The issues involved in, and criteria for, establishing the appropriate staffing model and levels are discussed in this section. They include the Service Desk Manager, Supervisor, Analysts and, in some organizations, these roles are complemented by business users ('Super Users') who provide first-line support.
The following factors should be considered when deciding staffing levels:
All these items should be carefully considered before making any decision on staffing levels. This should also be reflected in the levels of documentation required. Remember that the better the service, the more the business will use it. A number of tools are available to help determine the appropriate number of staff for the Service Desk. These workload modelling tools are dependent on detailed 'local knowledge' of the organization such as call volumes and patterns, service and user profiles, etc.
In order to have a good understanding of ITIL and the importance of configuration management, we first define what ITIL is: ITIL is literally a collection of documentation.
This documentation can help IT organizations implement the best practices. The documentation grows and grows as more successful techniques are documented and guidelines established for what can make others successful. The latest ITIL resources are published by the UK Office of Government Commerce (OGC).
Integrated service delivery refers to the need for Configuration Management, Change Management, Incident Management, Problem Management and Release Management processes that are linked together in a meaningful manner. For example, the process of releasing components to the live environment (the domain of Release Management) is also an issue for Configuration Management and Change Management whilst the Service Desk is primarily responsible for liaison between IT providers and the Users of services. This section highlights the links and the principal relationships between all the Service Management and other infrastructure management processes.
ITIL processes fall under Operational Layer or Tactical Layer, as follows:
|Operational Layer:||Configuration Management - Service Desk Management - Incident & Problem Management - Change Management - Release Management|
|Tactical Layer:||Service Level Management - Availability Management - Capacity Management - Continuity Management - Financial Management|
