Service Reporting underpins many other practices included within the scope of the IT service management (ITSM) framework and service value system (SVS), with particular attention to Service Level Management (SLM) and Business Relationship Management (BRM).
A Service Reporting policy should define the reports that will be produced within the SVS together with their purpose and associated information.
The purpose of the measurement and reporting practice is to support good decision-making and continual improvement by decreasing uncertainty. This is achieved through the collection of relevant data and assessing it in appropriate contexts.
We have posted a documented service reporting policy template on our "Free ITSM Stuff" page, it can be found here ITSM Assist - Free ITSM Stuff
