It integrates closely with the Common Service Data Model (CSDM) framework to unify key entities for effective planning and reporting. EA supports a holistic understanding of business capabilities, application portfolios, information assets, and technology metrics to help you manage and optimize your IT landscape.

Facilitates management aligned with organizational goals. * **Technology Portfolio:** Measures usability, cost, quality, performance, and risk of applications through metrics, supporting lifecycle management of technology assets. * **Enterprise Architecture and CSDM tables:** EA leverages and manages CSDM tables, benefiting multiple ServiceNow products by providing a unified data model for architecture insights. ## Practical Implications for ServiceNow Customers By using Enterprise Architecture with the CSDM framework, customers can: * Gain a unified, version-agnostic view of all application instances, technologies, and data to improve planning and reporting accuracy. * Identify redundancies and assess risks in business applications and capabilities to optimize investments and reduce costs. * Leverage detailed portfolios to manage information assets and technology lifecycles effectively. * Transition smoothly from legacy EA interfaces to the enhanced Enterprise Architecture Workspace for ongoing management. Customers implementing the CSDM framework should consider these EA features to maximize value and ensure alignment with organizational objectives. Use Enterprise Architecture to gain a comprehensive understanding of your organization's applications so you can identify redundancies and decrease budgetary costs. The goal of this product view is to help you to understand how Enterprise Architecture key entities work with the core CSDM framework. Note: If you do not use CSDM 5.0 or later versions, see the Rome documentation for CSDM. For implementing CSDM framework, see [Implementing the CSDM framework in stages](https://www.servicenow.com/docs/access?context=csdm-implementation-stages&version=australia&pubname=australia-servicenow-platform&ft:locale=en-US). ## Enterprise Architecture home page {#apm-use-case-product-view__section_hk2_kvx_1wb} Important: Starting with the Xanadu release, the legacy Enterprise Architecture (formerly Application Portfolio Management) Home page has been deprecated. However, if you are an existing user of Enterprise Architecture (formerly Application Portfolio Management), you can still view the legacy Home page. If you are a new activation user, the legacy Home page is not available. You can leverage the same features provided by the Application Portfolio Management Home page by using the Enterprise Architecture Workspace Home page. To learn more about Enterprise Architecture Workspace, see [Enterprise Architecture Workspace](https://www.servicenow.com/docs/1KfJyrnGagOWkYrcqEnnyg "The Enterprise Architecture Workspace (EA Workspace) is part of the Enterprise Architecture application. It provides an interactive interface for enterprise architects to manage tasks, gain insights, and monitor portfolio health."). The Enterprise Architecture home page organizes many of the CSDM tables used by Enterprise Architecture. Business Portfolio : View the number of defined business capabilities that have been or will be assessed, and the number of business applications that support capabilities but are at-risk. For more information about using capability mapping to establish a configuration item (CI) relationship between the business capability and the business applications, see [Exploring a business portfolio](https://www.servicenow.com/docs/9W856Vsk7WXron5pwpUKPg "As an Enterprise Architect, view the capability hierarchy, manage capabilities, and assign business applications to the capabilities."). Information Portfolio : Capture the asset information as information objects. You can connect the information object to your business applications to create an application portfolio that you can use at any time. The information portfolio links to the following data: * Data Domains: Total number of records in the Data Domain table \[sn_apm_data_domain\]. * Information Objects: Total number of records in the Information Object table \[cmdb_ci_information_object\]. * Database Instances: Total number of records in the Database Instance table \[cmdb_ci_db_instance\]. * Database Catalogs: Total number of records in the Database Catalog table \[cmdb_ci_db_catalog\]. {#apm-use-case-product-view__ul_yy4_kgc_smb} For more information about the information portfolio and the information portfolio model, see \[product\]. Application Portfolio : Track the applications that support your business capabilities and effectively manage them to meet the goals of your organization. The portfolio provides a list of applications with information such as their category, manufacturer, and type. Select Applications to navigate to the list view of business applications in your organization. For more information about measuring the usability, cost, quality, performance, and risk of applications, see \[product\]. Technology Portfolio : Use metrics to measure the usability, cost, quality, performance, and risk of applications. For more information about technology portfolio management and how it relates to business applications, see [Exploring Technology Lifecycle Management (TLM) in Enterprise Architecture Workspace](https://www.servicenow.com/docs/BGLPRnuND_K7lEKsDt_4xQ "Technology Lifecycle Management helps Enterprise Architects to track technology life-cycle risks and technology life-cycle exceptions. Enterprise Architects can evaluate all their business applications and application services by accessing the discovered technologies and auditing information in the Enterprise Architecture Workspace."). * **[Enterprise Architecture and CSDM tables](https://www.servicenow.com/docs/f0MQkLLr3DTnCESNSBUGhw)** Enterprise Architecture manages and uses CSDM tables. Several ServiceNow products benefit from and add value to Enterprise Architecture. * **[Enterprise Architecture use case](https://www.servicenow.com/docs/AsY5mdh2bS8ejh_5wF~VMQ)** Enterprise Architecture lets you define a single, version-agnostic entity that represents all instances, technologies, and data used for planning and reporting. * **[Enterprise Architecture considerations](https://www.servicenow.com/docs/8rg67IB5uomVxRvfUg0LHQ)** Consider these points while implementing the CSDM framework. **Related topics** * [Exploring the CSDM model](https://www.servicenow.com/docs/access?context=csdm-content-frame-exploring&version=australia&pubname=australia-servicenow-platform&ft:locale=en-US)
