In paper [2], authors have proposed a new maturity
model to assess an ITIL implementation and provide a
roadmap for improvement based on priorities,
dependencies, and guidelines. They have demonstrated a
practical application of the proposed model with a
questionnaire to assess the ITIL Incident Management
process that was evaluated in two real-world
organizations. Very interesting paper is also [3] in which
the design and implementation of IMS system has been
done by using ITIL V3 recommendations. Results of this
implemented system have shown that the percentage of the
successful implemented IMS tests by using ITIL V3
recommendations is 98%. This result shows that the
implemented IMS model is suitable for the release into a
production. Paper [4] describes differences between these
ITIL 2007 and ITIL 2011 in the implementation of the IP
Multimedia Subsystem (IMS system) in one Telecom
Operator in Bosnia and Herzegovina. The result of the
paper is also a set of suggestions for the future ITIL V3
improvement. Finally, paper [5] has showed that as IT
service providers are adopting more comprehensive
approaches towards IT service management (ITSM), they
increasingly need to rely on ITSM software solutions in
their day-to-day operations. Without any standardized
information model for ITSM processes, efficient and
integrated ITSM will remain a vision. While in the
telecommunications sector, a lot of work has been invested
into developing the shared information/data model (SID),
a companion model for the industry-specific process
framework enhanced telecom operations map (eTOM), no
equivalent for the more general process frameworks of
ITIL and ISO/IEC 20000 is in sight. This paper introduces
an approach towards an information model for ITSM
processes. The presented method leverages work done for
SID, by adapting and complementing SID concepts and
content to produce an information model compliant to
ISO/IEC 20000 requirements and ITIL recommendations.
This paper is the introduction into research covered in this
paper. The research covered is the continuous of previous
research papers in improvement of actual version of ITIL,
but also the first paper which gives a new model of ITIL
framework from ISO/IEC 20000 standard
