A known error has been created after diagnosis of a problem was complete but before a workaround has been found. Is this a valid approach?

ITIL problem management guidance states that a known error record may be raised at any time it is useful to record the diagnostic information, even if diagnosis is incomplete or no workaround has yet been found. Creating the record early makes the known information available to incident management teams so they can reduce resolution time on future occurrences of the same issue. Waiting for a workaround before creating the record would unnecessarily delay the sharing of partial but valuable diagnostic knowledge.

ITIL does not require a known error to exist before the problem is logged; the problem record is always created first, and known errors are identified as a result of subsequent investigation.

Known error records are a product of problem management investigation and cannot be created at incident logging time, since no root cause analysis has taken place yet when the incident is first raised.

Known error records are independent of release cycles and should be created as soon as the diagnostic information makes it prudent, not deferred until the next service release.
