Process Separation in ServiceNow is also known as domain administration. This concept is part of the broader domain separation feature, which allows you to separate data, processes, and administrative tasks into logical groupings called domains. This is particularly useful for Managed Service Providers (MSPs) or large enterprises that need to manage multiple clients or departments within a single ServiceNow instance. Domain separation ensures that each domain can have its own set of data, processes, and administrative controls, providing a high level of customization and security.
