Which process is responsible for managing all service requests from users?

'Change fulfilment' is not a standard ITIL process name; change management handles authorized changes to infrastructure but is not responsible for routine user service requests.

Incident management handles unplanned interruptions or reductions in quality of IT services, not routine user-initiated service requests.

Request fulfillment manages the full lifecycle of all service requests, which are pre-defined, low-risk actions users ask IT to perform - such as password resets or software installations. It provides a standardized channel separate from incident management to handle routine user requests efficiently and consistently.

Event management monitors and processes events generated by IT infrastructure components, not user-submitted service requests.
