Known error

Short description: A software bug that has not been fixed

A known error is a software bug that has not been fixed, but has a known root cause and either has little disruptive impact on the end user or a known work around.[1]

Tested systems are often described as "free from known errors" in recognition that complex systems cannot be proven to be error free.[2]

In IT Operations known errors may be logged in a system's known error database (KEDB) which is then used to prioritize changes and to develop customer support reference information where a work around exists.[3] In the ITIL framework KEDB is a part of the Problem Management process.
