What is problem management?
The purpose of problem management is to reduce the likelihood and impact of incidents by identifying actual and potential causes of incidents, and managing workarounds and known errors.
Problems are related to incidents, but it is important to differentiate them in the way they are managed:
Incidents have an impact on users or business processes, and must be resolved so that normal business activity can take place.
Problems are the causes of incidents therefore they require investigation and analysis to identify the causes, develop workarounds, and recommend longer-term resolution. This reduces the number and impact of future incidents.
