    Summary of Exploring Decision Tables

    Decision tables in Workflow Studio allow developers to separate decision logic from code, making it easier to create and maintain decision rules. As of the Washington DC release, Decision Builder is integrated into Workflow Studio, providing a unified platform for managing processes, flows, and decision tables.

    Key Features

    • Intuitive Interface: Workflow Studio offers a user-friendly environment for creating and managing decision tables that store decision rules.
    • Runtime Data Evaluation: Decision tables can read data from existing records, external sources, or hard-coded values to evaluate conditions and return results.
    • Delegated Development: Administrators can assign roles to developers, allowing non-admin users to create and manage decision tables.
    • Integration with Applications: Decision tables can be integrated with other applications within the ServiceNow AI Platform, enhancing functionality.

    Key Outcomes

    With decision tables in Workflow Studio, organizations can:

    • Quickly adapt to changing business needs by modifying decision logic without altering application code.
    • Improve efficiency by reusing decision logic across multiple applications.
    • Streamline the process of building complex decision-making capabilities.

    For additional support, customers can contact their Customer Admin or refer to the ServiceNow Community for further assistance.

    Decision tables in Workflow Studio enable developers to decouple decision logic from their code by creating and maintaining decision rules.

    Announcements

    • 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.

    Features

    Note:
    After you install Workflow Studio decision tables, you can only access decision tables previously created in the classic environment through Workflow Studio. 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.

    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.

    Benefits

    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.

    Workflow Studio integration with other applications

    Extend the capabilities of decision tables in Workflow Studio by integrating with applications in the ServiceNow AI Platform® suite.

    Application Description Reference
    App Engine Studio
    • 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.
