Service Reporting is a defined process within the Continual Service Improvement (CSI) volume of ITIL version 3.
Service Reporting is a recognition of the large amounts of data and information that have to be gathered and summarized into meaningful reports. Perhaps the major challenge of Service Reporting is cross referencing.
Service Reporting cross referencing underpins the requirement to back up the evidence of a report. It is an important consideration when the report may include contracted third parties that operate under some form of agreement or contract.
