    Summary of Enterprise Architecture (formerly Application Portfolio Management)

    ServiceNow® Enterprise Architecture (EA) integrates strategic and operational teams to help organizations align IT investments with business objectives. It acts as a decision engine by managing business capabilities, application portfolios, information, and technology portfolios. EA supports enterprise architects in strategic planning, application rationalization, and transformation efforts, enabling informed decisions on whether to invest in, sustain, migrate, or retire applications based on business needs and goals.

    EA addresses common business challenges such as redundant applications, rising maintenance costs, demands for upgrades, conflicts between legacy and vendor applications, and outdated performance. By leveraging EA processes, organizations can optimize costs and improve business functions efficiently.

    Key Features

    • Enterprise Modeling and Visualization: Create and maintain architecture diagrams aligned with standards like CSDM, ArchiMate, and AWS. Model applications, capabilities, processes, and cloud architectures to visualize current and future states, supporting stakeholder understanding, impact assessment, and change planning.
    • Architecture Analyzer: Explore and analyze architecture relationships dynamically without custom diagrams. Understand dependencies and impacts across applications, services, and infrastructure to aid collaboration and decision-making.
    • Rationalization of Business Applications: Evaluate applications using standardized indicators such as cost, risk, value, and technical debt. Use interactive bubble charts and list views to identify redundancies and prioritize actions for modernization, investment, or retirement decisions over time.
    • Publishing Center: Centralize control of publishing workflows for Technology Reference Model (TRM) catalogs and technology standards, ensuring consistent governance and easy sharing of architecture outputs.
    • Data Certification: Maintain the accuracy, completeness, and reliability of enterprise architecture data by defining certification policies, running scheduled or on-demand certifications, and tracking their status to enhance trustworthiness for reporting and decision-making.
    • Enterprise Architecture Workspace: Provides a unified interface for managing tasks, monitoring portfolio health, and gaining insights. It supports managing Technology Portfolio Management (TPM), application total cost of ownership (TCO), and lifecycle timelines.
    • Now Assist for Enterprise Architecture: Facilitates summarization of Architectural Decision Records (ADR) and gathers insights into business applications to support architects within the EA Workspace.

    Benefits and Practical Use

    ServiceNow Enterprise Architecture enables customers to unify their IT and business strategies by providing clear visualizations and actionable insights into their application and technology landscapes. Customers can expect improved decision-making capabilities regarding application investments, consolidation, and modernization. The solution helps reduce redundancies, control costs, and ensure data integrity for architecture portfolios, ultimately supporting smoother business transformation initiatives.

    By using EA’s modeling, analysis, and certification features, enterprise architects can confidently manage complex IT environments, communicate architecture changes effectively, and govern architectural standards across the organization.

    The ServiceNow® Enterprise Architecture unites strategic and operational teams, enabling organizations to achieve their business objectives. It serves as a powerful decision engine, combining robust modeling with the management of business capabilities, application portfolios, information portfolios, and technology portfolios.

    Enterprise Architecture helps enterprise architects manage business applications as part of an enterprise architecture practice focused on strategic planning, rationalization, and transformation.

    Enterprise Architecture helps you decide whether to invest, sustain, or replace applications based on the business need aligned toward the organization goal.

    You can address business challenges such as:
    • Redundant applications for similar functions.
    • Increasing cost of owning and maintaining applications.
    • Increasing demand to upgrade the existing applications for new functions.
    • Conflict between in-house legacy applications and that of the vendors.
    • Inadequate performance because of outdated applications.

    Overcome these challenges, improve business functions in an efficient and smooth manner, and optimize cost with these Enterprise Architecture processes.

    Enterprise Modeling and Visualization

    Create diagrams and model the future state of your IT and its relationship to the business landscape.

    Rationalization of business applications

    Rationalize all business applications in a category and decide whether to invest, sustain, migrate, or retire an application.

    Data Certification

    Ensure the accuracy, completeness, and reliability of critical enterprise architecture data.

    Enterprise Modeling and Visualization in the EA Workspace

    Create diagrams and model the current and future state of your architecture and its relationship to the business landscape.

    Modeling page

    Enterprise Modeling and Visualization in the Enterprise Architecture Workspace enables enterprise architects to:
    • Create architecture diagrams using industry‑aligned standards such as CSDM, ArchiMate, and AWS
    • Model applications, business capabilities, processes, value streams, and cloud architectures
    • Maintain architectural context by associating diagrams with applications, capabilities, and artifacts
    • Generate architecture documents directly from diagrams for review, sharing, and approval
    These visual models help stakeholders understand dependencies, assess impact, and plan change with confidence.

    Architecture Analyzer

    Visually explore and analyze architecture relationships without creating or maintaining custom diagrams.

    Architecture Analyzer provides a dynamic canvas to:
    • Analyze relationships across applications, services, infrastructure, and Enterprise Architecture extended entities
    • Understand dependencies and assess the impact of architectural changes
    • Explore architecture perspectives interactively to support collaboration and decision‑making
    Architecture Analyzer helps architects quickly assess complex landscapes and communicate insights effectively.

    Rationalization of business applications

    Evaluate and rationalize business applications to support modernization and investment decisions.

    Bubble chart viewList view

    Application Rationalization enables you to:
    • Assess applications using standardized indicators such as cost, risk, value, and technical debt
    • Compare applications using interactive bubble charts and list views
    • Identify redundancy and prioritize actions to invest, sustain, migrate, or retire applications
    • Apply filters and fiscal periods to analyze application performance over time
    These insights support data‑driven decisions across large application portfolios.

    Bubble charts are interactive graphs that position applications in different quadrants, based on their indicator scores. Based on the position of the business application in the quadrants, enterprise architects can take decisions to invest in, sustain, migrate, or retire the business applications.

    The List view enables you to see high-level information on all your business applications and all the indicator scores that are attached to them.

    Publishing Center in Enterprise Architecture Workspace

    Control and manage publishing workflows from a centralized location.

    The publishing center enables you to:
    • Publish Technology Reference Model (TRM) catalogs to a knowledge base
    • Share approved technology standards across the organization
    • Monitor publishing status and view publishing history
    • Govern architecture outputs with consistent publishing processes
    Publishing center simplifies how architectural standards and insights are shared and consumed.

    Data Certification in Enterprise Architecture Workspace

    Ensure the accuracy, completeness, and reliability of critical enterprise architecture data.

    With data certification, you can:
    • Define certification policies directly in the Enterprise Architecture Workspace
    • Run certifications on demand or on a schedule
    • Track certification status and identify overdue or failed certifications
    • Improve trust in architecture data used for reporting and decision‑making
    Data certification helps maintain high‑quality data across architecture portfolios.
