Known Error:    A fault in a Configuration Item (CI) identified by the successful diagnosis of a Problem and for which a temporary work-around or a permanent solution has been identified.

The link between the Known Error (KE) and the CI may arise from local diagnosis of a Problem but may equally be derived from an external source of Known Errors. It is important that all relevant Known Errors are recorded in the Configuration Management Database (CMDB) although, clearly, the CMDB will not be the only source of Known Error data. Since many Problems will have multiple causes, the links between individual Problems and individual Known Errors might be complex..
