    The workflow accelerates diagram creation, providing a clear overview of business application entities and their relationships. It is particularly valuable for enterprise architects aiming to enhance modeling efficiency and for other stakeholders seeking contextual understanding of architectural diagrams.

    Key Features

    • AI-driven Diagram Generation: Users interact with the Enterprise Architecture diagrams AI agent via the ServiceNow Otto panel to generate detailed business application hierarchy diagrams.
    • Summarization Capability: After diagram creation, the AI agent offers a summary that lists entities and explains relationships within the business application hierarchy.
    • Agentic Workflow Template: The workflow can be activated and customized by duplicating the template and adjusting instructions to meet specific organizational needs.
    • Role-Based Access Control: Requires the ServiceNow Otto Panel user role (nowassistpaneluser) to access the panel and the Enterprise Architecture user role (snapm.apmuser) to utilize the diagram generation workflow, with options to add more roles via access control configuration.
    • Easy Activation and Testing: Admins can enable the workflow via AI Agent Studio, configure security roles, and test workflows with example prompts through the ServiceNow Otto panel.

    Using the Workflow

    • Invoke the workflow by selecting the ServiceNow Otto icon within the instance and entering a prompt that includes the word “diagram” (e.g., “Create a diagram for XYZ business application”).
    • Follow customization steps if needed by duplicating and editing the agentic workflow template.
    • Administrators manage access and security roles to ensure appropriate user permissions for workflow execution.
    • Testing can be performed directly within AI Agent Studio to validate the workflow’s behavior before production use.

    Benefits for ServiceNow Customers

    • Speeds up enterprise architecture diagram creation, reducing manual effort and time.
    • Enables clearer communication and understanding of business application structures across technical and non-technical teams.
    • Provides flexibility to tailor the AI agentic workflow to specific organizational requirements.
    • Ensures secure and role-based access to sensitive enterprise architecture functions.

    Use the Enterprise architecture diagrams AI agent to generate Enterprise Modeling and Visualization diagrams for business applications hierarchy and summarize them.

    Note:
    Depending on your license, you will have access to certain application features, generative AI skills, agentic workflows, and AI agents. For more information, see .

    Generate enterprise architecture diagram overview

    Use the Generate enterprise architecture diagram agentic workflow to create enterprise architecture diagrams for business applications hierarchy, through a conversation with an AI agent in the ServiceNow Otto panel. This agentic workflow accelerates the time to value for enterprise architects while building business hierarchy diagrams. It also enables non-enterprise architects to understand the context of an architectural diagram.

    After generating the diagram, the AI agent suggests summarizing the created business application hierarchy diagram, listing all entities in the diagram and describing the relationship between them.

    You can activate the agentic workflow template by setting the display settings to include the ServiceNow Otto panel. To change instructions for this agentic workflow, duplicate it and adjust the settings to suit your specific needs. Then activate the duplicated version instead. For information on how to duplicate a agentic workflow, see duplicate the agentic workflow.

    Important:
    • The ServiceNow Otto Panel user role (now_assist_panel_user) is required to view the ServiceNow Otto panel on your instance.
    • The Enterprise Architecture user role (sn_apm.apm_user) is required to use the Generate enterprise architecture diagram agentic workflow.

    Role masking

    Required role: sn_apm.apm_user.
