1 Scope
The present document investigates the management of End to End (E2E) services across Management Domains (MDs).
It defines the management processes during the lifecycle of E2E services (covering onboarding processes, fulfilment
processes and assurance processes) and describes the interactions between E2E service management domain and
management domains during these processes.
Furthermore, it maps the management services used in the management processes to the northbound interfaces of
selected technology domains and references the underlying specifications of these interfaces. These mappings enable
the automation of lifecycle management across domains.
