service measurement plays an important role in IT service
management that is one of the subfields of Services
Computing science [1]. Many IT service organizations consider
the measurement of IT service management processes,
especially service support processes, as a difficult task.
Difficulties are mainly due to the following four reasons:
1) IT organizations do not have a structured approach for
measuring IT services and service management processes,
2) tools used by service support teams do not enable
effective measurement, 3) IT service management standards
and frameworks do not provide practical examples how
to measure support processes, and 4) there are too many
options what to measure in service management.
