Simple definition
A known error records an analyzed, unresolved problem and the findings or available workarounds useful to support teams.
Purpose and use
A known error formalizes analysis of a problem that has not yet received its definitive resolution.
How does it work?
Documentation can describe symptoms, scope, findings and available workarounds to support related incidents.
Example and verification
Before applying a known workaround, verify versions, symptoms and prerequisites against the present case.
Points to watch
A record does not mean a permanent fix is available or that a workaround suits every occurrence.
In short
Keep the knowledge current and linked to the problem, incidents and progress toward resolution.
