The service request management practice supports the agreed quality of a service by handling all pre-defined, user-initiated service requests in an effective and user-friendly manner1. A service request is a request from a user or a user's authorized representative that initiates a service action that has been agreed as a normal part of service delivery2. A user wanting to know how to create a report is an example of a service request that can be handled by the service request management practice3. The other statements are not true because:
Incident management: The incident management practice restores normal service operation as quickly as possible after an interruption or reduction in quality of an IT service1. A user wanting to know how to create a report is not an incident, as it does not affect the availability or performance of a service2.
Service level management: The service level management practice sets clear business-based targets for service performance, so that the delivery of a service can be properly assessed, monitored, and managed against these targets1. This practice does not directly handle user requests, but it may define the service level agreements (SLAs) and service level objectives (SLOs) that apply to them2.
Change enablement: The change enablement practice maximizes the number of successful service and product changes by ensuring that risks have been properly assessed, authorized, and managed within a schedule1. A change is the addition, modification, or removal of anything that could have a direct or indirect effect on IT services2. A user wanting to know how to create a report is not a change, as it does not alter the configuration or functionality of a service component2.
