Problem Management - Problem detection
It is likely that multiple ways of detecting problems will exist in all organizations. These will include:
- Suspicion or detection of a cause of one or more incidents by the Service Desk, resulting in a Problem Record being raised – the desk may have resolved the incident but has not determined a definitive cause and suspects that it is likely to recur, so will raise a Problem Record to allow the underlying cause to be resolved. Alternatively, it may be immediately obvious from the outset that an incident, or incidents, has been caused by a major problem, so a Problem Record will be raised without delay.
- Analysis of an incident by a technical support group which reveals that an underlying problem exists, or is likely to exist.
- Automated detection of an infrastructure or application fault, using event/alert tools automatically to raise an incident which may reveal the need for a Problem Record.
- A notification from a supplier or contractor that a problem exists that has to be resolved.
- Analysis of incidents as part of proactive Problem Management - resulting in the need to raise a Problem Record so that the underlying fault can be investigated further.
Frequent and regular analysis of incident and problem data must be performed to identify any trends as they become discernible. This will require meaningful and detailed categorization of incidents/problems and regular reporting of patterns and areas of high occurrence. 'Top ten' reporting, with drill-down capabilities to lower levels, is useful in identifying trends.
Further details of how detected trends should be handled are included in the Continual Service Improvement publication.
Other ITIL Processes
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 |
