Administrators can grant non-admin users the ability to develop global applications. Delegated Development is for the scoped applications only Reference:
The incorrect statement about Delegated Development in ServiceNow is that administrators can grant non-admin users the ability to develop global applications. Delegated Development allows administrators to grant non-admin users the ability to develop scoped applications, not global applications. Global applications are accessible by all other applications and do not have a namespace prefix. Scoped applications are isolated from other applications and have a unique namespace identifier. Delegated Development provides more granular control over the developer permissions, application resources, and data access.
