ServiceNow recommends a domain separation approach that maximizes the use of standard configurations while minimizing custom configurations. This approach ensures maintainability, scalability, and ease of upgrades. The recommended approach is:

•80% or more Standard: Utilizing out-of-the-box (OOTB) configurations as much as possible to leverage ServiceNow’s built-in capabilities and best practices.

•15% or more data-driven: Using data-driven configurations to adapt to specific business needs without extensive custom coding.

•Less than 5% Configuration: Minimizing custom configurations to reduce complexity and potential issues during upgrades.

This strategy aligns with ServiceNow’s best practices for domain separation, ensuring that the system remains robust and easier to manage.

1: ServiceNow Domain Separation Best Practices 2: Understanding Domain Separation in ServiceNow

In ServiceNow, domain separation allows for the segregation of data, processes, and administrative tasks into logical groupings called domains. Within these domains, you can create specific business logic that is unique to each domain. The business logic that can be created in a domain includes:

•Business Rules: These are server-side scripts that execute when a record is displayed, inserted, updated, or deleted, or when a table is queried. Business rules can be used to apply business logic across all applications within a domain1.

•Email Notifications: These can be configured to respond to various events within a domain and can be set up to target users within specific domains. This allows for domain-specific communication strategies2.

•Script Includes: These are reusable server-side scripts that can be included in other scripts. Script includes can be used to store common functions or classes that are applicable to the domain-specific business logic3.

UI Policies and UI Scripts, while they can be part of the user interface customization in a domain-separated environment, are not considered business logic in the context of this question. UI Policies dynamically change information on a form and UI Scripts can add JavaScript to forms. However, they do not define the underlying business logic like Business Rules, Email Notifications, and Script Includes do.

For further details and best practices regarding domain separation and the creation of business logic within domains, you can refer to the ServiceNow documentation and resources provided23.

When an administrator attempts to modify a policy, application, or module that belongs to another domain higher in the hierarchy, the system automatically sets the sys_domain_owner field. This field ensures that the ownership of the record is correctly attributed to the domain that originally created or owns the record, maintaining the integrity and separation of data across different domains.
