7.4.1 Request models
Some Service Requests will occur frequently and will
require handling in a consistent manner in order to meet
agreed service levels. To assist this, many organizations will
wish to create pre-defined Service Request models (which
typically include some form of pre-approval by Change
Management). This is similar in concept to the idea of
Incident models, but applied to Service Requests.
Most requests will be triggered through either a user
calling the Service Desk or a user completing some form
of self-help web-based input screen to make their request.
The latter will often involve a selection from a portfolio of
available request types.
