Service Support encompasses the support processes necessary to ensure service quality. These processes
manage problems and changes in the IT Infrastructure and are more control-oriented than technical.
The major processes in this area are:
SERVICE DESK OR HELP DESK
The Service Desk is the single point of focus for all IT services clients to request services and report problems. The service desk processes include tracking and escalation procedures. Also, the Service Desk is responsible for disseminating information to the organization regarding planned outages and the implementation of changes impacting production services.
The primary focus of Incident Management (IM) is the restoration of services following an incident. IM is primarily a reactive process; its processes guide diagnostic and escalation procedures required to restore services quickly. IM processes are tightly integrated with Help Desk, Problem Management, and Change Management processes.
The primary focus of Problem Management (PM) is to identify the causes of service issues and commission remedial work to prevent recurrences. PM processes are reactive in responding to incidents and proactive in detecting and preventing future events. Its methods are tightly integrated with Incident Management, Change Management and Availability Management (AM). Although AM performs the lead role in component failure and system outage analyses, PM performs an important function in obtaining data and analyzing it in support of the studies.
Configuration Management (CfM) processes to guide the collection, archiving and reporting of individual infrastructure component specifications. The Configuration Database is the single repository of configuration information for the enterprise. In addition to configuration information, the database contains information regarding the relationships and dependencies among infrastructure components.
CfM processes closely integrate with Change Management processes, because risk assessments must take into consideration any relationships and dependencies that may be affected by requested changes to production operations. CfM databases are also used by Capacity, Availability and IT Service Continuity Management processes to perform their work accurately.
Change Management (ChM), as the name implies, manages change being introduced into the IT infrastructure. ChM teams assess risks of individual variations, use the configuration information to identify dependencies and other impacted applications and systems, and after analyzing the data, authorize or deny change requests. The goal of ChM is to identify application code, functional and performance defects and intercept them before customers are impacted by them. Change Management teams are judged successful when changes are introduced into production operations without impact to business units or their customers.
Release Management is tightly integrated with Change Management. Release Management addresses large-scale changes to the environment such as installing a new database management system or managing widespread changes to a business application. As a result, Release Management is concerned with maintaining a large number of changes that will be introduced simultaneously into the production operating environment.
