# Enterprise Architecture

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-   Inadequate performance because of outdated applications.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.

</table>## 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.

\[Omitted image "modeling-home.png"\] Alt text: 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.

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.
