Known error

From Wikipedia, the free encyclopedia
Jump to: navigation, search

Known error is a term to refer to software bugs which have yet to be fixed but have a known root cause and either have little disruptive impact on the end user or a known work around.[1]

Tested systems are often described as "free from known error" 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]
