Feilfrie

Feilfrie is a Norwegian adjective meaning free of errors or defects. It is used to describe products, information, or processes regarded as correct and reliable. The term is a compound of feil (fault or error) and fri (free). In Norwegian, feilfrie modifies nouns, and, in practice, the form feilfrie is used for plural nouns.

In practice, feilfrie denotes an aspirational state in quality management, software, journalism, and manufacturing. Absolute faultlessness is rare; the concept signals high standards, rigorous testing, and ongoing improvement.

In industry, feilfrie outputs are pursued through quality assurance, verification, and standards such as ISO 9001 or Six Sigma. In software, teams aim for feilfri releases through testing and validation, while acknowledging residual defects.

Critics warn that the term can be marketing-driven or misleading when used to imply infallibility. It is most useful as a goal rather than a guaranteed condition.
