Funktionsduglig

Funktionsduglig is a Swedish adjective meaning that something is capable of fulfilling its intended function and is usable in operation. The term combines funktion ('function') with duglig ('capable' or 'fit'), and is used primarily in technical, industrial, and administrative contexts. It indicates that a device, system, component, or process can perform the tasks it was designed to perform under defined conditions, and often in line with formal criteria or tests. It does not, by itself, guarantee high quality or long-term reliability, but signals compliance with minimum functional requirements.

In practice, funktionsduglig appears in procurement, maintenance, testing, and safety assessments. For example, a supplier may deliver equipment that is deemed funktionsduglig after passing specified functional tests, or a maintenance report may note that a part is no longer funktionsduglig and requires replacement. Functional requirements (funktionskrav or funktionella krav) define what counts as funktionsduglig, and verification procedures specify how to demonstrate it. The concept is distinct from merely operable; something can function but not meet the defined criteria for a given application.

Related terms include fungerande (operational), funktionskrav, underhåll, reparation, and kvalitetskontroll. Funktionsduglig is widely used in engineering, procurement, quality assurance, and regulatory contexts within Swedish-speaking environments.
