inventory application.

## Example overview {#configure-design-assign-playbook-use-case__section_wqp_4hb_tdc}

Consider you have an order requests from a customer to fulfill a network service that must create Optical Network Terminals (ONT) for a specified location. To design and assign this network service, you must capture the ONT details
such as an ONT site and equipment template details. By creating and configuring a playbook for the Design and Assign function, you can automate these tasks by following step-by-step guidance for designing the network service.  
As a playbook admin, you create and configure the playbook to design and assign your inventory for the network service. The playbook contains the following activities to create the ONT device.

1. Setup Network Service - Collects service details of your design request.
2. Capture ONT Details - Capture the ONT site and inventory template details to instantiate the equipment.
3. Review and Submit - You review the activity details and creates the ONT devices for the specific location according to the template.
{#configure-design-assign-playbook-use-case__ol_obm_xlc_tdc}  
As a part of this playbook workflow, you automate the following.

* Creates a change request for the ONT design.
* Creates change tasks for the activities such as capturing ONT details.
* Execute the change tasks to instantiate the equipment using an inventory template.
{#configure-design-assign-playbook-use-case__ul_vvw_bwf_tdc}

As a playbook agent, you can fulfill your customer orders and requests for the network service by using this Design and Assign function.

The following example shows the playbook that you created and configured in the Workflow Studio.Figure 1. Example of the playbook in Workflow Studio

## Adding playbook to home page {#configure-design-assign-playbook-use-case__section_qm4_wch_tdc}

You add the sys_id of the Network Service Automated Flow Change model in the `sn_ni_ws.tni_design_assign_chg_models` record. To learn more about the detailed steps, see [Update 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.").

## Using a Design and Assign function {#configure-design-assign-playbook-use-case__section_sp5_rlc_tdc}

As an agent, you use the playbook for the Design and Assign function to fulfill the requirement of the network service by following the steps.

1. Navigate to WorkspacesNetwork Inventory Workspace.
2. Select the design and assign icon (![Design and Assign Icon]()) to open the Design and Assign home page.
3. On the Design Assign home page, select NewNetwork Service Automated Flow.
4. Complete the activities on the playbook to design and assign your network service.
{#configure-design-assign-playbook-use-case__ol_cjn_x2h_tdc}

This process creates an ONT device based on the template and site that you selected in the playbook activity.

The following example is the Design and Assign function that you created.
