They are increasingly being used to get various matters arranged, explained, and coordinated. The service desk has a major influence on user experience and how the service provider is perceived by the users.

The purpose of the problem management practice is to reduce the likelihood and impact of incidents by identifying actual and potential causes of incidents and managing workarounds and known errors1. Workarounds are temporary solutions that reduce or eliminate the impact of an incident or problem for which a full resolution is not yet available2. Known errors are problems that have a documented root cause and a workaround3.
