This legacy solution integrates with the Common Service Data Model (CSDM) framework to organize and manage key enterprise architecture entities. Show full answer Show less Starting from the Xanadu release, the legacy EA Home page has been deprecated for new users but remains accessible for existing users. New users should adopt the Enterprise Architecture Workspace Home page, which offers similar features and enhanced capabilities. ## Key Features * **Business Portfolio:** View and assess business capabilities and monitor business applications that support these capabilities, including those considered at risk. Capability mapping enables configuration item (CI) relationships between capabilities and applications. * **Information Portfolio:** Capture and link asset information as information objects associated with business applications. This portfolio includes data domains, information objects, database instances, and database catalogs, supporting a detailed application portfolio model. * **Application Portfolio:** Track business applications supporting capabilities and manage them effectively. Provides detailed information such as application category, manufacturer, and type, helping measure usability, cost, quality, performance, and risk. * **Technology Portfolio:** Utilize metrics for usability, cost, quality, performance, and risk to manage technology lifecycle management (TLM) in alignment with business applications. * **Integration with CSDM Tables:** EA leverages CSDM tables for unified planning and reporting across technologies, applications, and data entities, benefiting multiple ServiceNow products. ## Practical Considerations When implementing the CSDM framework with legacy EA, consider using CSDM 5.0 or later versions for updated guidance. For customers not yet using the latest CSDM, Rome documentation and staged implementation guides are recommended. Transitioning to the Enterprise Architecture Workspace is advised for new activations to access current features and improvements. ## Customer Benefits * Gain a clear, organized view of your organization's application landscape aligned with business capabilities and technology assets. * Identify and reduce redundancies to optimize budgetary expenditures. * Leverage CSDM-aligned data models for consistent enterprise architecture management and reporting. * Use capability mapping and portfolio management to support strategic planning and risk assessment. * Access integrated metrics for informed decision-making on application and technology lifecycle management. Use Enterprise Architecture (formerly APM) 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=zurich&pubname=zurich-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/bxN1~aS3UXgzdyPi8Xcunw "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 [Use capability map for planning - Legacy](https://www.servicenow.com/docs/VD4n81eFMFZz6GEfy3lMRg "Capability-based planning helps you to understand your business capabilities, and the business applications that support them, to achieve your business goals."). 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 [Manage the Technology Lifecycle Management (TLM) in Enterprise Architecture Workspace](https://www.servicenow.com/docs/LppfRlP2L83euEPNBMzIpw "Technology Lifecycle Management helps Enterprise Architects to manage 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 (formerly Application Portfolio Management) and CSDM tables - Legacy](https://www.servicenow.com/docs/ACyBbjsx8TbfWjHjQ6Fuuw)** Enterprise Architecture manages and uses CSDM tables. Several ServiceNow products benefit from and add value to Enterprise Architecture. * **[Enterprise Architecture (formerly Application Portfolio Management) use case - Legacy](https://www.servicenow.com/docs/UQY5zCkCvA_dXkkzZJATBQ)** Enterprise Architecture lets you define a single, version-agnostic entity that represents all instances, technologies, and data used for planning and reporting. * **[Enterprise Architecture (formerly Application Portfolio Management) considerations - Legacy](https://www.servicenow.com/docs/83~gwinjvcVSbfpg0yJViw)** 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=zurich&pubname=zurich-servicenow-platform&ft:locale=en-US)
