This capability allows for embedding business logic through if-then conditions that evaluate input data at runtime and return results based on matched criteria. Since the Washington DC release, Decision Builder is integrated into Workflow Studio, providing a unified environment to author and monitor processes, flows, playbooks, actions, and decision tables. Show full answer Show less Note that after Workflow Studio decision tables installation, creation and modification of decision tables must be done exclusively in Workflow Studio; the classic environment no longer supports these tasks. ## Key Features * Create inputs that pull data at runtime from existing records, external sources, or hard-coded values. * Construct and modify decision rules with an intuitive interface. * Reorder evaluation criteria to optimize decision outcomes. * Delegated development capability enables non-admin users with delegated roles to create and manage decision tables, improving workload distribution. * Integration with ServiceNow AI Platform applications, such as App Engine Studio, allows developers to build and manage decision tables within a centralized app development environment. ## Benefits * Facilitates building complex decision logic easily without modifying application code. * Supports rapid adaptation to changing business requirements by updating decision rules directly. * Enhances efficiency through reusable decision logic across multiple applications. * Enables dynamic evaluation of data from diverse sources including ServiceNow records and external inputs. ## Getting Started and Support ServiceNow customers can begin by exploring decision table concepts and configuring necessary environments and user access within Workflow Studio. Detailed references on decision table properties and domain separation features are available. For assistance, customers should contact their Customer Admin for user management and system operations or utilize ServiceNow Community resources, the Known Error Portal, and Customer Service and Support channels. Decision tables in Workflow Studio enable developers to decouple decision logic from their code by creating and maintaining decision rules. ## Demo {#decision-designer-overview__section_uq5_fty_ryb} For an in-depth review and demo of decision table features and benefits, see [Decision Builder Testing and Publishing \| Creator Toolbox-ServiceNow](https://youtu.be/wOZs0Qew7t8). ## Announcements {#decision-designer-overview__section_i1w_l2x_11c} * As of the Washington DC release, Decision Builder is now part of Workflow Studio. Workflow Studio gives you a streamlined way to author, configure, and monitor processes, flows, subflows, playbooks, actions, and decision tables in one place. * The core Decision Builder feature is still available with the ServiceNow AI Platform® by default, but the latest updates are available for download through the Workflow Studio application in the ServiceNow® Store. * For more information about this update, see the Washington DC Decision Builder release notes. {#decision-designer-overview__ul_bgw_42x_11c} ## Get started {#decision-designer-overview__section_o4v_mvz_nyb} |-|-| | [ExploreLearn about decision table concepts and features](https://www.servicenow.com/docs/F3XK4cmAeQoDNcsovX6lZw "Learn how to create and maintain decision tables in Workflow Studio for use in flows, subflows, playbooks, and anywhere on the ServiceNow AI Platform where you write code.") | [ConfigureConfigure environments, tools, and user access for decision tables in Workflow Studio](https://www.servicenow.com/docs/im_2jrrvMqWovADtno4_Og#configuring-decision-builder "Workflow Studio is installed automatically with each family upgrade.

You can no longer create or modify decision tables in the classic environment. Workflow Studio provides an intuitive interface to create and manage decision tables, which store sets of decision rules. Decision tables embed business logic into a series of if-then decision rules. Decision tables read data from inputs and evaluate the data according to specified conditions. When all the conditions for a decision rule are met, the decision table returns one or more results. Administrators can use the delegated development capability to manage workload efficiently by assigning the delegated development role to developers or non-admin users. A delegated developer has more permissions than a user, but less than an admin. Non-admin designated users can create and manage decision tables at the application level. For more information, see [Delegated development](https://www.servicenow.com/docs/access?context=c_DelegatedDevelopment&version=brazil&pubname=brazil-application-development&ft:locale=en-US). Decision tables in Workflow Studio enable you to do the following: * Create inputs that read data at runtime from existing records, external data sources, or hard-coded values. * Create and modify decision rules. * Change the order of evaluation criteria to optimize results. {#decision-designer-overview__ul_xkd_dkh_5qb} ## Benefits {#decision-designer-overview__section_erv_mkh_5qb} Decision tables in Workflow Studio provide the following benefits: * Build complex decisions easily with decision tables. * Meet changing business requirements and quickly update decisions by modifying only the decision logic and not the application code. * Increase efficiency by reusing decision logic across multiple applications. * Evaluate data at runtime from multiple sources, including existing ServiceNow records and data from external sources. {#decision-designer-overview__ul_c11_4kh_5qb} ## Workflow Studio integration with other applications {#decision-designer-overview__section_umn_5yl_vsb} Extend the capabilities of decision tables in Workflow Studio by integrating with applications in the ServiceNow AI Platform® suite.{#decision-designer-overview__table_b4b_c2m_vsb__entry__3} | Application | Description | Reference | |-|-|-| | [App Engine Studio](https://www.servicenow.com/docs/access?context=aes-overview&version=brazil&pubname=brazil-application-development&ft:locale=en-US) | * App Engine Studio (AES) provides an Integrated Development Environment (IDE) application-like interface for app developers to build custom applications in one centralized location while maintaining your organization's brand and application development standards. * AES users can create decision tables using an AES wizard and access existing decision tables for their applications without leaving AES. {#decision-designer-overview__ul_t2l_xjf_xsb} | See [Add a decision](https://www.servicenow.com/docs/access?context=add-automation&version=brazil&pubname=brazil-application-development&ft:locale=en-US) in App Engine Studio. | [Table 1.
