PART 2 CODEOF PRACTICE
1 Scope
ThispartofISOIIEC20000represents anindustryconsensusonquality standardsforITservicemanagemeRt
processes. These service management processes deliver the best possible service to meet a customer's
business needs within agreed resource levels, i.e. service that is professional, cost-effective and with risks
whichareunderstood andmanaged.
Thevarietyofterms usedforthe sameprocess,andbetweenprocesses andfunctionalgroups(andjobtitles)
can make the subject of service management confusing to the new manager. Failure to understand the
terminology can be a barrier to establishing effective processes.Understanding the terminology isa tangible
and significant benefit from ISOIIEC20000. This part of ISO/IEC20000 recommends that service providers
should adopt common terminology and a more consistent approach to service management. It gives a
common basis for improvements in services. It also provides a framework for use by suppliers of service
managementtools.
As a process based standard this code of practice is not intended for product assessment. However,
organizations developing service management tools, products and systems may use both the specification
andthecode of practice to help them develop tools,products andsystems that support bestpracticeservice
management.
Thispartof ISO/IEC20000 provides guidance toauditors andoffers assistance to serviceprovidersplannmg

servicemanagementplan.
Theseniorresponsibleowner's role should encompass resourcing for any continual or project based service
improvementactivities.
The senior responsible owner should be supported by a decision-taking group with sufficient authority to
definepolicyandtoenforceitsdecisions.

policies,plansandprocedures,andanyactivitiesrelatedtothese.
