Service Support and Service Delivery by Anticlue

Below is a quick memory aid for the functions and processes involved in ITIL service support and service delivery.

Service support
Service support describes the day-to-day operation and support of IT services. It includes the service desk function as well as the following five processes:

• Service desk – The service desk function is the single point of contact between users and IT service management. Tasks include handling incidents and requests, and providing an interface for other ITSM processes.
• Incident management – Incident management's goal is to restore service operation as quickly as possible with minimal disruption to users.
• Problem management – Problem management is a process designed to minimize the adverse effects of incidents and problems caused by infrastructure errors. It also seeks to proactively prevent the recurrence of these incidents and problems.
• Configuration management – Configuration management is a process of identifying and defining configuration items within a system. It also involves monitoring the status of these items, processing requests for change, and verifying the completeness and correctness of configuration items.
• Change management – Change management is a process of controlling changes within IT services or systems, with proper approval and minimal disruptions.
• Release management – Release management is the process of introducing new or changed configuration items to the infrastructure. These configuration items have been approved by change management, tested, and determined to be ready for implementation.

Service delivery
Service delivery describes the long-term planning and improvement of IT service provision. It addresses the following five processes:

• Service level management – Service level management negotiates and agrees to service requirements as defined by the customer and agreed to by IT within the service level agreement. Then it monitors, measures, and reports on the achieved service levels.
• Financial management for IT services – This is a process concerned with cost awareness; more specifically the identification, allocation, forecasting, and monitoring of costs associated with IT services.
• Capacity management – ensures the projected business needs will be met in a cost-effective and timely manner. It also ensures the infrastructure can handle new technology. Capacity entails storage, facilities, networking capabilities, and people.
• IT service continuity management – ensures that the proper and required IT technical and service facilities can be recovered in the agreed upon and required time frame following a disruption to the business.
• Availability management – ensures services are available when and at the level the customer requires them, as defined by the service level agreement.
