This paper presents the improvement of the
implementation of ISO/IEC 20000 Edition 2 standard by
comparison with the ITIL V3 set of best practices for
implementing an IP multimedia subsystem of Telecom
operator. In this paper implementation of IMS system has
been done by using ISO/IEC 20000 Edition 2
recommendations and service lifecycle with its comparisons
with ITIL V3 recommendations and service lifecycle. The
aim of this paper is to present the improved service lifecycle
of ISO/IEC 20000 Edition 2 standard through comparative
analysis with ITIL V3 implementation of IMS system.
Improved implementation of ISO/IEC 20000 Edition 2
standard will be shown in the form of new processes that are
added to existing service lifecycle and are evaluated with Key
Performance Indicators (KPIs), Key process activities and
missing activities that will be singled out as a separate
processes.
Keywords — IMS system, ITIL V3, KPI, ISO/IEC 20000
Edition 2, CSF, Key activities.
