The model consists of 5 maturity levels, which contains
key process areas. For an organization to reside on a
certain maturity level, it needs to implement all of the
key processes for that level and the those of lower
levels.
Levels: 1,
2, 3,
4, 5
1- Initial Level
- The IT service delivery process is characterized
as ad-hoc and occasionally even chaotic. Few
processes are defined and success depends on
individual effort an heroics
2 - Repeatable Level
- Basic service management processes are
established. The necessary discipline is in place to
repeat earlier successes on a similar services with
similar service levels
3 - Defined Level
- The IT service processes are documented,
standardised, and integrated into standard service
processes. All services are delivered using
approved, tailored versions of the organisation’s
standard service processes
4 - Managed Level
- Detailed measurements of the IT service delivery
process and service quality are collected. Both the
service processes and the delivered services are
quantitatively understood and controlled
5 - Optimizing Level
- Continuous process improvement is enabled by
quantitative feedback from the processes and from
piloting ideas and technologies
Comparison of ITSCMM to ITIL
- Both are aimed at the domain of IT service
management
- ITIL is organised as a framework of best
practices organised by different processes
- ITSCMM is organised as an ordered set of key
process areas, that provide an improvement path
- ITIL provides more detail on process
implementation and process activities
- ITIL defines IT services as services delivered
by IT, whereas ITSCMM defines IT services as services
delivered by one party to another that maintain,
operate or improve the information technology
